cleaning - What is the white, crusty, crumbly stuff I find
Nov 24, 2016I just recovered two big 6" chunks of a bouyant, white chalky pipe-blockage from my tank. No, it is not slippery. It feels like one might expect wet chalk to feel, or joint compound that has about 90% of the stickiness removed. There is a bit of black nastiness on the outside, but the inside is surprisingly white for something from a sewer pipe.
