Rain Tunnel Express Car Wash

Affordable and awesome! I took my truck to this car wash. I paid the $ 10 and went for the premium (basic option is $ 6). I was very pleased with the outcome. My truck is very clean and all the salt from the road is gone! There was a line but it goes so quickly. Don’t be intimidated by the line. The wait time is nothing. They run this place well. Thank you! I will be going back here for future washes.

I won’t be going back. I went to the Rain Tunnel on Watson Rd. and it bent my front license plate and broke the holder. When I was doing a search on nearby car washes, I saw a review on another site with the same thing. I just figured it was a fluke, but apparently not. I’m sure it depends on the type of car because a friend said she takes hers there. I took a Toyota corolla. Other automatic car washes have not done this.

$ 5 for a good wash. Accepts credit cards so it’s a simple swipe and drive.
Too complex of a wash to be open ²⁴⁄₇ without supervision though. «Brushless» doesn’t mean touchless. It means soft cloth rotary machines scrub your car.

I happened to find myself in the Sunset Hills /​Affton area the other day and was in desperate need of a car wash. I typically try to go to my dealer for that, since they have a free wash for customers, but it isn’t very convenient for me to trek down to SoCo every time I need a car wash.
That said, while looking for a gas station with a car wash that didn’t have an obscene line, I spied Rain Tunnel Express and pulled a hard left. This is one of those car washes where you put your car in N, lift your foot off of the break and let the wash do the work.
Greeted with the choice of either a $ 5 and $ 10 wash, I opted to go for the premium job since it included a RainX equivalent and a full undercarriage wash. Being a wonderful combination of a brush and brushless car wash, the Insight came out looking super sparkly after going in covered top to bottom in that salty grime that you can only get after driving around in the snow for a few weeks.
This is by far the best automated car wash I have had in a very long time and I would absolutely recommend it to anyone needing to shine up their automobile.
