Reckitt's Crown Blue (Blueing tablet) - Pack of 10

Repeat purchase of this product which I was delighted to find available on Amazon after thinking I would never find it again. If using it in hand wash I wrap the blue cube in Muslin and swish in a bowl of cold water until the water goes dark blue then remove and store for next use in airtight had or box. Then I submitted the item to be given a blue white hue but never leave the item to stand still in the water.lf using in washing machine I crumble a little of cube into a tablespoon of water and add to the conditioner compartment, I don't add fabric conditioner as I use this method for white towels and tea towels which should not have conditioned as it clogs the fibres.

We don't use it for laundry at all. We use it to colour the water for our Church Fete Fishing Game. It is brilliant to see deep blue water with silver wooden fish floating in for the kids to hook out. Have used this since 1967.

It works

In my opinion there is nothing better for net curtains, and these are really hard to find these days. Good old school stuff

I should have bought liquid this is very difficult to get the strength just right and stop blotching and streaking, would not buy again

Old products that still give results

Arrived very quick and well packaged as the dye was coming through the inner package, good value for money

Did not like that this did not come with instructions as to how to use
