Amanda took great care of my car. Excellent customer service and such a friendly face. Will definitely be coming back thanks to her! She deserves a raise!
Amanda was freaking awesome! I brought in my EXTREMELY DIRTY car after Burning Man and man…did she take care of me & my car :) Honestly couldn’t have asked for a better experience getting my car cleaned. If I could give more than 5 stars I would. She welcomed me and helped me pick what kind of wash to get to get Sheila (the car) cleaned. And she did a great job.
i didnt even know you could have a good time at the car wash. amanda showed me otherwise.
This little gem is nicely hidden between MLKjr Blvd & Grand (Union & Grand for older folks like me) on SE Clay St. Don't let it's size fool you! This carwash is tiny but mighty! The agent taped my rear wiper to the window and I was thinking oh that won't be necessary. I'm glad I didn't say that out loud! This little place has a lot of power! I felt like the windows were gonna get blown out when I went through the dryer. My ears almost popped! That was an excellent experience. It reminded me of going through the car wash as a kid in the 70s. I had to pull over at the business next door so I could straighten my mirrors. The bugs from last fall are finally gone. The funny thing is that I've gone through the car wash many times since that road trip and still were dragging them around with me. I used to go to the place that starts with K and they are everywhere in the Portland metro area. I got this voucher for a free car wash when I had my oil changed. I didn't think much about it because I was satisfied with where I was getting my car washed. Or so I thought. I was born and raised in Portland, and Washman has been around as far back as I can remember. I'm a believer in being loyal to a business that takes care of you. Guess who has my business now! There is a Washman right down the street from my work that is a little more convenient to get to than this one. I hope the attendants there are as nice as the one was at this location. Thank you for the shine. Next one is on me!!
I brought two extremely dirty cars into this location and was so impressed with the quality of clean. The person who washed them did an incredible job, spending extra time hand washing the dirt and tree sap off. It was just an extra $3 "extra soil" fee on top of the cost of the wash. He even did a second hand wash round, free of charge. The cars turned out just about as well as spending a ton of money at a professional detail shop, but way cheaper here! This is definitely my new go-to spot to wash my cars.

Tiny but mighty—where exceptional hand-washing meets unbeatable value in Portland!
