Gel 3-in-1 Water Softener, 750ml

We got the Calgon water softener for the black tank in our camper. I think the recipe is called the Geo Method. Google it. After emptying the black tank put 3 capfuls of Calgon and 3 gallons of water. Let it sit or drive around, then flush out. Seems to be keeping it from smelling, but we only go #1 in ours, and never any toilet paper. Never empty your black tank and let sit completely dry, especially if you go #2 in there. RV tip of the day!

I saw an immediate difference in my washing machine and the items I washed. My whites finally look white again. I could not be happier with this product but unfortunately because of the tariffs and the fact that it came from the UK, I cannot order this again albeit I just got my shipment 4 days ago. This impediment to getting what I want because of a tariff that only benefits a billionaire that will never use this product is making me angry.

The only reason I gave such a low rating is because the description said unscented. This was not true. I have asthma and could not use it because of the perfumes.
