Waterproofing overspray

Is there any quick and easy substance for removing waterproofing overspray

I’ve used Oil-Flo when it was on glass. Takes a little elbow grease but works well.

I tried oil-flo Tony, didn’t budge it, even with steel wool, also tWS remover, and wd40,
Going to try oven cleaner next , see what happens

My mistake, I was thinking masonry sealer over spray. Are you dealing w/ the black stuff?
One word of caution about the oven cleaner - don’t let it sit on the frames or it can seep into the IG seal and cause them to fail.
