I use the home brand one - apparently the woolworths one is best suited for the toilet cassette. Something about one of the additives which the home brands don't have in them!

John,

we tried premixing once.

Filled a plastic bottle with napisan and water and put half into the empty toilet, all good And we had some premixed for top ups if needed.

We then travelled to our next destination some 4 hours away and when we went into the bathroom the remaining premix was all over the walks and floor. The plastic bottle has exploded, fortunately no ome was in the bathroom at the time.

Needeless to say we will never again leave any mixed napisan outside of the toilet.

We have been using the cheap Napisan products for 13yrs now with good results but found only one of them has the higher concern of Sodium Percarbonate being the Woolies Brand and also $2 extra now. I have since purchased a kilo of 100% pure Sodium Percarbonate from a Home Brew shop when passing through Adelaide. I only use a teaspoon of this product as compared to a capful of the cheap Napisan and find it works well at this concern. The price was $14/kilo.

We also have a 2 litre bottle of the Sodium Percarbonate mixed with water for toilet flushing use with a hole in the lid but always make sure it is securely placed. When mixed the combination of the Napisan and water causes a reaction which can cause excessive pressure buildup. So not a good idea to totally seal the container. Using this for flushing stops excess water use which fills the Cassette quicker.

Cheers Kev.

Got to look hard for the sodium per carbonate content, usually in tiny letters, somewhere on the container. As sands mere says, Coles brand has higher pic content.

Neil - that's the one I use - Supreme - works really well, and cheap - in WA you can get it at Red Dot shops as well.

Thanks all for the replies.  Anyone got any more insight to the original question? :)

"I am wondering if you were to premix an amount  of any of the napisan clones in water and then let it sit in plastic bottles till needed, would it tend too lose any of it's effectiveness over some time?"

Thanks

Cheers John

@ John, DO NOT store premixed "Soaker" as alluded to here it will become active as soon as mixed with water not only will it start to lose it's effectiveness, it will explode if kept in a plastic bottle. (from first hand experience).

@ Jacko; use the supplied chemicals , you've paid for it so use it, or keep until you run out of "soaker" in remote area or expensive shopping area.

I also now put 4 teaspoons of dry powder into cassette after emptying - first No.1 will activate.

Glad I re asked. I have a much better understanding now of how it works. (It finally soaked in, lol)

Thanks all.

Cheers, John

We have a small Portypotti , haven't used it yet , still new in the box , it came with 2 small bottles of chemical , should l not bother and just use nappisan
What's the go with nappisan , do you just add some to the waste tank after use and how much .

Don't use it.

Some of the toilet chemicals still contain stuff that is extremely bad for the environment and this has caused many people to ban the emptying of portable toilets into septic systems.

If you use them it can be very difficult to get rid from the inside of the toilet and it can upset the effective use of the sodium percarbonate.

Sodium percarbonate is no danger to septic systems or the general environment. It breaks down to harmless stuff very quickly.

 

Adding the sodium percarbonate dry is fine. A small teaspoon per day is probably excessive. Using more does not do a better job.

 

Cheers,

Peter

 

Ok thanks , l will get some Nappisan or a clone .

 lol DD , cost hasn't even been mentioned 

We use sodium percarbonate because it works better and it is safe for the environment.
It also happens to be cheaper and you can get it almost anywhere.

Cheers,
Peter

Most Napisan users do it to save a quid. We tried using it for a while but went back to the ''real stuff''.

 We use sodium percarbonate because it the best and most environmental chemical at a reasonable price. If you wish to use commercial chemicals made for the potties you can purchase the ''real stuff'' in tablet form - Odour-B-Gone enviro friendly, Waste Cassette Tablets - at $24.30 for 450 - 500 gm. I will stick to using the same chemical in powdered form and not pay someone to compress it into tablets.

When I look at this page is see that a large percentage of the "real stuff" is not very environmentally friendly. Some of the green stuff offered does not have the condemned nasties in them but the chemical waste action is highly suspected of producing them.

By the eway what is the "real" stuff that you use?

We use Peterg green marine products and have found it to be good. It's around $20 for a litre bottle that lasts for 5 uses. You can buy larger bottles that make it more economical.

I think I'll stick with the sodium percarbonate...
