I love this car wash! The staff is very friendly and very hard working. Our vehicles always sparkle after a "bath" at Synergy. I like that it's a hand wash and not machines. They do a great job vacuuming and cleaning the windows too. Also a plus, the prices are really good. Don't forget to tip the staff ;) they deserve it!

I've never heard of a full service car wash refusing to detail a car because it was too dirty. Admittedly the interior of my car was a mess, I'd just driven across country with two toddlers but it wasn't THAT much of a mess. The impression I got from the man working was essentially "I don't wanna"

They did a great job on my truck and it was a great experience. I will definitely go back the next time I need it washed and detailed!

If you’re looking for a decent job I wouldn’t recommend going here to pay $50 dollars for a wash and detail. They weren’t shy about doing a terrible job right in front of you while you watch. I read the reviews before going thinking people were being too critical. That’s not the case, they are actually that minimal. I ended up using their vacs and cleaning materials and working on my car myself before leaving. && the whole time the “manager” watched me like he didn’t care the customer was unhappy.

They work very hard on cars there. The only place i have went too like it is in Hickory, NC and they were a little cheaper but these people will let you watch them work etc. Very nice just a little pricey. 😇 Did amazing work tho

Great place to bring your car for a wash. They hand wash the outside of your car in a conveyor system-like set up, then air and hand dry. I haven't done an interior cleaning yet, but not sure they have the man power capacity on a busy day to do a really good job. I expect it will be a fair job done, though, based on the previous posts.

NOT a "touchless car wash". They have ‣ guys with rags wiping down cars. Also, does not have under body spray:

I guess I should have paid better attention before I left. I opened the back up on the van and there were some rust stains on the matt and the 2 guys doing the detailing said they scrubbed the hell out. I opened the back up when I got home and realized they didn’t even pull the mats out to vacuum the inside. Then I realized there was some grease on the passenger side fender that was not touched. They were in a hurry to get done with the vehicle. I would not recommend this carwash until they hired better people who cared.

I've brought my car here probably a dozen times and I've always been happy with the results. I usually get the full service including tire shine and hand wax. For $37 im pleased with the results.

I am not in the area often, but when I do pass through I always use this car wash. They are quick and do a great job. Plus, it never scratches my vehicle up and they don't double charge (I have experienced that with another car wash in Knoxville). Highly recommend!

I've seen mixed reviews for this place. Just moved here and thought I would give them a shot since they're a "hands only" car wash. I could not be more impressed with them. They went above and beyond for me. I would definitely recommend and I will be coming back with my wife's car soon. Thanks guys

The first time I went here, I was very pleased. The second time… not so much. One would think I’d you’re paying for an interior clean, it would at least be wiped down. This is just awful. It’s like they didn’t touch the backseat at all. I’m giving 2 stars because the outside looks decent. I won’t be going here again.

I had never been to this place before, but after buying a new vehicle I was skeptical of going to an automatic car wash. So I came in and everyone was super friendly and helpful, and also great at what they do! For $37 I got a full hand wash, and wax, and interior detail, within like 30 minutes! That was on a full size truck, and it looks as good as the day I rolled it off the lot! So many great things about this place and I will definitely be back, and recommending them to everyone!

Place used to be awesome i would take my vehicle there and get a full detail in and out. They now just wipe inside down with a towel, barely clean the floor mats, no longer do the liquid wax and my tires are dull. Once they changed name and services offered I will not go back

Down from 2 stars to 1 star. We came here a year ago and were disgusted with the cleaning then. However, we decided to try again a year later. Maybe they had improved in a year and changed their employees. We can only hope! NOPE! Still the same disgusting job. I understand that for $27 you won't get perfection but at least a decent cleaning. There was still encrusted dirt in the side holders. The floor did look as if it was vacuumed but it was a sloppy and fast job. One year we had paid $25 for a car cleaning and it was a job well done. Too bad we could not remember the guy's name or we would have gone there instead even if the price went up. ----------- We came here about a week ago. We wanted a detailed cleaning of our Mazda. In the end they didn't do a good job. When we got in it was still dirty inside. I'm definitely not bringing my other car here. I'll be doing it myself

Paid for the inside and outside clean. When I was told my vehicle was cleaned, I got in to find a mess. I spoke to the manager and was told to get back in line to get it redone. I was then told AGAIN that my vehicle was cleaned only to find a mess again. I showed the cleaners that I could just swipe my finger to clean off dust. He then proceeded to wipe down my leather seats with tire shine to make it “clean”. My car is now a shiny oily mess now. Plain and simple I will not be back to this place. It truly is SAD to see a grown man put such little effort into something. I would not recommend anyone using their service.

As a small-time car flipper/auto broker this is another company that I have spent thousands of dollars with monthly throughout the years. Things used to be really good here and rapidly went downhill with inconsistent performance and job quality. I pulled in today 1-2-26 and asked if I could pay a little more to get the service that I used to get as far as the interior goes mainly. The manager acted completely unconcerned about anything that I asked and told me it was what it was. And after I asked again could I just pay more, he said that there were no other services available and I understood so I asked could I just start getting the service quality that I used to get and he practically Shrugged his shoulders held his hands out and then walked off. I've been going here literally for years and today was my last day going. I pulled off and I will never spend a dollar there again

Warmly greeted by the lady up front. Price is high but not crazy. 30 to $35 for a hand wash and cleaning out the inside.. The car is hand washed two people working on it as it goes through. There's a great little seating area outside with some Adirondack chairs and a nice lobby room inside where you can relax at work and have a Coke or whatever.. The quality was 7 out of 10. Definitely look better than it did going in but definitely some spots that were missed on the windows and inside and things. Don't forget to tip the guys outside.

This is what happens at Synergy Auto Wash, in Halls Tennessee. Yes these are deep scratches on my Chevy Tahoe. When brought to their attention, denied all responsibility and would do nothing to make it right. It’s evident their brush was the culprit as the deep scratches on the hood and roof represent . However they would offer A 100 dollars worth of washes I don’t think my pocket book can justify continued destruction!!

Very good service. I like the washing to avoid the scratches of the machine washes. Team completed hand drying quickly and efficiently. I wiped off the door jams myself after to put the finishing touches on the truck. Looking like new. 01/14/26 took the car for a quick wash. They did an excellent job. Very pleased.
