We had our bathroom ceiling fixed a while ago, and the guy who fixed it also repainted it, and after that, little paint stains were left all over the bathroom (on floor / grout, on metal towel racks, etc.). What would be the best way to remove them? Is there a household solvent that can be used for this, without needing to buy paint remover? The guy brought his own paint, so I don't know what kind of paint it was, but probably whatever is typically used to paint a bathroom ceiling. Thanks for your help.
