There are various products specifically designed to clean grey water tanks and help stop the nasty smells that can often come out of your plugholes – usually when driving. There are also a plethora of personal remedies available on the internet – cheap cola or orange squash down the plugholes are some of the more ingenious.
While the commercial ‘tank cleaner’ products undoubtedly work, they are expensive and often only work for the time you have them in the tank – smells can quickly return once drained and used again.
The most effective cheap remedy we have found is scented bleach tablets – available for less then 2 Euros for 48 tablets from most French supermarkets:-
These kill any nasty bacteria living in you grey water tank and leave the grey water smelling clean – think the slight chlorine smell of swimming pool water mixed with a hint of eucalyptus!
Simply let one dissolve in a sink full of water before draining into the tank, or alternatively put one into the shower drain like a urinal biscuit and let it dissolve while you shower.
