Calgon 20400 40 oz Powder

I use this mixed in my black water tank of our 5th wheeler. Search GEO method.Sensors work where as before I always had problems.

I expected to receive a brand new box, unopened, and a fresh Calgon smell, for the money paid here on Amazon. What I got is not brand new, unopened, and does not smell fresh, and feel my money was wasted. I just looked on eBay and found a new box, unopened, free shipping, and about half the price!

Think it’s a crazy price for no more than you get

This is the best product with the most uses as any household product in your cabinet. Soak your crusty glass cooking pans overnight with Calgon powder and boiling water and it will look brand new. Mix with stain remover and you can get chocolate stains out of anything. I always soak my feet in it before I give myself a pedicure. Can't live without it!

Was the product I remember using but couldn't find anymore - but just thought it was a bit over priced.

I use the Calgon water softener in combination with salt to clean my silver jewelry. A little expensive, but it goes along way and works like a charm. One Tablespoon of each, in a bowl (flat bottom) lined with tin foil (shiny side up). The jewelry must touch the foil and be totally under the water, and like magic the tarnish is gone.

great price

Calgon works great in the dishwasher, washing machine, etc but your price is about 5 times everywhere else

Calgon helped ensure detergent got rinsed out of my laundry, but disappeared from stores years ago. Happy to find it on Amazon, not happy to find sellers are gouging.
