Thompsons WaterSeal Advanced has been on the market
for a couple of years. The label promises "Easy soap & water
clean-up," the product apparently reformulated so as to comply
with European Union regulations restricting volatiles.

In practice, soap and water cleanup is by no means "easy."
The product contains some sort of wax that repels water
(and I dare say makes it effective on timber.) But what
sort of solvent can actually dissolve this component
so we can clean our brushes for reuse?


I was going to suggest mineral spirits, as it is most used as solvent
for paste waxes, but decided to look further. Thompson's website sucks,
and I could not find MSDS, but here is a link to more clean-up:

For DRIED overspray, they suggest mineral spirits or paint thinner.
