Re: Composting Toilets vs. Holding Tank
Skid marks? Use a bigger bowl under the seat, or larger coffee filters. Isn't that why they use them?
Actually ToTo, a major Japanese supplier of toilets, invested a lot of money into special porcelain surfacing so that nothing sticks to their bowls. There are indeed folks who spend all of their time working on these issues.
