Cassette Cleaning....

[starquake]

Realised after 9 months of reasonably heavy van use (we've used 1/3 of the use over the previous 5 years) that the toilet cassette could do with a a clean due to calcium deposits...

Is it as simple as thetford duo and done?

Or is there a cheaper funster alternative (white vinegar)?

I take mine to pieces then jet wash the inside, it removes some of the stuff inside but not all of it.

If you use a brush don't leave it inside!

I use a disinfectant each trip to ensure cleansed fully, fill to brim leave for a while and then air dry, works for me

 

[Lenny HB]

I use white wine vinegar mixed with citric acid need to put it in hot.

If its not too bad a dishwasher tablet & hot water works quite well.

The issue with us is the downtime between trips away can be sub one day at this time of year so no need or time for that.

I'll try the dishwasher tab method, thanks Lenny HB and resort to white wine vinegar if doesn't do the trick. Didn't want to spend on detergents when we already have 10l of white wine vinegar and hundreds of dishwasher tabs (thanks costco)

If you use your toothbrush for the tricky bits give it a good rinse after

Shut it you!

Yes, it's another toilet thread (but you'll like this one)

I use coke cola and ice cubes, actually cheap cola is fine but not diet

Should that be shaken or stirred?
Perhaps a thin slice of lemon.

I tried that but got the cassette stuck in the dishwasher !

Citric Acid and hot water...
let it soak overnight, stiff brush and repeat if required..

Critic acid can also be used to descale the Truma Boiler and water system, and many other household items; kettle, coffee machine, iron, etc ..diluted in a spay bottle it makes a good bathroom cleaner..

I tried that but couldn't work out how to turn the dishwasher on

 

[jezport]

Tried the cheap cola and it improves the taste afterwards

Was the dishwasher fitted as standard in the MH or an aftermarket fitting - asking for an envious friend. ???

Actually it needs to be shaken the coke dissolves the timescale and the ice knocks off any solid bits. But,and this is important, do not drink the coke afterwards

Dismantled my C200 Thetford cassette, added lots of citric acid in warm water and soaked everything inside the main body.

Lubed and reassembled and nice and shiny clean for another year.

I took some photos and a video to aid the task when assembling inside.

I also discovered that the level sensor float was still in place, but wouldn’t float due to scale. Citric acid descaled it nicely so floats once again.

This is the blade mechanism retainer:

The float that I thought was lost.

Shiny inside.

Ready for assembly.

After cleaning don’t forget to spray the seals with silicon. I have the special Thetford stuff just because it is a small can and so handy to keep in the van where I can find it again.

What about this? Sorry, could not help myself.....

We've got Thetford C500 cassette and the seal was leaking. Before taking it all apart, I tried a double-dose of the Thetford Cassette Cleaner with hot water, left for 24hrs, but tbh it didn't appear to make any difference.

So it was a case of taking it all apart and just giving it a thorough clean with an old dishwashing brush (thrown away afterwards!), hot water and detergent. I used a little screwdriver to gently remove any scale.

Once sparkling clean, I replaced both seals, sprayed with silicone spray, and put it all back together again - and it works - hubby very impressed!

Btw, when you remove the mechanism by rotating the central round section, I found if you fill the cassette half full of hot water it makes it much easier to turn it.
