Thetford - Duo Tank Cleaner Concentrated

This Duo Tank Cleaner from Thetford is ideal for cleaning your holding tank. You use this cleaner for both the grey water tank and the holding tank to free them of limescale, caked-on dirt and grease residue. It is easy to use. There is no need to scrub, so nothing gets damaged. The liquid dissolves the dirt and deposits by itself. Let the cleaner soak in for a while, which also thoroughly cleans the technical parts in the tank. Using Duo Tank Cleaner extends the life of your tank. The concentrated formula makes for a smaller package. As a result, it takes up less space in your cleaning cabinet. For best results, use the cleaner 2-3 times a year.
