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

Smell lovely definitely does what it says no smells through plugholes in kitchen and bathroom even put some in cassette toilet . Arrived quickly good price would buy again.

Always works well for me

Scent could be nicer but it does the job of helping prevent overly-much bacteria in the grey waste.

After having a very hot summer we noticed a smell coming from the waste pipes in our new motorhome. We ordered this freshener and put a little in each plughole... it really works! No more smells!

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.

Works well to flush smells

Used this product as Motorhome waste water emptying had slowed right down. After putting in applicable solution with water, and drove van around to mix it all up in the tank, then leaving for a day or two, tank was emptied. It certainly had the desired effect, as any sludge & other nasties were dissolved and emptied. Very effective product. Supplier delivery was excellent too. Would recommend.

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!
