Here's a polished Yelp review you can copy & paste: I stopped by Los Osos Car Wash in the middle of the day during the week, and the turnaround time was super quick--which I really appreciated. The service was honestly great. The team was incredibly accommodating, attentive, and made sure everything was taken care of without me having to ask twice. You can tell they take pride in what they do. Pricing is also very reasonable, especially compared to other car wash options in the area. I feel like the reviews here on Yelp don't fully do this place justice--definitely worth checking out if you're in the area! read more

Los Osos Carwash - Prices as of April 2026 - Car Wash Near Me - Rancho Cucamonga, California

Reading the reviews, you would think this car wash is horrible, but they did a great job. Staff was great, I can't emphasize that enough. But the CUSTOMERS, not so much. I can see why they have low ratings from the low life's that go there. Had a man with his son bring a Doberman without a leash and letting it run wild through the office and outside around the cars, then another guy on speakerphone talking about some STD he got from some dude in Mexico, all while children sit with in ear-shot. I asked one of the guys working the vacuum how his day was and he told me " I'm very lucky I get to work a job I love with wonderful people on this wonderful day." But then you have people on here leaving one star because their seat was moved when they vacuumed and their mirrors were moved when the employees dried them. read more

Not bad. Pretty good work. I was hesitant in coming because of some of the reviews. But I had a good experience and my car was clean

If i could do zero stars i would. I paid for a hand wash and hand wax which came out to 90 dollars. Idk if theyre rushing to get everyone out of there but it was literally less than 30 mins which is ridiculous. They left so many spots and didnt even clean my rims. Honestly. Worst car wash ever. Also the manager doesnt do anything but sweep trash instead of overlooking his employees work. Never again will i support this business. Dont waste your time or money with a handwash... read more

This car wash used to be my go to but not anymore. It's getting worse and worse by management not having enough staff to support the demand. Guys are working hard but there just isn't enough of them. Been here over an hour and it took 35 minutes to get to the vacuum area to drop off my car and now my car is stopped in the middle of the car wash waiting for the cars in front of it to get pulled out. Once you're in line you can't turn around. Bummed but I can't wait an hour and 28 minutes for my car to get washed anymore on a Saturday. read more

You want to pay $30 for a drive through car wash? But wait... it includes an interior vacuum. Sort of... you'll still have crumbs on your seat and trash on your floor mats. You will tip a guy to wipe down your car. Except he won't wipe down the interior because you didn't pay extra. You'll have still have dirt on your car. Why? Because you only paid $30 and it's all extra and they're too busy for that. Avoid this place! You'll get a much better wash elsewhere for a fraction of the price. read more

If I could give no stars, I would. $50 later and this is what my backseat still looked like. Please take your money elsewhere. read more

Used to be good. Imagine with me for a second that you pay way over $100 for a wax and wash when they finally get done there's dead bugs all on the front bumper. So you show the guy and he says that's from rocks on the freeway and you take your finger and you start wiping bugs away in front of him and he then takes a dry towel and just rubs them in. It also feels like they're looking around sizing you up to see whose car is who. read more

The first time I ever came here they did great my truck looked brand new on the inside and he was great I came a few weeks ago and they told me they couldn't wash my truck cause they needed to hand wash it which didn't make sense cause they hand washed my truck last time but anyways I left and came back yesterday not only did they not do a good job they completely missed the whole bed of my truck and didn't clean the inside of it my interior is still covered in dust I paid for the gold wash and extra for a hand wash just for them to completely miss whole parts of my truck. I don't understand how you miss spots that bad read more

I received absolutely horrible service today at Los Osos car wash. I wish I would've read the reviews. (I usually go to Haven car wash. And have no problems getting my car cleaned there!) However today when I went to Los Osos car wash, I came home with a dirty car. I returned to the car wash to ask the manager about the spots I can literately not rub off. He said it is sap and I can return in a month and pay $180 to have it removed. I asked for a refund because my car is not clean. He refused and throughout our conversation he became aggressive and rude. It made me extremely uncomfortable and a. He said he would rather loose my business than refund me money. read more

Just paid $51 for someone to rinse my car through a machine and not even vacuum my entire car. Crumbs are still all over the seats and floor, they left noticeable streaks of product on the windows. Nothing was done to my car at all. Literally they ran it through the machine and called it a day. read more

I'm glad I found this place. They left my floor mats like new and I have pets that shed a lot. The prices are great.

I went in for a car wash today and I had to say I was dissatisfied with my vehicle. I've been coming to osos car wash for more than five years with my smaller mini Cooper, but with my new SUV, they seem to lack in that department in cleaning such a bigger vehicle... I've never had any issues before up until today and I'm really surprised on which why they left my car so dusty only after being dirty for two weeks. I purposely come to osos car wash because of the reasonable price and good of service they clean inside the car...but I'm very dissatisfied of which how it came to be. I just advised future customers to look thoroughly before you drive off like I did. I'll be giving it two stars due to the fact my outside of my car looks fine but the inside nothing looks like it's been changed... read more

Don't come here. I mentioned that I was before 2 cars, asked if I needed to move my car when I first got there. The minion taking the orders got a power trip & sent 5 cars in the tunnel before me. When I talked to the manager about it, he tried to gaslight me, condescendingly saying "we can only put one car in the tunnel at a time" obviously, but my car shouldn't have been 5 cars behind. The workers giving the receipt when you first get there are spiteful little roaches, save yourself the time & money. read more

This used to be my go to but the last two times it's been disappointing. One time took 25 min to get it out of the wash. Had to leave without even wiping it down. This last time, the passenger seat was wet. I think windex? They tried to cover it up with a personal belonging. read more

I came on 9/27/2025 to get my car washed I paid $31.99 for my service! It wasn't busy at all, I had maybe two people in front of me. This is slow for a Saturday at this place. My car was dirty and the inside was very dusty and had dog fur from my shoes on the floor. They left trash in my car on the doors like gum paper and water bottles car was still dusty and full of dog far. It was like they were scared to vacuum my car. I still have bug juice on the windows still have dirt on the car. They just did a horrible job. I asked for new car smell. I smell nothing as if they never put an air freshener in there which I see they did, but it was almost as if it was used because there's no new car smell. I just was not pleased at all with the service I received and for me to have spent $31 to leave when my car is still messy and dirty. It's so disrespectful. Yes it's my fault for letting it get this dirty. But I paid for a service I didn't get. read more

Not surprised by the rating. This place used to be really good a few years back. Now they rush the cars so quick that they leave certain parts of the car dirty or un clean. My car still had the inside of the door panels dusty as well as the dash. They didn't clean the center console either in all I give them a 4 out of 10. I will have to fine a new place. Not coming back here! read more

This was the worst Car wash. I have to say I may have ever paid $35 for. I have a Tahoe... I made sure the back was cleaned out so it could be vacuumed, it was not. I made sure all of the trash out of my car so it could be completely wiped down on the inside, it was not... I just spent 30 minutes doing what I just paid somebody else to do... I went once before and paid to have my car waxed... Went and got my nails done while it was being waxed... Came home and my husband said there is no way that this car was waxed the next day when water did not even be off my car at all... I have been pretty unhappy with my last few services... Before you leave do a inspection of your vehicle... Do not leave until you are happy read more

I used to come to Los Osos Carwash regularly, but after today I'm done. The wash itself is fine, but the way they handle vehicles is not. When I got back into my truck, I noticed my right mirror had been folded forward and then readjusted by the staff. Annoying, but manageable. What isn't manageable is that they keep moving my seat even after I've repeatedly told them not to. I even use a small block of wood to keep the seat from being pushed all the way back and reclined. Today they removed it and pushed the seat back reclined it again. Then I discovered the real problem: they had put my truck into 4HI. This isn't something you can do by accident--you have to press a lock button and intentionally switch it. When I tried to reverse, the truck barely moved, and if I hadn't caught the 4WD indicator, I could've caused serious drivetrain damage. This level of carelessness is unacceptable. I can't recommend this place anymore. I'm looking for another carwash. You should too. read more

Great local spot. Great people. Great vibes. A touch pricey but what isn't these days. They get the job done.

Great customer service first time there car is still a little dirty inside. Thought they were doing a lot better. I think Fontana does better than them. You know what the funny thing is the guy gave me a dirty look because I didn't give him a tip. I don't think he really deserve a tip if you don't clean it properly. read more

Rude rushed and not good for the price you're paying. Asked the guy if he would vacuum my trunk twice and even opened up the trunk for him just for him to say I never told him so obviously I corrected him. The car was sitting there for God knows how long and nobody told me it was ready until I got up to ask one of the others working on a different car. Save your money go somewhere else! read more

First thing is, I've been bringing my car and wife's car for hand washes for awhile. I brought my car in for a hand wash and as I was driving home water was flinging then when I got home I started giving it a better look. The door jams and windows were still covered in dirt. Then I lifted my son's booster that is not strapped in and it wasn't vacuumed under. The front seat wasn't vacuumed. The center console and cup holders were dirty not whiled down. So I went back. The " manager Daniel " gave me attitude that I wasn't happy about my car not being washed. The outside of the car especially the front grille was still dirty. I told him to wash it again per what I was told over the phone. And he said they don't do that. And I said ok and walked back inside to speak with the lady. She said they will. As she stood by a sign inside their lobby saying " if you are not satisfied with your wash we will fix it until you are satisfied" So I went back out there and handed him my keys and told him that she said to rewash it. When they were finished. My car was the same. All the door jams were wet and dirty. And said this is one of the reasons I came back. They I said just give me the rag I'll do it myself. And he handed me the rag and watched me clean my own car. The manager doesn't give a shit this car wash has gone down the drain. read more

Meh. It's a carwash. Depending on who you get to dry your car, it's hot or miss. Overall they do a good job, but there was still dust on the dash and gauges. As an added bonus (not) they always re-adjust my seat to THEIR needs. If there is anyone from the carwash reading this, please dont re adjust seats. Not everyone has memory seats. 3-stars because they lack consistency. read more
