Subject: Cool temperature affects of Muriatic Acid and Peroxide

I am currently etching a PCB with 2 parts peroxide to 1 part muriatic
acid. It is cloudy and cool here and I am doing it outside to avoid
the fumes. It seems like it is taking forever. I'm assuming it is the
temperature that is affecting the speed. Has anyone used a crockpot
to warm the solution?
