Thetford 202196/0619 Aqua Kem Blue Toilet Sachets, Blue, 375g (15 x 25 g)

Excellent product, easy to use and economical. I was a bit sceptical at first due to the size of the sachets but I’ve used them several times now and can say without doubt that they work really well and keep the tank smelling fresh for longer than the liquid. Another factor is they are pre measured so just one sachet, with the liquids I usually just guess and end up using more than needed.

Just re-ordered, been using these sachets after I ran out of fluid and needed something quickly. Will not be going back to fluid, these are really good and keep the toilet smelling fresh and seem to last longer than the fluid. A very effective and convenient way of adding chemical to the RV toilet.

Always use this product, it’s so good and easy to use

These are very convenient to use and ensure you get just the right amount of chemical in your loo tank. My only criticism is the jar they come in is a bit of a waste of plastic, although it is recyclable.

Does it's job when it's in the poop. Relatively expensive though.

So much less faff than the liquid. Nice and easy to store, chuck one in the cassette once emptied, add a bit of water & good to go. Fresh smell, breaks everything down as it should & no mess.

After years of using the traditional blue toilet fluids I thought that I would give these a try. They are so convenient to store and use. I keep the tub under the sink in the toilet of the caravan and just pop one into the toilet cassette though the flap after each emptying, it helps to leave a bit of clean water in after rinsing the waste out to aid dissolving the sachet. There is no more messing about with the measuring cups and ending up with blue dye on your hands. In use they have been great and there are no nasty toilet smells in between emptying sessions although for clarity, we don't use the toilet for solids. They do work out more expensive than the blue fluids but I think that its worth paying the extra for the convenience factor.

Easy to use and does the job perfectly

Solito prodotto disgregante che fa ottimamente il suo lavoro. Molto soddisfatto

Son bastante más efectivos que los liquidos, una vez probado no creo volver a usar los garrafones de 5 litros

dissout les papier et matière fécale

Sehr gutes Mittel - hatte ein anderes blieben immer Krümmel übrig. Dieses löst sich vollständig auf und wirkt gut geruchshemmend

Works as indicated. Best black water tank digester I have ever used. No bad smells and no plugs. Make sure you always use enough water to allow it to work it’s magic.
