Another toilet question (I swear I’m not obsessed with toilets). We are de-winterizing and I found what looks like black mold in the toilet? What’s the best way to get it off so it doesn’t come back?
Just clean it with a little diluted bleach. Contrary to what many say, a little bit of bleach diluted with water wont hurt the system or seals. Or just clean it with vinegar if you’re worried about bleach. A little surface mold is nothing to worry about.
I’d mix 1/4 cup of bleach with 15 gallons of water, dump it in your toilet, and let it drain into the black tank. This should also help kill any mold spores that may have formed in the piping or black tank.
And since it sounds like this happened over winter, there be moisture issues in your RV while it’s in storage. Next time you store it over winter, place some Damp Rid throughout your RV to help absorb excess moisture.
