I use them a lot and buy them in packs of 6 from Amazon. I use them in the washing machine in every wash so reducing the amount of washing liquid used and preventing the build up of limescale. I also soak stained clothing in them, must learn where my mouth is. I use them to clean the glass oven door.
I’ve used them in every wash, ever since I stopped using pods and conditioner.
A very hot empty cycle with just soda crystals showed just how much horrible gunk had built up in my machine, courtesy of those pods and conditioner. It took a 2nd hot wash to clear it all.
I use just powder now, in a cardboard carton (no plastic) and a lot less than I once did,
