Toilet fluid

Agree. Lidl for us. Also it prevents limescale build up in the holding tank which is warmed by the Alde heating!

Re the emptying/cleaning machines ~ had hoped to try this out at Abbey Wood (some months back) but the machine was not working :-(

I know lots of people use the bio tabs but no one I have come across has shown that they do anything only that they seem to work. Until I get evidence from someone who understands the technical aspects I will stick with the real thing. I may be missing out but I prefer to be safe

All I need to know is that they break down solids rtc and that they prevent limescale in the waste cassette

Tried them for the first time this tour. Very impressed.👍

I am not sure what else I could want from a loo cassette "chemical", other than "work". ie, breakdown solids, not cause/allow smells, keep the cassette clean and be suitable for going into sewage systems mains, cess-pits or septic tanks, plus not costing much?

In our case we only ask for it to keep things in order for 24 hours between emptying, as we camp away from WCs and I have to limit the weight I lift. We are not seeking long term performance with all the added biological challenges that brings, easier to side step that and empty it.

Got that all from laundry liquid for a good few years now, not something I found I got from the proprietary stuff used back then, scale was a real issue.

scale was a real issue.

Not just me then! 

yes. the main differences from proprietry products were two fold...

no nasty chemical smell and a gradual eradication of limescale which, to be fair, does take about 5 Cycles or so...

oh, forgot......price

I removed limescale with white vinegar and no build up since.

So do you drop a sachet/capsule in the header tank and then flush it through or only in the waste tank?
