Yeah, they are the bomb. I have a premade one I bought on an Amazon Lightning Deal not expecting much, but it was cheap, so what the hell?
Some of the best dough I've ever spent. I have a big sink in the laundry room where I always wash my hands after doing greasy, dirty work outside and also washing other really dirty stuff. Scum and dirt build up fast, and it has always been a pain to clean with a hand brush. The drill brush and some bartender's friend had it looking practically new in ten minutes.
