Nappy soaker is a widely used alternative to toilet chemicals, probably every second van uses it.

Resist the temptation to use other additives that can harm septic Dump points.

Your home toilet doesn't use additives in flush water, neither does a port pot.

Yes I agree we have never used chemicals containing formaldehyde and living in the country we are mindful of keeping the septic enzymes in a good balance. We will look into the nappy soaker as an alternative as it does contain some extra ingredients than the lectric inwash and soaker washing soda we are currently trialling. hanks for the feedback

Thanks Tony and Bev, we are trialling the Letric brand i looked for the MDS but was unsuccessful however I did find an information sheet and it states it is 100% sodium percarbonate, below is from https://lectric.com.au/pages/faq, my only question would be is the laundry soaker and washing soda the same although the main ingredient is sodium percarbonate.

What is Lectric Washing Soda made of?
Lectric Washing Soda is made from 100% sodium carbonate. It is all natural, with no phosphates, dyes, fragrance or colourants

While searching the web for an alternative toilet chemical I came across an article written by Ian Jenkins a retired Professor of Chemistry and is now Professor Emeritus at Griffith University where he refers to The use of Sodium Percarbonate in Portable Camping. Toilets

I personally have used both the Vanish and the Woolworth brand Ultra Booster Everyday Plus Laundry Soaker with excellent results. Its worth opening the Attachment where Ian explains his reasons in more detail.

 

Ian says. Ultra Booster Everyday Plus Laundry Soaker, Nappy Treatment Plus, Laundry Soaker and Inwash Booster, or various similar products available from the major supermarket chains; all contain between 280 and 346g/kg of sodium percarbonate, are made in Australia from local and imported ingredients, and are generally labelled safe for septic tanks for the past 5 years and have found it to give excellent results. You can also use Vanish

 

When purchasing read the label carefully (the supermarkets sometimes change the name of the product or what is on the label, and the contents are often in very small print). Look for the amount of sodium percarbonate (>300g/kg, is best), safe for septic tanks and surfactants are biodegradable.

 

Instructions: Add 2 level tablespoons (1 level cap-full) of sodium percarbonate (Ultra Booster Everyday Plus Laundry Soaker, or equivalent) to one litre of water, stir for a few minutes then pour into lower tank of portable toilet (20 lit capacity). Wash any undissolved powder into the tank with a further one litre (4 cups) of water. I also dissolve 1 level tablespoon of sodium percarbonate in the water in the flush tank (9 lit). As with all chemicals, keep out of reach of children and avoid contact with skin, and eyes in particular. Never mix other chemicals with it.
