Necessity, always the mother of invention. Couldn't find my pastry brush, but saw the kids' paint brushes were in the dish drain. Worked better than any bristle pastry brush I've ever owned. No stray "hairs"!
p.s. I despise silicone brushes for pastry. I find them to be fine for ribs & roasts, but too harsh for delicate pastries. #kitchenhacks
