Jim and his crew are incredible, honest, and reliable. They know cars and are my go-to for all car related services, including but not limited to: oil, tires, breaks, alignment, and even car washing. I highly recommend them!

Wash is ok. Used the top level wash for my car ( 22$ ) and it Left multiple dirt spots.i was able to remove most of them with a cloth.

Very good car wash. It is hard on your surfaces, so if you worry about swirl marks its not for you. The attendants are good and the wash comes out well.

Had my brakes replaced, stickers for three cars, oil changes for two....all done in a professional and timely fashion. Great service! Also visit the car wash frequently, which is the best wash around.

Young ladies we had were excellent! 10$ car wash you cant go wrong, gets the job done perfectly!

They are very friendly and they have the best car wash in town

Literally a one stop auto shop... The best car wash in town imho!.. highly recommend it!

Great car wash and good service. It isn’t touchless, but I find the wash brushes to be clean, I haven’t gotten any scratches.

One Stop is the BEST! The level of care and detail that goes into the wash is amazing! Down to the very end when most car washes just do air dryers this wash has a machine that towel dries after the air dryers. Leaves no water marks! The team at one stop is super nice! Been multiple times! Will never hesitate to go back!

They do a great job 👏 I drive all the from lowell to that place

Best car wash in the state.

I will never go to another car wash again after coming here. Out of all the car washes Ive been to, my car has never looked as good as it does coming out of one stop! I drive 40 minutes just to come to this specific car wash, and they never disappoint. The service is top notch, the staff here are hard working, friendly, and make customers their top priority. This is the best stop for your cars and convenience!! I would recommend to everyone.

The best wash around, hands down!!!! Julia and Erin are adorable.

Best car wash in the area! Went through for the first time last week and very happy with the results! I will be back again soon!

The best car wash around for miles and hands down! The staff is very polite, respectful, friendly. Most of all they take their time on your vehicle like its their own! They spend time preping your vehicle before sending you through! I highly recommend One Stop Auto Wash to EVERYONE! Keep up the supreme service!

Good service. Im disabled and they got me a chair to sit in while I waited.Oil change and inspection. Reasonable price

So much better than Primrose. Real people, actually washing tough spots with brushes and giving extra effort to insure a job well done. Worth every penny. I will use this car wash every time.

Best car wash in Chelmsford! Definitely worth the $22 and I love the Dry ‘N’ Shine!

Jim and the guys are the best mechanics in Chelmsford. Maybe the best in Middlesex County.

They do a great job. Even though I no longer live in Massachusetts, Ill still stop here whenever Im in town.

Very friendly owner and female attendant. I plowed last week and my truck was absolutely coated with a thick layer of salt. My truck came out so spotless that I decided to get a memebership with them.

Great place, nice staff and fair deals. Great for oil changes and inspections.

They do a once over scrub before sending your car through the machines so it does a pretty good job. As with all automated, though, flat hatchbacks stay a bit dirty around the license plate and lift gate handle.

No vacuum by attendant. There are vacuums available for an extra fee.For $12 service car and tires are soaped up and brushed by the attendant while the driver sits in the car. Then the car goes through the automatic wash, rinse , and dry. Bring a towel because the car comes out with many wet areas and soap suds accumulated around and in the car doors, front grill and rear license plate. I’d rather pay a few dollars more and have the car vacuumed and dried off.

Good car wash. Fair price.

Great car wash. The attendant took extra care prepping the car before running through the machine. Car came out clean and waxed. Id bring my car back the next time I need a wash and wax.

Friendly, courteous, thorough! My car always comes out shining.

Cant comment on the service because I didnt get that far. They have a quickstop lube bay and it was 4:30 on Friday, I just sat in 495 traffic since there was an accident and figuring they closed at 5 or 6, i pulled up to the bay anyway. Two gentleman were just standing there talking even after i had my window rolled down while looking directly at them. They didnt stop talking even after I said, hi. They looked at me and continued to finish their conversation. I interrupted again and said, Sorry... Do i need to call ahead or is it possible to get an oil change? one guy walked away and the other fellow said, No, not today. Its almost 5. We close at 5. I didnt even bother to listen to whatever else he had to say and rolled my window up. Lazy... Put a sign up that states you stop doing oil changes at a specific time.

Terrible experience at One Stop Wash. If youre expecting your car to actually get clean, go somewhere else.The wash did a mediocre job removing some sort of black film on my hood. I dont blame them for that because it was on pretty good. The young female attendant hit it with the brush and spray wand but two grooves on the hood were still black where she couldnt reach. (Btw - SHE should be the manager because she at least made an effort.)Drove around a 2nd time and manager was there. He was easily tall enough to reach but chose to be rude instead. Initially, I wasnt angry and was even willing to do the brush myself. He told me it was not a detail wash, only an express wash. He said Id have to pay for another wash if I wanted to send it through again.There was NOBODY behind me! How much would it have cost to brush another 15 seconds and run it through again?!?Shame!

Great service and employees are very nice! They have a car wash too which is awesome. My car comes out perfect everytime!!

Car wash was just completely renovated. The new wash works great!

Better place to get a fast clean wash compare to other options around.

The owner and staff are extremely profesional and knowledgeable. The service is always on time and their place is very nice and clean.

Great service, better wash (involving a real human) than other touchless car washes. We use the $30/month unlimited wash package for my wifes car, and the $20/month unlimited package for my car.

The guy really washes the car with a power hose well before the car goes thru the wash cycle.

Great auto service and customer service,excellent too ! I had brake service , inspection and car wash.Bob Warren 11-15-2018

They do a great job preparing the car to go through and always gives the best cleaning.

Loved using the vacuum for my car!

Dropped my car of got it back the same day, the service was quick and they did a great job.

The new owner put some money into this place and its getting better everyday, update- 3/14/19 just went to the NEW carwash wow the kid put a whole new system in. The top car wash pkg. cost 22$ but its well worth it and best of all he fix the pothole at the end of carwash. What a nice guy, he got my vote for top carwash in that area. For the auto area I cant say much since I only go for the carwash but if that is nice I can only imagine.

Terrific service! My windshield wipers stopped working and they had me in and out in 15 minutes!

A very good car wash.

Great customer service and wash also

Its okay..but there is no better option available right now.

Great service!!!!

Easy to use
