Affresh W10549846 Washing Machine Cleaner, 5 Tablets, White, 5 Count (3-Pack)

Did a great job cleaning out my washer but left a white powder stuck to the walls of the washer drum. I spent 15 minutes washing this Crap off so it wouldn't ruin any clothes put onto the washing machine.It didn't mention any of this in there add.Maybe it should to be more "Honest" with there product to the consumers buying it.Thank you.P.S. I will never purchase this product ever again because it's to much trouble!
