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
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.
