Dometic cassette

Open the top section www.youtube.com/watch spray all float componentry and seal with silicon spray re- assemble and put some Thetford Blue (Mixed) in tank to keep it fresh www.thetford-europe.com/au/en-AU/products/toilet-care-products/waste-holding-tank-products

I put silicone grease (not spray) on the seal once every 5 or 6 years.
Empty it after the last use, rinse and put it back. That is all. No need for complications or expensive 'potions'.
Cheers,
Peter

I use rubber grease on seals, wash cassette out and rinse with Nilodor in the water. Get rubber grease from bearing suppliers and nilodo from Coles.

I use Napisan/Boost when using the cassette

This leaves it very clean, after I empty and rinse it

For storage, (wearing throwaway type light plastic gloves), I put a bit of olive (cooking type) oil, on the seal
