Using a base cleaner is really not necessary unless the base is very dirty or you are going from one kind of wax to another like a cold wax onto a board with warm wax. The materials on that cleaner are fine and won't harm the Ptex. Just be careful of petroleum distallettes and acetone; especially acetone which melts plastics in a hurry!. Unless you rode through a lot of mid, I think a base cleaner is overkill right now. Just wax, scrape, buff and go!
