Screenwash is toxic & flammable! strange but true! Just look on the side of the container it comes in!

As for antifreeze for statics & thetfords, what about good old common or garden table salt.........yes I do know that its toxic in large enough concentrations.... but it wont harm the ceramic toilets or plastic constituants of waste pipes or the "thunder box" bit of the thetford & its considered safe to dospose of down the drains! & as its a naturally occuring substance, its consideredc ecologically sound as well

interesting georgeB,do you have a breakdown of the mix to prevent freezing water?ie.how much salt say for 4 litres of water.i know i use it regular on the drive when it freezes over and it works immediately.

The U bend of a standard household toilet holds about 1 litre of water so I'd use about a heaped tablespoon per litre there, u bend of a sink, about 150 to 200 mls so a level desert spoon should do it.

As for the thetford, well I use the van through the winter & don't put anything in it whilst its in use, based on the fact that whilst the van is in use the heating system is on. I always drain down the water systems & empty the thetford "thunder box" & drain out the water from the flush tank when I leave site , but when it's returned to storage i leave about 500ml of water in the thunderbox with 1 desert spoon of bicarb of soda & the same of ordinary table salt, I leave the flap open so it doesn't stick, the bicarb stops it smelling & the salt stops it freezing, not that it'll do much damage there anyway

Had the Car antifreeze poison discusion on general not so  long ago  , with some  clever dicks saying dip your finger in to  and taste it , if its sweet theres is antifreeze in ! ,  I  pointed out that was dangerous advice  to  put on a forum and  would recommend  that  glycol antifreeze does not get ingested  in any quantity .

Ethylene glycol poisoning is caused by the ingestion of ethylene glycol. Ethylene glycol is most commonly found as the primary ingredient of automobile antifreeze and hydraulic brake fluids. It is a highly toxic, colorless, odorless, almost nonvolatile liquid with a sweet taste. Following ingestion the symptoms of poisoning follow a three step progression starting with intoxication and vomiting, before causing metabolic acidosis, cardiovascular dysfunction, and finally acute kidney failure

Put some  salt down the traps  instead !!!

Thetford have given you blatently the wrong advice. Non toxic and Glycol can not be used in the same sentence. Follow this link for proof, and feel free to return your conclusion to Thetford. http://www.ec.gc.ca/substances/ese/eng/psap/final/ethyleneglycol.cfm

The only assumption I can make on Thetfords comments are that they are giving advice on which type of antifreeze can be used without damaging their appliance, but are not assuming that the un-witting caravanner would then decant the solution down the drain at the end of the winter season! Theoretically you can collect the antifreeze from a thetford cassette at the end of the winter and dispose of it safely, however this is not really practical on a static caravan. The best and safest method is to take a little extra time and a little more effort to rid your system of remaining water, negating the need for antifreeze altogether.

Cheers
