    Having just completed an extended trip we will soon begin the task of making the van shipshape and tidy ready for the next trip..... hopefully very soon.

    How do you clean/disenfect/sanitise your Thetford cassette? Should we treat fresh and waste water tanks similarly?

    Can you fill with bleach solution or other cleaning agent and stand to soak for a while? Is bleach solution harmful to the cassette unit? Advice please.

    Regards, Bryan

    Hi
    I have been told NOT to use bleach it will damage the cassette seals, a pal used bleach and the cassette sweld up, I just use disinfectant with no bleach it cleans and smells better. Pete

    Ps
    For the grey tank I put a couple of 2 ltr bottles of cheap coke in it brings a lot of dirt out.

    I tried the thetford cassette cleaner, and it worked well. I did this because there seemed to be a lot of hard deposits around the inside of the tank, this cleaner did dislodge most of it.

    I guess I would only do this after an extended trip, normally I just rinse with water and usual toilet fluid.

    I agree with Peter....bleach should not be used.

    Half fill with very Hot water and a 1/4 cup of dishwasher powder, give it a good shake for a few minutes.
    Empty out and rinse.

    Should be spotless inside..

    I believe Thetford do their own cleaner but they also say you can fill up with warm water and add 400g of bicarbonate of soda and leave 24 hrs works on grey tanks as well, Havn't tried it yet as ours is in use every day, as for fresh water tanks we just fill up and add white vinegar for the same time this also helps descale the boiler.
    Bleach is a definite no no, it can destroy the seals as well as make the plastic brittle and in some cases turn the white plastic brown, not only this but it can cause some chemicals to leach out of the water hose used in most conversions

    I use Thetford Cassette Cleaner which works well although sometimes requires a second application.

    I also give it a brush out with Joyce's tooth brush but please don't tell her as she may not approve.:Wink:

    A quick swish out with water and leave a bit of blue in.

    If limescale builds up in there, take it outside, empty it and add a couple of pints of cheap vinegar and some warm water. Leave overnight outside. (don't forget it is not in the usual place though if you get up for a tiddle!)

    Buy a spare cassette then you can rotate them.

    Have one spotlessly clean and the other full of sewage.

    Thetford cassette

    We use water and a drop of blue. Bio washing detergent worked very well in our waste water tank. It was draining very slowly - now it rushes out.

    Thanks for all the tips, sure one of them will do the trick. Consensus seems to be that bleach is a big no, no. Glad I asked cos that was going to be my first option:Doh:

    I've never even emptied it:Blush: but I've seen what Ralph does.
    But , we use the proper blue stuff , made for the cassettes .
    Ralph just tips everything out. Puts water in shakes it about bit. Empties that.
    Puts some more blue stuff in and shoves it back in the door at the back of the loo.
    It doesn't smell , and we empty it every day. Even if there are just the two of us away in the van.
    AND yes we do poo in our loo:Laughing:

    We use bio washing liquid whilst away rather than the "proper stuff". I empty and rinse the cassette every day. I usually use a garden hose on the cassette after every trip but that isn't guaranteed to shift everything from the nooks and crannies in the opening/closing mechanism.

    Today, after returning from a two week trip I hosed it out as usual then took off the seal &c so that I could clean all those parts with toilet wipes and get inside to use wipes on the mechanism. Once I had put it back together I poured a bucket of hot water into it with a (large Lidl bottle) cap full of bio washing liquid. I then gave it a good shake and emptied it before rinsing with the hose again.

    Seems to be clean now :Smile:

    I don't even know how to empty it.

    It's not my department.

    Once a year we clean both our cassettes with Thetford cassette cleaner and then spray the seals with Thetford silicone spray-it works :thumb:
