Shower cleaners

Nothing sold commercially...supermarkets...will harm your tanks or seals but I wouldn’t use Comet or comparables on plastic such as shower walls. I do use silicone often on the toilet bowl seals.

You will be fine with any product that is marketed for the purpose.

We use the foaming bubbles stuff sometimes. Most of the time we just wipe it down right after showers. We use liquid sower soaps so there is no residue fro mbar soaps nd all water is filtered so little to no mineralization to ruin things.

RV stores do sell bathroom cleaner. It will not scratch the fiberglass tubs or sinks, and I assume will not hurt anything in the tanks, but not much will if just cleaning.

Vintage tank seals do not like bleach, but newer ones are fine with it. Rubber seals are made better now I guess

Thank you all for your advice.

I don't know what brand your shower is, but here is the cleaning instructions that came with mine.

First: If you have or camp where there is "hard water" invest in a water softener of some type. That's IMHO the first step. It cuts way down on the mineral buildup and PITA to get it off. Helps on the sinks and toilet as well.

Next we use the shower spray you put on the walls after your done that you can rinse off in the next shower. Comes in a pump sprayer bottle, don't recall the name but it is Same as we use in the house.

And then to clean the shower when we return we use the "foaming bubbles" stuff in the areasol can.

When we have a rainy day at a campground, I usually do inside cleaning. I first do the woodwork with liquid gold and then get to the bathrooms. The shower gets cleaned and a coat of paste wax.
