I need help identifying a red substance i found on some concrete after removing some kitchen cabinets.
I tried to clean it with tissue and water but it only just smudged into the whole floor.
Should I just cover it with the new floor or try to remove/clean it.
If it’s advisable to clean it up then how should I clean it, it seems to spread and smudge except for the first pic where it looks like goo. Come to think of it there could be two different substances, if so, I’m asking about both.
