Hi!
I've got a cold 4/3500 washer and have been asked to bid on cleaning an asphalt parking lot at a doggy daycare business. The owners have it caged off, about 2000 sq ft. There's a small area they have covered with gravel that will be removed before I get there. The lot was sealed in the last year or two. There's no greas spots that I could see, course I couldn't see below the gravel.
Anyhow, I've searched the archives on asphalt cleaning which has yielded:
- don't use degreasers, they also dissolve asphalt (although over the counter asphalt cleaners have them)
- asphalt is soft, so don't use anything that will streak or damage it (no close wand, no circular cleaner, turbo maybe at a distance)
- check with the authorities about runoff regulations
- caustics might work
So I'm thinking spray on some TSP, let it dwell and rinse off with a distant wand or turbo. Like maybe a 40 wand high enough not to stripe. But I've got a dirt killer turbo too.
It's likely to be in the forties when I do this.
Oh! Dog crap stains? I would think they would come off easy, but if not I could spray on an enzyme stain remover, which would eat the organic stuff and not touch the petro based asphalt.
Suggestions?
