Homebrew Rez Block Or Piece Water??

Edit. I am looking if someone knows a homebrew recipe like rez block or piece water.. I know how to clean my glass.. I am looking at prolonging the times between a deep clean.

Just as the title states. Does anyone got some down pat homebrew recipes for their water pipes? ? the buildup on my ash catcher is a bit hard to stay on top of to clean multiple times a week. even with daily water changes. TIA!!
