Dylon Washing Machine Fabric Dye Pod Intense Black, 350g £5.95 / £5.05 (S&s)

I found after use in a washing machine I’ve spent what seems like hours having to clean the rubber door seal. Even now when I remove sheets from washing some how they seem to pick up some black marks from the seal. I would only recommend using this is an old washing machine, else use a sink bowl.

PS. they were £3.95 in home bargains, not sure if that’s still the case though.

I don't want to share details but don't do it if your machine uses a small bucket of water, it won't even dilute. It will leave black slur-like grease inside which will stain cloths like a black mould (machines mould inside that silicon collar anyway so it will stain extra).

I didn't do that, but I had to empty one of those machines and that took about 5 hours, an enormous amount of bleach, citric acid, and soda (whatever I found corrosive, some worked partly on one kind of "dirt" then another substance removed some "other"). I left the machine full of water overnight as well. After that, I increased the amount of taken water by the pressure switch as well as the "eco" mode was a waste of time.
