Our plastic red hazard stakes have a white, hard water film on them that we are trying to get off but can't seem to find a way. We have tried sanding, pressure washer, and scrubbing with no success. I have thought about vinyl guard but we have over 250 hazard stakes and i don't want to spend the next two months with a heat gun in my hand. Next thought is a wood plainer.
What do you think?
