Fenwicks Top & Tail is an original green, formaldehyde-free, and eco-friendly dual-action toilet fluid. It's suitable for all chemical toilets and designed for both top and bottom tanks. When added to the top tank, it ensures a hygienic and fragrant toilet with every flush. The added slip and lubricating agents keep the toilet functioning perfectly. In the bottom tank, it safely breaks down waste without toxic chemicals and can also be used as a bottom-tank-only product. Using it in the top tank doesn't weaken the bottom tank when flush water is added, making it easy to use and cost-effective. It lubricates rubber seals and shutters in non-mains toilets and coats the bowl to keep it clean and fresh. This toilet fluid adheres to strict environmental policies, containing no highly toxic and carcinogenic formaldehyde. It can be disposed of in the normal sewerage system. With a seven-day cycle, it efficiently breaks down waste, kills germs and bacteria, and has a fresh smell.

To use Fenwicks Top & Tail in the top tank, add 50ml to the flush water compartment and then fill it with water. For the bottom tank, first prime it with 2 litres of water. Then, add 125ml of the fluid for every 20 litres of the bottom tank's capacity. It's safe to dispose of at dedicated points and in the mains sewer. When switching from a formaldehyde-based product, wash the toilet cassette thoroughly with Fenwicks Waste Pipe & Tank Cleaner to kill the formaldehyde, which could stop this fluid from working. Cleaning your toilet once a month with Fenwicks Waste Pipe & Tank Cleaner will help keep it working well.
