What cleaner will take auto wax off black plastic trim without damaging the finish?
Try a good eraser. I know the pink ones work.
The optimal thing is wipe up any spills or drips immediately and clean the area with dish soap and water before the paint has a chance to dry. On dry paint your results may differ based on the length of time the paint has been on your floor, and of course, the amount. The type of finish on your hardwood floor also factors in. You should get the best results with a product called "Goof-Off"…
Yes you can as long as you are not concerned about damaging the underlying floor. If the floor is old and the finish in unimportant to you, you are fine. If you are looking at steam cleaning an area rug which is on a hardwood floor, that's a definite no-no and the as the water and steam can stain or buckle the hardwood.
