Porta-Pak RV Marine Black Holding Tank Deodorizer Drop-Ins, Camper, Boat, Camping Cassette Toilet Cleaner Pods, Lavender Breeze, 10 Pack

Ok, these ARE as good as they say they are. All the reviews are spot on. Ok they are a little pricy but I’m sitting here in my boat and for the first time in a long while I’ve not needed to light an incense stick after using the loo! Yes I’ve tried all the other chemicals available… the problem with my boat is she’s small, 20’, and the loo holding tank is GRP and of a drop through design. You go and it drops straight down through a sprung loaded flap which is not airtight. They’re called Hampden toilets because I assume they were fitted to that classic lil boat, the Hampden 24. Fibre glass holding tanks don’t like harsh or even the organic toilet additives…. Best I’ve found up till now is no fluid additive and spray of lemon kitchen cleaner in the bowl after use and incense sticks…. But sitting here writing reviews on the things I’ve bought I’ve noticed a lovely smell in the boat, I put one of the little sachets in about two hours ago and yes it’s working as promised! Totally awesome! I’ll be using these from now on, it’s worth the expense for this absolutely gorgeous scent that’s now pervading through the boat…. My lass thinks it smells like her Mum’s perfume, something I shan’t be repeating to her mum! But if you are despairing about the nasty niffs from your Campervan WC or the one on the boat, especially in this hot weather we are having, these do work. Trust me on this and always wear sunscreen…..

Perfect. My husband loves overdoing it with the liquid, so this was a perfect alternative to keep costs down and ensure we have enough in stock to use for the caravan toilet

Amazing Product !!!!!!!After 4 years of owning our rv the odour coming from the black holding tank when driving was terrible!!!! Totally had enough and Had to do something ? Bought these drop in sachets after reading reviews!!!!! Omgosh no odour what so ever now !!!!!! Amazing Product will definitely be buying more !!!!!!!!!!! Thank you

It works! Minimal fuss

Great for caravan but quite expensive

The Welex PPRVLAV Porta-PaK Holding Tank pucks work well. This is the second time we have bought this exact pkg to use these pucks the toilet in our RV camper.

Work well with portable loo in caravan no smells

As described

رائع وفعال في النظافه وازاله كل شي

Straf spul, maar te duur voor cassette gebruik in caravan. Dan liever toch aqua gem van thethford.
