Which grey/waste tank cleaner - votes please (1 Viewer)

[Winger]

The branded thetford stuff is the only stuff that stops any rancid smell.
We've tried every option, coke, washing power, but the smell can still be awful when empting.
Its not a huge expense, a small amount capful every few tanks, and no smell when emptying. We use less than the recommended dose.

(We have traps so never have internal smells, but I don't like leaving a stink bomb at disposal points - though seems I'm in the minority on this! Mines electric dump too so I don't even need to be near it, but still.....)

Citric acid is a natural, weak organic acid that is found in many fruits and vegetables, especially citrus. It is the most widely used organic acidulate across all industries because it Taurine (3).

I see above people using citric acid in their boilers. I assume there is no detrimental effect to the innards?
If using the powder what ratio of powder to water please?

Thanks

Thanks for this advice. These chemicals are so expensive and it’s good to hear a solid recommendation.

I agree - we use it now for all our trips, and we have had a couple of longer trips, 60+ days, works well. We do take a couple of bottles with us to last - not always easy to buy in some countries.

White vinegar. Cheaper than chips (certainly in France) and no smell or sugar. Pop a litre down the drains now and again. Drive around, then dump (in a designated drain of course). At the end of each big trip, a couple of litres in the main tank and run through the boiler and pump and aftwards run a half tank of clean water. No smells, no calcification.

I just bought some: 39p for 500ml in Lidl

We used to use a couple of the largest bottles of dilute orange juice just add a bit of water to it, a good slosh around and leave for a couple of days and flush out. Another one we use regularly now is 3 or 4 steradent tablets into the full fresh water tank drive it all thru into the grey tank leave a few hours flush it all thru.

This is what I use. It works brilliantly, killing two birds with one stone! Great washing up liquid, with a lovely smell, plus it cleans the pipes and keeps the waste tank smelling fresh.
I already use a Qualkem product for cleaning and soaking my brass instrument, so I know it's a good make, and their products work
