Hey all,
My friends and I have an inside joke that involves cinderblocks that has been a few years old now. There’s a house under renovations across the street from where I live, and I asked the people doing the renovations if I would be able to have a cinderblock I saw on the front lawn, to which they said I could! (for context, the house hasn’t been sold yet and they were getting rid of them anyway.)
I am literally doing nothing with this cinderblock other than having it as a decorative piece in my apartment for the joke. I have put the cinderblock in my bathtub and sprayed off most of the dirt on the surface, but I was curious as to how I would clean it to get it looking more or less good as new.
Thanks in advance, I’m really excited over this stupid thing lol
Take it to a DIY car-wash, drop a few quarters, and power-wash that sonofabich. Probably cheaper than buying acid or even a brush or whatever.
Awesome! There’s one closeby that’s locally owned, doubt the owner would mind. Only question is if it would damage the cinderblock at all with chipping or whatever.
Step one: soap and water. Step two, a mild acid – you probably have a citric acid based bathroom tile cleaner already or similar. Wrap it in a sacrificial towel or similar and let it soak in that weak acid overnight.
Because you don’t have a driveway/hose, I would try something like the Simple Green “OxySolve” cleaning concentrate (it says it’s for power washers but there are mixing instructions for “manual cleaning”). Most concrete cleaners have some pretty harsh chemicals in them that could damage your bathtub, but the Simple Green stuff seems pretty tame.
