No one likes the dirty jobs... If you are a seasoned camper they are part of the lifestyle but probably the least fun. In our campervan they all seem to be a "blue" job too, definitely not "pink".

This week we review a grey waste and cassette toilet cleaner that does both from the same bottle. Thetford Duo Tank Cleaner literally does what it says on the bottle. Not something we have used before but we do trust the brand and this stuff is excellent, just the job - so join us as we explain why and how to use it.

Lets us know in the comments below what you use to clean your grey waste tanks and any good tips.
