  1. We bought a Unique toilet cleaner for our RV because the toilet cleaner seems to use more natural ingredients and kept things fresh. So far I haven’t noticed any discoloring or damage. It leaves the bowl clean, and the seal obviously lubricated. I think this will help the longevity of our the toilet in my new RV, an investment worth preserving.
