QPQ "ashing" problem
We've had problems with QPQ coated Critter Cutters developing an ashy white powder and we've been looking for a solution. According to the factory the problem is acid from the QPQ coating process leaching out in a powdery crystal form. The solution they suggested is to soak it for 4 hours in a cup of concentrated baking soda + water. We've tried this and it seems to solve the problem.
