Dual action. Formaldehyde-free. Easy to use.
Fenwick’s Top & Tail is a dual-action toilet fluid for caravan, motorhome and portable chemical toilets. It can be used in both the flush-water tank and waste tank, helping keep the toilet fresh while breaking down waste and controlling unpleasant odours.
The biodegradable formula contains lubricating agents that help care for rubber seals and the toilet shutter. Slip agents also coat the bowl, helping waste rinse away more easily with each flush.

How to Use
Flush-water tank: Add 50ml of Top & Tail to the flush-water compartment, then fill the tank with water.
Waste tank: Prime the tank with 2 litres of water, then add 125ml of Top & Tail for every 20 litres of tank capacity.
Dispose of the contents at an approved disposal point or through the mains sewer where permitted.
When changing from a formaldehyde-based treatment, clean the toilet cassette thoroughly with Fenwick’s Waste Pipe & Tank Cleaner first. Residual formaldehyde can prevent Top & Tail from working effectively. Regular monthly cleaning can also help maintain the performance of the toilet system.
Always follow the instructions on the container.
Why Choose Fenwick’s Top & Tail Toilet Fluid 2.5L?
Fenwick’s Top & Tail simplifies chemical-toilet maintenance by treating both tanks with one product. Unlike a flush-water-only rinse, it also helps break down waste in the cassette while supporting seals and moving parts.
Our Thoughts
This is a practical option for caravan and motorhome owners who prefer one treatment for both sides of their toilet system. The large 2.5L container is economical for regular touring and provides up to 20 measured waste-tank treatments.
