Frequently Asked Questions

Cleaning and maintenance

Protecting the seals must be foremost in mind when cleaning the RV toilet. Bleach and acids found in most household cleaning products will potentially dry out and damage the seals. Mild organic acids and Citric Acid will not cause harm. The acids generally found in household toilet bowl cleaning products, will dull and pit the bowl surface.

“Non-abrasive” household cleaning products may still be abrasive enough to dull and scratch the RV toilet bowl making it vulnerable to future stains. Thetford® products are specifically developed and tested on RV surfaces and they’re compatible with RV plumbing systems.

Thetford® recommends replacing the lip seal every four to six years, depending on how often the toilet is used. Some suggest treating the seal between the bowl and Cassette® at least twice a year.
