Went to Carcode to get my car washed last week and was not disappointed. I am one of those guys that really neglects their car until it is way too dirty that it becomes embarrassing to drive around regularly. So as a preface - yeah, my car was really dirty. I opted in for the $22 wash with the matte finish. I was told it would take around 45 minutes to an hour which was fine. I just sat and waited as they took their time to clean my baby. I didn't mind because I noticed they were making sure to get all the little nooks and spots that other car washes just ignore to get you in and out in 20 minutes. This was definitely a plus on their part. At the end of the was, which took about 50 minutes in total, my car was spotless and reflectively shiny. I think it was the best $22 wash I've ever spent. I have definitely paid $40 at other places to get a wash that was not as good. I would recommend this spot 11/10 times to anyone in the area. Thank you Carcode, you have my business! read more

I was looking for a new car wash place with decent reviews and found this one. I called first before going and the guy who answered was very friendly. I went there and the lady who helped me was very nice too. Price was very affordable and they did a good job cleaning my Tesla. I removed 1 star as they missed a few spots but overall I was satisfied with their service. Recommended! read more

Hours are wrong they close at 12 noon on Sunday. Even still got there at 11 Am and said she can't wash the car. Guess they don't need the business read more

Very unprofessional. I called in and asked for the price of a car wash and vacuum. Andy said it was $35 and last call was at 4 so I arrived here at 3:15. As soon as I got here, Maria said they wouldn't take anymore cars due to "weather reasons" although weather was perfectly fine. I called Andy again to see what was going on and he assured me they were still taking customers. I went back to talk to Maria and she gave an attitude and raised the price to $40. read more

I had been in search for a quality car wash in my area for months and had taken my car to a few places only to be completely disappointed. Found Car Code on Yelp and it didn't disappoint. I came on a late Sunday morning and there was only one car ahead of mine. The people are so friendly and have such an eye for detail. You definitely get what you pay for and I'm so excited to have finally found a quality car wash! read more

Car Code Auto Spa - Waiting area - Car Wash Near Me - Walnut, California

I have been looking for a place to take my car to be detailed & waxed. I found Car Code Auto Spa. I called & they suggested I stop by to talk to Maria about price & when I could drop it off. Maria was busy & when I said I didn't want it done today she was the nicest person. She inspected the car and suggested Friday morning drop off. She says she needs to bring in more people to work. I dropped it off and she called after 1pm to pick it up. It was beautiful & so clean, it looked better than when I bought it. Maria & her crew did such a great job, 2 weeks later we stopped in to make an appointment for my husband's car. read more

This car wash is amazing. Plus they have a cafe inside. You should try their auto repair shop too! read more

Car Code Auto Spa - Menu - Car Wash Near Me - Walnut, California

This place is fantastic! This is hands down the best car wash I have ever gotten. Now, it's a small place and they are hand washing, so be prepared to wait a bit. But there's plenty of places to sit. Everyone I came in contact with were very kind. From here on out I will not go anywhere else. I 100% recommend!!!!!!!!! read more

I'm leaving a review here too simply because Valley has a contagious laugh and gave me the most pleasant phone call to make sure my car was being taken care of. I actually have my car on the other side for a carwash but sometimes a simple pleasant phone call can make a client out of me and my car definitely needs work :D will update my review when I do read more

RIDICULOUS PRICES!!!! Used to come here all the time, when it was reasonably priced and the previous owner managed it. This place is absolutely crazy trying to charge $60-$70 for a small SUV!!!!! Save your time and money and go somewhere else read more

I had the car wash and hand wax. Everyone was really nice. Everyone was very responsive. The wax they use repelled everything. Same price as other car washes. But at car code auto spa, way better service and quality. read more

Dropped by on Saturday morning around 9:30am and was out by 10:15am. My truck was filthy from being parked outside during quarantine and the Jacaranda trees were starting to make things worse. I usually go to Diamond Bar Hand Wash, but after many mediocre washes I wanted to try a new spot. I found Car Code and wanted to give them a try. There were 3 other cars ahead of me, but they took care of me rather quickly. I was really impressed with the attention to detail and it looks like I may have found my new car wash. I spent $24 (plus tip) to wash my truck and I was really pleased. The staff was really friendly as well. read more

This hidden car wash is amazing, sometimes car washes rush the cleaning of your car but not here! They did an outstanding job. They also have a little cafe inside and I was offered a free tea while I wait for my car, it was delicious. Customer service was outstanding and I will be returning to this car wash for services and have told all my close friends and family. Thank you so much car code! They also took me the same day, I called before. read more

Always very nice and professional. Really good attention to detail. By far the best car wash I've ever been too, and the prices are really great! Definitely check this out! read more

My parents recommended Car Code to me and my car was in desperate need of a detail. I did the ultimate wash which included both exterior and interior services. I dropped the car off around 12:30pm and was told it would take 2 hours to finish. I did ask to pick up closer to closing and the employee said they closed at 4 (even though their Yelp and another employee later said they closed at 5). I called around 3 to see if my car was ready but they said it wouldn't be done until 4:30. I was running late so I had my dad pick up my keys and picked up my car a little later, I was grateful they were able to accommodate this. Unfortunately, it started raining right around the time I picked up the car but it was definitely noticeably cleaner, especially the interior. The wash totaled to about $35, not a bad deal for the service! Wouldn't mind coming back but definitely need to work on the timing a little more. read more

Went there 4 days ago. First impression was good. Not too busy and the place was clean. The waiting area was also clean and you can see the worker's cleaning your car. The reason why I'm giving this place a 4 start because they miss a spot and it was located near the a pillar. I mean you can't miss that. But over all it was a good experience. Going back there soon. read more

They clean my car fairly well and I was happy with the result. I don't notice any swirl marks or new one and I hope it continues that way. I will keep coming here to help remove deep dirt on my car that a touch less car wash can not resolve. read more

I've been coming here for years and I have to say it's the best carwash in the area, service is top notch and I highly recommend it. Avoid weekends because the wait might be long, they do a great job! read more

They are very friendly and do their best to make everybody car great. They're a little short-handed but even then no one slacks off, constantly lots of cars coming through. I definitely enjoy using their service, long wait but glad there is at least wifi fight off the boredom. Or they can call you when your car is ready. read more

Car wash options in diamond bar/walnut area are pretty subpar and hand car washes in particular are pricey for the quality. So I wasn't expecting much when I decided to give Carcode a try. When I arrived they were still doing renovation but the car wash was up and running. The place isn't very big and was minimally staffed so it took awhile for the person vacuuming the cars to come up to write my ticket and take my payment. I opted for the basic wash. It was $19 and included armor for my tires. It took a long time but this was the first time I ever drove away from a car wash and no water came running out of my side mirrors. So I will definitely be back. read more

As a Carwash, this place was just OK. It's unfortunate that the quality does not match the price they charge. And I was hoping they would deliver since I'm wary of other car washes to handle a Tesla. Saw that they've worked with Tesla's before, so I had a bit more trust for them. I came by for a wash and wax, and at first I thought, "Cool, I'm the only one here right now so they should be able to focus a bit more". Nope. I've had better Carwash results where the price isn't so up there. They had 3-4 guys working on my car?? They didn't vacuum my seats properly (I have white seats) and there were still oil splatter marks on the hood... if you're lazy or don't have time to wash your own car, this would probably suffice, but I'd go back to washing my own car or go to an exterior-only wash and get the same result for 4x less of the price here :\ read more

$33 car wash, after over 1 hr wait. There is water stain on the windows, interior was sticky, and stains found at back of the car. Also leaves were left wet and sticky inside the car. No words read more

So happy to find this place. Inside of car was so dirty from going to a farm with kids. Car code did outstanding job of vacuuming 3 row suv. Inside was spotless including spill on seat, cup holders, and dash. Outside was great too. Tires and rims sparkled. read more

They gave my car the best wash it's gotten in a while. The amount of time and effort put was about the same as if I did it myself at home. Squeaky clean. Their customer service is also noteworthy. Thumbs up! read more

I am so blown away by the results of the car wash and detailing from Car Code. This is probably one of my favorite car washes to go to and I'll be coming here from now on. The workers, especially the manager, are very friendly and very easy to talk to. They have different variety of packages to choose from, depending how you want them to clean your car. Definitely worth the price! read more

doors. Disnt vacuum very well. They locked the keys IN the car!!! Luckily and thankfully we were carrying a spare set. Theres still hard water marks on the windshield, and windows. you can tell they didn't use a microfiber cloth. There are still areas of the car, and mirrors that can be cleaner. I wiped my fingers across areas, and they came clean. Maybe its because they were rushing because it was almost closing time. (3:45 on a Sunday and they close at 5:00) Maybe we will give them another shot... Maybe not. Who knows. We will see read more

Great service. They did a great job on my car. Took a little longer than usual but it was worth the wait. I also forgot to use the coupon but she allowed me to use it and get $5 off for a wax job. Overall great experience! read more

All I can say is that I'm impressed. A hidden gem. I'll be back. Excellent for any car but especially if you have a matte finished car. This is your go to place for a satin or matte finish. Ask for Leo or Maria. I discovered this place driving by and saw a car with a matte grey finish just recently washed. By this alone I was impressed... 99% of car washes and detail shops will not even entertain washing a matte paint job (because it's very costly to repair if damaged) but Leo and Maria here at Carcode Auto Spa assured me that this was something they felt confident with. I haven't been able to find somewhere that can wash my matte car and I'm so happy I finally found one. I gave this place a shot and it was well worth it. Leo and Maria took their time and didn't rush like most other car washes. The price was excellent as well. I will for sure be back when I'm feeling too lazy to do it myself. read more

I thought I just came in on a bad day but I have been to this place a few times now. First, for a complete detail on a car that I was giving to a friend in need and then a few times for a wash for an SUV I bought. For the prices I have paid, this place is not doing the quality of work that I paid for. On the detail, When I picked the car up I noticed that there was a big black smudge mark on the sun visor that should have been cleaned. I chalked it up to just being human. We all miss things. I have had my new SUV washed a couple of times there and each time I had to ask them to remove dirt/ water that should have been pretty obvious to them. I don't know what the problem is but my experience has not been good for the price they charge. I could do just as well at the drive thru. Done. read more

They did a Horrible job, i basically paid 36$ per car for an express gas station car wash. I brought 2 cars here and paid for the ultimate wash, after 2 hours of waiting when they handed me the cars, the interior was still very dusty and still lots of dirty splashes on the exterior. I had to wait another 1 hour for them to rewash everything read more

Great service. Always come here by appointment for an oil change and service they always address my concerns with my car. I am very picky with my European car this is the only place I would take it in for service. Way better than this dealership. Thanks guys read more

Very very expensive place and looks like no other cars but still you have to wait 40 mins

I gave two star just because the price is okay. Not good. I mean I went there twice and every time they leave a lot of dirts and said all set and I'm good to go. And one of the guy is very rude to ask for tip while I'm finding my wallet to get the cash! The price is okay but the quality is not that good.Definitely won't go back. read more

Inside is dirty as it was. not worth 51 dollars for sure. should trust the othet reviews read more

Went a few days ago and first impression was ok. Very slow service though. It took over an hour to have my car washed and dried and there were things that looked like dust on my window screen. Overall, I paid money to not even have a clean car. After a day, I can see all the dust and wafter marks that weren't cleaned. SAVE YOUR MONEY, DONT GO read more

Just wanted to give this place a shout for helping me out on my S2000. Exterior was seriously in rough shape but after they finished it, Car looks amazing and alive with the detailing. Swirls/scratches begone!!! On top of that they even offer me a free wash and wax when the weather is good again. I will definitely recommend anybody that wants their car detailed. Awesome Job guys!!!! read more

Car Code Auto Spa - Forgot to take a before picture but this looks amazing. Its like a mirror now. - Car Wash Near Me - Walnut, California

They did a fairly good job. Just got done with a 2500 miles drive, and my car was understandably filthy as can be. I opted for the cheapest option, and it seemed like they cost most of everything clean. Most importantly, they cleaned off the bug cemetery off of my bumper. There were a few missed spots that I had to quickly go over, but nothing major, and it was expected for the price paid. Overall, I'd be willing to go there again. read more

Great place to get your car wash, I usually do it myself because I don't like paying money for a mediocre car wash anywhere else. I was very impressed with the effort and attention they put on my truck. Try it out you won't regret it. read more

Love it,I took all my cars here,it is so clean!They clean up your car look good like new!

The best place to give a good service to your car great services the people who cares about to provide like detail on your automotive.
