Diamond Car Wash is one of the best options in the area, especially for larger vehicles. We own a Suburban, and they consistently take the extra step to prewash the tailgate, bumpers, grill, and sides, which many Washington drive‑through car washes do not do. The staff is always friendly and they guide your vehicle in carefully to help prevent any wheel damage. I recommend the Super Premium wash, as it delivers the best results and includes rim cleaning and tire shine. The only drawback is that the wheels are never fully cleaned. There is always some brake dust left behind, and if you enjoy a spotless vehicle like I do, you will need to finish that part yourself. I would wash the entire vehicle on my own, but due to a bad back I rely on car washes, and overall Diamond remains my preferred wash. read more

Quick service, decent price, and vacuums that take card. All I could ask for a car wash!

January 19, 2026, 2:52 PM; The guy at the register was very disrepectful to begin with. My Yukon went through wash, and came out with substandard results. He contested it but sent it through again. afterward, on the lower front fender behind the front wheels was still not washed on both sides, and he told me: "that's all we can do". Actually the entire lower sides below molding were completely covered as before the wash. Then Mr disrepectful got even more disrespectful. This was the worst car wash experience ever, and I even tipped $5 to the dryers. The absolute worst!! read more

odd that the score here is three stars. very very seldom do I need to touch up drying certain places. I would give these guys 4 1/2 stars if i could keep up the great work you all do read more

For what you pay, this is one of the best options around this area. I actually drive past two car washes just to come here. Employees have been friendly every time and they always dry my car for me at the end. Every other car wash around you dry it yourself after the blower doesn't dry your car, but not here. I don't know why there are bad reviews? It's competitively priced yet offers more service for the same or less than other washes nearby (I live in Bothell and drive to mill creek for this wash). Sorry, but other options are Aloha and Papa Bears car wash and neither one does a great job or dries your car which is why I go here! I have a new car and have been many times and never had scratches or any problems whatsoever! read more

Nope. Just drive the extra five miles to Brown Bear. Narrow space, unkind, lackluster.

ordered a tire shine and the fucker with mullet didn't shine shit had to hop the car and slam on to the pavement for him to actually do a proper cleaning. would to do again read more

Hey, this is a great spot for a clean car. Not only is the cost reasonable, but they have an employee pre-washing your car before it enters the car wash, and another employee hand-drying your car when you exit! In my opinion, it's the hand-drying that sets this place apart from your standard automatic car wash. The only suggestion for improvement is a tip jar on exit. I don't usually tip before a service is performed, so having some place to put a tip once finished would be nice. It was a busy Saturday so I didn't want to hold up the line trying to figure out how to tip ... I'll look harder next time. read more

Excellent carwash. They pay attention to detail. Always clean and friendly staff. I've asked them to vacuum my car have done so when not overly busy. Just friendly and considerate read more

Not sure why so many negative comments have been posted. I've been coming here for years and never had a bad experience. Obviously on nice sunny days they are more busier than non sunny days and might miss a spot, but otherwise they do an excellent job. I take both my BMWs and they always get all the details. $18 bucks gets you the super premium wash which includes the best wash available, rims and tires washed and cleaned and whole car wiped down. All the folks that work at this spot are always friendly and courteous. In my opinion, this is the best car wash in the Snohomish county area. I've been to many, and this spot beats them all. Highly recommend if you ever need your vehicle cleaned. read more

This car wash is the ideal balance of speed and quality. If you don't love the uneven, lackluster cleaning of a drive through car wash but love the speed, this is the place to go. It combines the detailed attention of a (quick) handwash by an attendant with the speed of a drive through. The hand toweling at the end is the cherry on top. read more

This car wash has gone down hill over the last few years. The employees are lazy. Twice now I've paid for the top one and haven't gotten full service. They didn't even touch my wheels or tires. They used to be great but not anymore. I won't be going back read more

Very good. The two boys that work there brushed/bubbled my car before the wash. Then dried it with towels after the drive thru wash. Thank you. read more

Had a very bad experience with my truck. Bought the Delux Car Wash. Sure we all know fast machine car washes don't do justice in cleaning your car perfectly. It all comes down to service. After going through the car wash the guy in the left did a great job wiping down his side of my vehicle. But the other guyon the right side just barely touch the vehicle. Skip the hood and front side window, went directly to wipe half of the passenger side and raised his thumbs saying ok. I pointed that he missed the front hood. Then he continued to wipe it down. Then he raised and gave me the thumbs up again. I pointed the front windows needs to be wiped down. He then moaned and was upset about not wiping the front window, side window, and whole side of the car including the side mirror. I then stepped outside the truck and see if they missed anything. And luckily the guy in the left did a great job and finished wiping down the side the lazy guy was supposed to wipe down. Or else I would of come around again and get a re-wash. We are paying good money to have our cars cleaned and are busy doing our daily schedule. Just do your job and do it well. As a business owner we focus on customer service. But unfortunately, they have poor customer service and attitude. This unfortunately will be my last time and will not be coming back and have lost a good customer. Go somewhere else that cares about your vehicle and will not give you attitude. Your hard earned money is better spent somewhere else. read more

This review is more for the employee with the dark curly hair working the car wash all by himself at 3pm on the first sunny Wednesday in months . He rang up the service, scrubbed the car and sent me through the wash. Afterwards I was surprised to see him come running over to my car to dry it. He ran back to the beginning of the cycle to get the next car through. There was quite a line of cars waiting to go through but he was calm and multitasking and very polite and personable. I'm sure there was someone else scheduled to work soon but this kid had it handled. He's going to go far in life whatever he chooses to do. Great job guy! Wish I saw your name and that you get some kudos from this review! read more

Got the premium wash $18.00 with tax. Little more than brown bear but this place actually pre washes by hand before going into the car wash. On the way out it got hand dried and they also hand washed the tires. At brown bear they don't even touch my car and they act like robots when you drive in. The guys drying were nice and appreciated the tip. Car looks good and wheels and tires are extra clean, didn't have to clean them myself afterwards like normal at brown bear. Would return for sure. read more

Diamond Car Wash - Pricing - Car Wash Near Me - Mill Creek, Washington

Tired of paying for the premium wash, plus gratuity only to get home and find the car looks the same. The tire rims and hub caps are just as muddy and my car still has dirt all over it. I always have to go over it with some simple green and a wet microfiber cloth for about 45 minutes after. I don't know why I bother. read more

It's similar to a Brown Bear type wash where you stay in your vehicle while it goes through the automatic wash. The basic wash was $7.99 and after you exit the wash an attendant uses a towel to quickly dry off your vehicle . There were also vacuums for use, but I didn't notice if they were free. The basic wash was acceptable and it's very convenient if you live in the Mill Creek area. read more

If you plan to go here I suggest you plan on spending about $17.99. Do not make the mistake of getting the basic wash for $7.99. It is a joke, and does not do anything for your car. My car left there looking worse than before. P.S. They are not friendly at all. read more

I paid for a super premium wash and also asked for vacuum inside the SUV and I was told that they cleaned around 350 cars that day, that if I wanted my SUV vacuumed I had to wait 2hrs (I was the only one there and also another SUV behind me) because they did not have any rest on those 350 cars. I did not argue or something, I just got the super premium wash and I left the place, which I'm not planning to come back. You have a very lazy people there, really disappointed of the service. read more

It's better tui drive a dirty car than waste your money here. $20 and the car is still filthy

Just got back from a weekend camping, hence the trip to the carwash. My back tailgate was dirty and I also wanted to clean out the inside. This is close to my house and have been here before but after this trip, I won't be back. When I got home, I was shocked to see how dirty my tailgate still was! This means 3 people found this acceptable! It was not power sprayed or scrubbed pre wash and the dude drying it off just spread the mud around and didn't say anything!! And you're going to charge $10 for that!? BAD BUSINESS! read more

Diamond Car Wash - Back of my car is still filthy after a $10 car wash! - Car Wash Near Me - Mill Creek, Washington

My wife and I have used this car wash a couple times before. Not sure why I keep going back here because the machines really don't get the sides of our vehicles or the tires very well so we decided to upgrade this time and buy the $16 deluxe package. I think the towels that the guys were using today were dirty or just not dry enough to pick up the water cause there were streak marks all the sides of our vehicle now. Tires are still dirty as you can see in the pictures. I will not go back here ever again and it's a shame because I live 5 minutes away. read more

I have tried all wash packages they have and yet never took a clean car afterwards. Very poor job in drying car after wash. I end up touching up the car after i wash it. Not worth your money read more

I have to give this place a 1 star service sucked I payed for a super premium wash went to inspect my SUV and there was still dirt on the back and sides of my car. It comes with a hand wash wheel and tire shine I had to remind the employees what I payed for and they did a very sloppy job of doing it. Worst $20.00 I have ever spent. Lost my business I will not be returning. read more

I have to agree with Arun C. I had my car washed when it was dirty (mind you not excessively nor out of the ordinary). Their prices are fairly steep, considering it's just a regular car wash. Sure they spray it down before you enter, and somewhat wipe it down after you exit, however it still left spots and dirt in the wheels, and exterior visible gaps (eg. the door to the body, the trunk to the body, etc.). Like I said, it's ok, however this is NOT a case where you "get what you pay for" (you get a bit less). On a side note, the CIrcle-K that its there usually has great prices on gas, however that's for a different review... read more

Very disappointing. Don't spend the money on the two more expensive "deals". I opted for the $17.99 wash. I don't know what the "hand prep" car means, they moved so quickly, I saw nothing special with their treatment. I asked if they clean the inside of the car and they said not when it's busy - there was one car behind me. Anyway, lesson learned. read more

To be honest, I only really come back because there's a cutie who works every single time I decide to get my car washed sooooo......... With that being said, this place is an alright car wash place and I only come here when I'm in the area. Prices are a little on the higher side for the super premium and premium washes, but ummm, I really couldn't tell the difference between those and the most basic wash. If you're not really in dire need of a car wash, wash your own car or go find yourself a Brown Bear car wash for a cleaner, more thorough wash. read more

Went here for the 1st time today. Very subpar work for them to have attendants to wipe your vehicle down. I still have a fair amount of dirt on the rear of my vehicle read more

Went through today and paid for the $20 wash to get the tires hand washed, etc. Got home and saw that a spot on the back was completely missed; it should have been in plain sight when they dried the car and the tires. Disappointing and will never be back here. Took another car through a few months ago that had soap left on it and even heard them talking about it while they dried it - I figured they would fix it since they noticed but when got home it was still there. Two strikes.. Won't be back here. Absolutely ridiculous. read more

I live in the area, and this place is always packed on sunny days. My car needed a wash, so I decided to give them a try (no Brown Bear nearby). Priced seemed high for the "Super Premium" wash, but the list of services included was extensive. So I went for the $17.99 option. The "hand prep" consisted of the usual circling around the vehicle with the brush, then on through the tunnel. Right away I could tell it was sub par. Far inadequate of a rinse left suds all around the windows and windshield as I was already going through the dry cycle. The dry was also terrible, though the attendant did do a hand towel dry. He also sprayed the tires with tire spray. Upon further inspection, the rear around the license plate, as well as all along the passenger side had obvious dirty areas which were missed. It's a white car, and painfully obvious, and should have been seen by the attendant as he was doing the tire spray. So, lesson learned. Don't waste your money here. read more

This is a basic car wash. It is a waste of money to spend on anything other than the most basic wash. Regardless of the wash you purchase it takes about the same amount of time and there is little detailing or commitment to excellence at this place. I purchased the number one $17.99 which included handwashing the tires and wheels and applying a special shine. The boys took all of one minute to do all four tires and wheels. Definitely not worth the money and will never pay that again. read more

I have always gotten a great car wash from here. It's an easy stop on the way home from work.

I gave them two chances. Not coming back. They left a bunch of dirty spots and even missed a spot of bird sh#t behind. How do you miss a bright white spot on a dark colored car?!? This after paying for the super deluxe wash. Don't waste your money! read more

The price was definitely worth the service, they even hand dried my car after the wash. Try them out if you're in the Mill Creek area.

The young men who helped me were quick to guide me into the wash, and the workers hand dried my Car quickly and efficiently after. Best car wash in Mill Creek! Highly recommend. read more

I have been a satisfied customer for a few years mostly due to the hand pre wash before going into car wash. Today I went and found they have new equipment in the automated car wash section. I guess the owner has so much confidence in his investment, that he did away with the prewash. Bad, bad idea buddy. The car looked like crap afterward. Even after the poor kids tried to wipe all the dirty spots off while drying the car. I got out like I always do to inspect the car. The back end looked like it had been 1/3 cleaned and had dirty spots all over the car. This is the dirt from the recent snow and road sanding. I will not be going back, unless I see the prewash come back. Additionally, I paid the $18 premium price. Which needs to stop continually going up in price too! read more

Great place for a simple wash, used them for years. Fast and does a great job. $7 per wash

When the boss isn't there, they hesitate to do any full service washes. But when there's a supervisor, they just do what they're told. If you aren't going to ever do that service, why offer it in the first place? read more

Do not go here if it's busy you will get a half ass car wash. I just got home after going to the Shur-Kleen car wash in Mill Creek. I paid for the #1 premium wash and they missed large spots all over my car. There was a line to get in so the employees were not taking the time they normally do to prep the cars before they go through the wash and the hand wash tire package I paid for was half ass at best. Needless to say, I just rewashed my car and wasted $17.99. read more
