Countryboy33 Posted May 20, 2012 Share Posted May 20, 2012 There was recently a post about using Bio Washing Fluid in the toilet. I have a Thetford 20 litre Waste tank. How much Bio Washing fluid do I need to put in please ? Link to comment Share on other sites More sharing options...
Wingpete Posted May 20, 2012 Share Posted May 20, 2012 I find 1/2 ltrr sufficient Link to comment Share on other sites More sharing options...
BGD Posted May 20, 2012 Share Posted May 20, 2012 We just put in a generous "glug" (probably about a mugfull) of Lidl's, or Aldi's finest (actually, their cheapest) down the pan and thus into the empty cassette. I also put a couple of capfuls into the flushwater tank thingy. Job done; and no more paying the lunatic prices for Thetford stuff. Of course you never actually save the money, as whilst there you just buy more "slabs" of their uber-cheap but perfectly quaff-able beer instead.

paulmold Posted May 20, 2012 Share Posted May 20, 2012 Yes I agree that Thetford fluids are expensive but you can get 2 litres of toilet fluid from Aldi or Charlies (Welsh borders superstores) for £6.99. The thetford measure is 75ml so you get 26 measures for 6.99 which is roughly 26p per measure. If you buy the cheapest washing liquid around 99p for 1 litre and put in 1/2 litre or even a 'mug-full' of around 1/3 litre thats at least 33p per measure so where's the saving? I thought the bio-liquid was supposed to be a cheap option - am I missing something? Link to comment Share on other sites More sharing options...
colin Posted May 20, 2012 Share Posted May 20, 2012 Towsure and Go Outdoors both offer cheaper alternatives than Thetford. Link to comment Share on other sites More sharing options...
Brambles Posted May 20, 2012 Share Posted May 20, 2012 I find the cheaper fluids work much better than the big name branded stuff. Link to comment Share on other sites More sharing options...
Basil Posted May 20, 2012 Share Posted May 20, 2012 We've tried them all and have always returned to Thetford Blue, we believe it to be the best and worth the extra, besides which it is only £10.99 for 2.5litres at Go Outdoors, so it is not a lot different to the cost of the cheap ones and it does work which is more than you can say for some of the others!

yeti Posted May 20, 2012 Share Posted May 20, 2012 Its not a question of price, it all hinges on the type of sewage system especially if it is a cess pit or septic tank. The chemicals can cause damage to the biological processes in the pits and some sites will not let you use 'toilet blue',this is quite common on some German sites.

derek pringle Posted May 21, 2012 Share Posted May 21, 2012 Hi A couple of weeks ago we bought a Lidl 'special offer' 5ltrs of Formil Bio for £5, actually bought 2. This will be the first time we have not used the Thetford blu but going by the word on this forum we think it will work out much cheaper, not to mention the above stated restrictions if we come across them. good luck derek Link to comment Share on other sites More sharing options...
David Dwight Posted May 21, 2012 Share Posted May 21, 2012 We have used Lidl bio for a year now, We have been buying it in France 3ltr for E2.49 compare that with Thetford blue. Plus lots of small sites will not let you use Thetford blue only bio. I have now got enough to last us a year or more. Another plus for the washing liquid is that it keeps the tank nice and clean.

peterjl Posted May 21, 2012 Share Posted May 21, 2012 Hi How does the Bio manage "nasty niffs" after 2 or 3 days in hot weather? We returned to using Thetford Blu cos, with that product, there is not usually a problem if i cannot empty for 2 or three days, - this was not our experience with the Thetford green product. I usually only wild camp or use basic Aires for a max of 3 days before having a night or two in a full facility site. Outside of campsites you can find Aires or service stations with dump facilities but this is not guaranteed and depends on the country you are in. I know, and have seen, m/homers take their toilet tank off into the bushes but it is not a practice i adopt. Peter Link to comment Share on other sites More sharing options...

Why is that then as Thetford say it is safe to dispose of in all enviorenments? Supposedly the bad chemicals were stopped some years back.

Bas If you read the latest Thetford-europe pdf, they only say Kem Green is safe to empty in all envioroments, they make no such claims for Kem Blu. Our ‘green’ products*, Aqua Kem Green, Aqua Kem Natural and Aqua Rinse (Test ISO 11734) are absolutely safe to empty into a septic tank or other kinds of small biological systems on the camp site. And that’s good to know as more and more camping sites are recommending their guests to use ‘green’ products. Link to comment Share on other sites More sharing options...
Basil Posted May 21, 2012 Share Posted May 21, 2012 Then why did they issue this after claims that Aqua Kem was not safe to empty? See http://www.thetford.com/Portals/0/pdf/Formaldehyde.pdf Bas P.S.

dragonflyer Posted May 22, 2012 Share Posted May 22, 2012 We have tried each of the above products and have decided that different products suit our different types of camping. Weekend festivals/UK sites we use a non formaldehyde product from O'Learys. Violet in colour. If camping in Europe we take ELSAN Green. For this we pay the price - it is also difficult to find, although we did find some at Highbridge Caravans. We also have a spray bottle of dilute pink liquid. Plus gel deodourisers in the small room. We have now acquired 4 of the small bottles which live underneath the tank. We keep them labelled to distinquish them, as overseas sites can be paranoid about non green coloured fluid.

peterjl Posted May 22, 2012 Share Posted May 22, 2012 Hi there have been several allusions to campsites not liking "non green" toilet fluids. I have never experienced this in trips from Portugal/spain in south to Holland in North, france in west to Austria/greece in east. (mostly on ACSI sites) i wondered if it was me not being very observant about signage or is this something new? Peter Link to comment Share on other sites More sharing options...

But that doesn't say that the Blue isn't safe only that the Green is, in my view trying to market to a 'green' agenda market. Bas Link to comment Share on other sites More sharing options...
colin Posted May 22, 2012 Share Posted May 22, 2012 What it implies is that blue doesn't pass ISO 11734, but in other markets Thetford have blue that does and Thetford are happy to say as such! I don't know if european blue has formaldahyde in it as I've not purchased blue for years, but if it has any sugnicant quantity it should be marked on bottle.

WildBill Posted May 23, 2012 Share Posted May 23, 2012 Beware if using the green bio stuff, don't clean the bowl with anything not bio such as detol etc as it kills the good bugs, turns the water black and causes nasty niffs. Link to comment Share on other sites More sharing options...
