Many of us already know how to clean a cassette toilet and you may feel that finding the best caravan toilet cleaner isn’t that important and doesn’t require more than a moments thought.
But when you come to think about it, you will probably buy many gallons of caravan toilet chemicals over time and spend hundreds of pounds. So finding the best chemical for your cassette toilet may be more important thank you first thought.
What is the best Chemical for portable toilets?
There are two main things to consider.
- Does it do a good job of taking away any unpleasant odours.
- How environmentally friendly is it, this includes both the wider environment and your own health
But more about the environmental impact and links with cancer in a bit.
I have always favored the traditional blue in the bottom tank and pink in the top tank.
If you do prefer the blue and pink I have myself tried three different chemicals with surprisingly different results.
Elsan (blue and pink) Chemicals For Caravan Toilets.
- Elsan Blue chemical toilet fluid - 2 litre
- Powerful anti-bacterial formula kills germs and bacteria
- Eliminates unpleasant odours
- Exceed the British Standard BS. 2893:1989
- Non-staining - suitable for all chemical toilets and cassettes
This is the first chemical that I ever purchased with my first ever caravan.
It does a fantastic job. Period. The chemicals are thick and seem to dilute for ever. When I empty the toilet the water is still blue even if the toilet has been used for number twos and smells just as fresh as when it comes out of the bottle.
Note – if you get different results from me then I have to say that I am very generous with the amount of toilet chemicals that I use.
Aldi Caravan Toilet Chemical
I have only ever used the Aldi toilet chemical once for two reasons.
The first is that I wasn’t that impressed by comparison to the Elsan. It seemed to be like comparing cheap orange cordial. The dilution just wasn’t that great and I felt that any financial saving would be counter acted by this.
Secondly, as with most Aldi products, when it’s gone from the middle isle it really has gone. So if you try it and like it you may need to buy in bulk next time you see it.
Elsan Green Caravan Toilet Chemical
- Dissolves waste and removes odours naturally and has delightful mild fragrance
- Dissolves waste and removes odours naturally
- Can be used in both flush and waste tanks
- Biodegradable and free from harsh chemicals
- Encourages the biological decomposition of waste
A game changer for me.
It’s my current favorite topic to talk to other caravan owners about. (I know, I need to get a life!)
The reviews on this are excellent. So I though, “I must give this a go!”
A big advantage is that you can use it in both the cassette and in the top header tank, so you only need to carry one bottle instead of two.
It leaves a fresh apple type smell in the toilet instead of the usual chemical smell (although I do quite like the strong chemical smell if I’m honest)
It seems to do a good job of breaking down everything in the toilet.
The best part is that it is free of some of the nasty chemicals that can harm not just the environment, but also ourselves.
Some toilet cleaners contain Biocide. This is harmful to the environment in the same way that pesticides are.
But it gets worse.
Many toilet chemicals contain Formaldehyde. This can cause us humans many problems if you are exposed to it, the most worrying consequence of Formalderhyde being cancer.
However these can be found in many household products, so don’t worry too much.
The fresh smell, and considering the harm to the environment and to humans, I would be persuaded to use the Green toilet chemicals.
From experience, the better brands such as Thetford and Elsan tend to be better. The best of the elsan Green is that it is not too expensive.
So you can do your bit without having to part with more of your hard earned cash.
