The Solution for Fresh, Odour-Free Caravan Toilets

Cassette and portable toilets pack a complete wastewater system into a very small space. Human waste, toilet paper and urine collect together inside the cassette, where they can quickly create strong odours — particularly in Australia’s warmer conditions.

Urine also contains compounds that can contribute to hard uric scale deposits inside the cassette, valves and toilet system over time.

Traditional toilet chemicals often rely on strong fragrances and chemical treatments to control the problem.

ProPower Cassette & Porta Loo works differently. Instead of simply masking unpleasant smells, it introduces naturally occurring probiotic microbes that help manage waste and odour inside the cassette.

Why cassette toilets smell

Cassette toilets create a challenging environment. Urine, solid waste and toilet paper are held together in a small tank, often in warm conditions.

As waste breaks down, strong odours can develop. Urine can produce particularly sharp ammonia smells, while minerals and urine compounds can contribute to scale deposits inside the cassette and toilet system.

Leaving waste sitting in a cassette for extended periods can make these problems considerably worse.

Simply adding a strong fragrance may hide the smell temporarily, but it doesn’t address the waste inside the tank.

How ProPower Cassette & Porta Loo works

ProPower contains a proprietary blend of probiotic microbes.

Once introduced into the cassette, these beneficial microbes help create a more favourable biological environment and begin working on the organic waste inside the tank.

They help control odour-producing compounds and initiate the breakdown of solid waste while regular treatment helps manage the conditions that contribute to uric scale build-up.

The result is a more naturally managed cassette without relying on harsh chemical treatments or overpowering synthetic fragrances.

Frequently Asked Questions

What is the difference between a cassette toilet and a Porta Loo?

A cassette toilet is usually permanently installed in a caravan or motorhome with a removable waste cassette, while a Porta Loo is a self-contained portable toilet. ProPower is suitable for treating the waste tank in both types.

Why does my caravan cassette toilet smell?

Urine, solid waste and toilet paper are stored together in a small tank where organic waste begins to break down. This can produce strong odours, including the sharp ammonia smell commonly associated with urine.

Does ProPower just cover up toilet smells?

No. ProPower uses probiotic microbes to help manage organic waste and the compounds responsible for unpleasant odours rather than simply covering them with synthetic fragrance.

How much ProPower should I use in a cassette toilet?

For first-time use, add 60ml to the cassette. For regular treatment, add 30ml after each emptying.

When should I add ProPower to the cassette?

Add ProPower after emptying the cassette so the probiotic treatment can begin working as the toilet is used again.

Does ProPower break down solid waste and toilet paper?

ProPower helps initiate the breakdown of organic solid waste inside the cassette. Appropriate toilet paper and regular cassette maintenance should still be used.

What is uric scale?

Uric scale is a hard mineral build-up associated with urine that can develop inside toilet cassettes, valves and wastewater systems. ProPower helps manage the conditions that contribute to this build-up.

Can I use ProPower with other caravan toilet chemicals?

Avoid using bleach, disinfectants and harsh chemical toilet treatments at the same time as ProPower because they can kill or reduce the beneficial probiotic microbes.

Can I switch from a chemical toilet treatment to ProPower?

Yes. Ideally empty and rinse the cassette before starting ProPower, particularly if conventional toilet chemicals have recently been used.

Is ProPower suitable for septic systems?

Yes. ProPower uses beneficial probiotic microbes and is suitable for biological septic and wastewater treatment systems.

Can I use ProPower to clean the toilet and bathroom?

Yes. ProPower can be diluted 1:10 with water and used for cleaning bathroom surfaces.

Do I still need to empty my cassette regularly?

Yes. ProPower helps manage waste and odour but does not remove the need to empty the cassette. Always dispose of cassette toilet waste at an approved dump point or other permitted black-water disposal point.
