I don't know if the hot tub is the appropiate place for this one, but I will try here first. 
After reading the sucess stories about applying car waxes / sealants to sinks and showers I decided to give it a try..... Wow, what a difference! The sinks look waaay better and are much easier to clean, the faucets look bettter than new, but the top improvement is in the shower glass doors. Day and night!
I used several products in differents places to test them (TWPUG, Mothers cranauba cleaner wax, Eagle one nanowax) and so far after 2 weeks all of them are working as good as day 1 :up
I haven't tried yet the shower walls (ceramic tile), but I think it should work. The place that is getting my attention are the kitchen countertops (formica or similar). Cleaning them gets tough sometimes. I think that a good waxing should help. I don't know however is the material is not affected by car wax in any way.
What do you suggest? Should I do it or no? Cleaner wax or natural carbauba? Wax or sealant?
In case the answer is "yes, go ahead" I am not planning on clay bar, polishing and glazing so save the suggestion of #80 and VM for another time
