The Aqua Kem Blue Concentrate is a powerful and easy to use toilet fluid for the waste holding tank which offers the best performance for your Cassette or Portable Toilet. Compared to the original Aqua Kem Blue, this concentrated fluid has improved liquefication for easier tank emptying and stronger reduction of gas build-up. Thetford has kept familiar features from the original Aqua Kem Blue including the number of dosages and the universally loved fragrances.

The odour control performance of Aqua Kem Blue Concentrated products is at the same outstanding level as the original product range. This fluid is 2 and 1/2 times more concentrated - a standard 150 ml dose of our original Aqua Kem Blue worked well for up to 5 days, now only 60ml of Aqua Kem Blue Concentrated is required for the same period of use. A 780mL bottle offers up to 13 dosages for 65 days of use, the same as a 2L bottle of Aqua Kem Blue. This means the new Concentrated product range will deliver more power per drop in comparison with the original Aqua Kem Blue.
