I found the FB page you mentioned. It seems weird that they would keep that separate from their website...hard to see what they carry! I'm assuming all the pictures they post saying "NOW IN STOCK" are all that they carry.
My next place to try out is Hammerly and BW8. There's a coin wash just east of the beltway about a half mile. I don't hang around too long at the coin-op wash! In fact, I left in such a rush last time that I left my wheel cleaner and brushes there! Hoping my mystery box that comes in today has a brush or two in it! Haha I like that, "pay and spray"!
It's an older building on a fairly small lot. Also, it's filled with tons of old people so there isn't really a demand for a dedicated wash area. If there was, I'm sure I'd be taking all their money!
I'm just happy that my waffle weave towel cuts down my drying time significantly! Wheels do take a while, do you think waterless wash would work on slightly dirty wheels? Or what about using a wheel cleaner but rinsing with maybe a spray bottle with water?
If I find a good coin-op wash in the area I will let you know!
