Description
Thetford® Grey Water Fresh concentrate is an effective liquid that prevents odours from the drains and the grey water tank.
It also reduces the build-up of residue in the grey water tank. It keeps black water fresh for longer.
Add the Grey Water Fresh concentrate directly into the sink or drain and rinse with clean water.
For a 100-litre black water tank, the recommended dose is 80 ml. If the ambient temperature is above 30 °C, the recommended amount is 100 ml.
One dose works for up to five days.
Do not add Grey Water Fresh concentrate to the fresh water tank or the waste tank of a chemical toilet.
Always empty the tank at a designated place and, where possible, rinse it with clean water.
