Napisan in toilet system

oldbloke · Guru

We have used this for a few weeks. Works out pretty cheap. Super Cheap Auto also sells it in 1 liter bottles as well for measuring out the correct amount. IMO superior to the napisan stuff.

Mine doesnt stink !

An advantage to the "Nappisan" type of cleaner is that it doesn't harm the environment whereas most of the Chemical toilet additives contain harmful additives like Formaldehyde.

Peter_n_Margaret · Guru

My advise is do not use anything unless you know what it is, chemically, and know the effect of those chemicals.
Many of the commercial offerings are not accurately identified. I view that with utmost suspicion .
We use sodium percarbonate (the Nappysan active ingredient). It is cheap, effective and harmless to septic systems and the environment.
Cheers,
Peter

I had a look at the SCA one online. It says not formaldehyde, but does not say what the chemical is. It does not say "septic safe", so I will stay with the sodium percobonate. It does the job fine.

I guess black tanks can be different to cartridge type ? Am surprised how good black tank pumps out ! Even with all the paper ! Found out the hard way !!! DONT put hand cleaning cloth in there !! Often put essential oil , rose or eucalyptus oil . It covers solution as much as covering smells !!

Absolutely! I also looked and could not find a "materials safety data sheet" for it.

Stick with sodium percarbonate - Safeway "Clean Boost" at $3.50/kg in the laundry section.

All these napisan fans, have you actually tried any of the alternative. We used it for nearly five years. Yes, it does the job. But some do it better, including the SCA. And still very cheap.

It's not on their Web site so I have requested they email a SDS.

Errrr... sodium percarbonate breaks the solids down to a liquid slurry quite effectively whilst causing zero environmental issues... what more do you want to do with a bucket of sh!t?

Are We Lost · Guru

I am a sodium percorbaonate user and believe in the old Mortein motto "When you're on a good thing stick to it". But, I think it is positive that oldbloke requested further information on the SCA product. Maybe the answer will show that we have been ignoring a good product.

Sorry for going off topic, but just a comment about SOG systems.

The whole concept of this system is to draw oxygen into and through the canister when in use and without chemicals.

The oxygen activates the contents as would "Napisan" or other chemical additives.

The SOG system is far more efficient. And when disposing of the contents the "smell" is the same or less than the chemical versions.

When in use there is no internal smell as it is extracted to exterior.

This system will no doubt be the standard in the coming future by van manufacturers.

IMO the SCA is better at converting the solids including paper to liquid. Just 1 dose needed. The sodium percarbonate system still smells and SCA doesn't, well much less so. SCA does not use formaldehyde.

I now use beer bottle cleaner which is pure sodium percarbonate, not the 15-30% of the Napisan type products. More expensive, but I use 1/3 and have less to carry. Cost works out about the same. That reminds me - I need some more.

Hi Nevd

I would also like to know, where you buy it

Peter_n_Margaret · Guru

On line or brewing shops.
Cheers,
Peter

oldbloke · Guru

Will ask next week when I drop into the Home brew shop

Tony Bev · Guru

Thanks for that Peter (Peter n Margaret)

I found some on Ebay, and will look at getting some, when I have used up the napisan stuff, in storage

Thanks for that tip Nevd. I had a look online at a local kit brewer and they had 3 sizes available. It works out slightly dearer per dose than "no name" Napisan (32% active ingredient at Coles), but the difference is negligible. I wonder what else is in the nappy product and whether it's good or bad. I plan to get some when passing.

It seems to me that the thread is focused on keeping and storing Blackwater AND minimising odour. If I cannot access a dump point, I rely on Sodium Percarbonate ($10 a Kilo from Home Brew) and a well maintained seal in the Porta Pottie. If I can reliably access a dump point inside 3 days, I have started not using any additives at all. The afore mentioned seal on the Porta Pottie is quite effective and the odour encountered when the cassette is opened is no worse than that of a long drop. If I have to store Blackwater, I have found that Sodium Percarbonate application starting on day two is sufficient to kick off a bit more decomposition in the cassette contents. So, in essence, I have gone from using the foul smelling propriety agents to regular doses of Sodium Percarbonate, to nothing if it is not needed. The cost savings of my current practice are not that great but it all helps towards a few more kilometres in the tank.

I would still use the stuff even if emptying the next day. The emptying process is a lot better if it's a soupy slurry with minimal odour compared to ......not using anything.

Peter_n_Margaret · Guru

We have recently been using a different method of use for our cassette toilet, more or less forced on us through the lack of dump points and ground that is too hard to dig holes in.
We put urine into the grey water tank and minimise flush water into the cassette.
The result is that emptying the cassette goes from 3-4 days to at least a week.
We also found that we needed a lot less sodium percarbonate and the cassette smells were very much reduced.
Down sides were that we need to take care that the grey did not send smells back up the pipes and that it was emptied more often, but that is relatively easy to achieve.
The cassette also needed a better rinse when emptying.

All in all a pretty good result and I will install a permanent urine tank when I get home.
Cheers,
Peter

Have you also used Napisan in a grey water tank, to remove grease residue?

Are We Lost · Guru

Oldbloke, now that this thread has been revived, you asked SCA for more information on their toilet chemical 6 months ago. What is in it?

SCA still just says "Formaldehyde free". But what appears to be the same product (based on colour and "formaldehyde free") is sold as Portasol by BCF and Bunnings. From the label I found the active ingredients are:

2g/L Glutaraldehyde which is an antibacterial used for sterilisation.
6g/L Quarternary Ammonium which appears to do a similar job

What this means for the environment I will leave to others, but it does not sound positive to me. Dumping in a septic system would clearly be out as it would be likely to kill the good bacteria.

Sorry Cruzin, not ignoring your question but I have no input to that question.

We bought a 5L bottle of ALDI Portable Toilet Cleaner on special for about $20.
We used it on 3 trips before Covid-19 arrived, it worked exactly like the Thetford product except that it has a eucalyptus aroma.
We usually don't shop at ALDI, wish I'd bought 2 or 3 bottles.

So thinking mischievously, how are getting urine into the grey water tank? Has your shower become a second toilet or the Number One toilet? biggrin

Not difficult. You pee into a container and pour it down the bathroom sink.

Why wouldn't you use a tree outside rather than contain it?
