Elsan Fresh 2 Waste Water Tank Additive, Grey, 2 Litre

This works really well and we have tried a few.

Would be easier if the lid were the measuring guide rather than the side of the bottle. On the side of the bottle is great to see how much you have left, but you need to be mindful when pouring directly from the bottle. I am scent/chemically sensitive so I feel it has quite a strong scent and notice when it has first gone in. My husband loves the scent and It is not unpleasant, just strong - I am just worried I might develop a migraine from it - which wouldn't be the best way to start a trip away - but, so far, that hasn't been an issue. Will definitely continue to buy and use it.

Flushed down the waste tank and loads of bits flushed out. Seems to be cleaner than before. I would buy use again.

Works well to flush smells

Great stuff Use it on our boat on both toilets after tanks have been emptied. Seems to be keeping the system clean and fresh. Expensive stuff that

I have used this grey tank cleaner and deodorant before, it's the best product on the market. Breaks down fat etc in the waste tank on my motorhome, that fouls the level sensor and prevents it working and stops drain smells from filtering back up waste pipes. Would recommend this product from this supplier. Comes well package, with a fast delivery.

Does the job, keeps all clean

Used on motorhome and easy to do although waiting to see if it has freed up the level guage in tank. All smells a lot better now!
