Thetford Aqua Rinse Toilet Bowl Spray - 500mL - For Toilets Without Flush Tanks
$21
$13.35
If you use a caravan toilet for more than one night, or for solids, use a proper waste tank additive and empty the cassette at the end of the trip. If it has only been used once over a weekend, still empty it before storing the van. Do not leave waste sitting in the cassette for days or weeks.
For urine-only use, sodium percarbonate style products may not help much with odour. A small dash of white vinegar can be used in the waste cassette tank, not the flush tank, unless your toilet manual specifically allows it. Do not mix vinegar with bleach, formaldehyde chemicals, or unknown toilet chemicals.
Dispose of toilet waste only into a signed dump point, a toilet/sewer point that you are permitted to use, or another approved black-water disposal point. Never empty toilet waste into stormwater drains, roadside gutters, creeks, lakes, or onto the ground.
Toilet waste from portable toilets, cassette toilets and built-in holding tanks is black water. The safest and simplest disposal path is a dedicated dump point. These are designed for RV toilet waste and usually have a rinse tap and a large opening that is easier to use without spills.
If you are staying with friends or family, do not tip cassette waste into a yard drain or stormwater grate. If they are connected to town sewer and you have permission, a normal flushing toilet or proper sewer clean-out may be acceptable. If the property uses a septic system, only dispose of waste there if your additive is septic-safe and the property owner is comfortable with it.
Apps such as WikiCamps and other RV travel apps can help locate nearby dump points before you arrive. Planning this before camp is much easier than searching with a full cassette.
Dump points are suitable for portable toilets, cassette toilets and RV holding tanks. Open the cassette spout over the dump point, use the vent button to control flow, rinse the cassette, rinse the dump point area if needed, and leave the lid closed for the next traveller.
Do not use the drinking-water tap to rinse a cassette. If there is a dedicated rinse hose, use that. If there is no rinse hose, add clean water from your own container, swish carefully, and empty again.
A septic-safe additive is the safest choice if you might need to empty into a septic toilet. The product should clearly say septic-safe. Words such as eco, green or biodegradable are useful, but they are not the same as a septic-safe claim.
Pit toilets are more sensitive because they often have less liquid and rely on slow natural breakdown. Use only correctly diluted septic-safe or sodium percarbonate style additives, and avoid tipping concentrated chemical into a dry pit toilet.
Do not empty cassette toilet waste into a composting toilet. Composting toilets rely on a specific dry composting process and are not a disposal point for chemical toilet waste.
Toilet additives are used to reduce odour, help break down waste, improve rinsing, lubricate seals, and make emptying easier. The right product depends on where you will dispose of the waste.
As a simple rule: choose green/septic-safe additives if you may use septic systems, national park facilities, or smaller private systems. Blue additives can work well where the waste will only go to a normal dump point connected to sewer, but they may not suit septic or sensitive disposal points.
CaravansPlus does not recommend formaldehyde toilet chemicals. Formaldehyde products are harsh on disposal systems and are not the direction most RV users should be heading.
Sodium percarbonate is found in many laundry soakers and can be used by some travellers as a low-cost waste tank additive. It breaks down into oxygen, water and sodium carbonate, but it reacts quickly once wet. That means it may need topping up and should not be added to the flush tank.
For urine-only toilet use, a small dash of white vinegar in the waste cassette can help with odour. Keep it in the waste cassette, not the flush tank, and do not mix it with strong or unknown chemicals.
Some portable toilets have a separate flush tank, while many built-in cassette toilets use the caravan's main fresh-water tank for flushing. If your toilet uses the main fresh-water tank, do not put flush additive into the caravan water tank.
Where a separate flush tank is available, flush tank additives can help coat the bowl, lubricate seals, add fragrance, and improve rinsing. If there is no separate flush tank, use a toilet-safe spray bottle product instead.
Waste tank additives go into the cassette or holding tank. They are the main product for odour control and waste breakdown.
Liquids are easy to measure and mix quickly, but still need some water in the cassette to spread properly. Sachets are pre-measured and convenient. Tablets dissolve more slowly and can suit longer stays. Laundry soaker style products can work for some users, but they need more judgement and are not as convenient as purpose-made toilet products.
You can use ordinary toilet paper in some portable toilets, but fast-dissolving RV toilet tissue is safer for cassette toilets with internal mechanisms. Paper that does not break down can foul the cassette mechanism and make emptying messier.
Keep the cassette level while carrying it to the dump point. That helps keep the mechanism clear and reduces leaks around the cap or spout.
Use a cassette tank cleaner at least once a year, or more often if the toilet is used heavily. It helps remove scale, calcium build-up and stubborn residue without scrubbing inside the tank.
