I am sure I have read on here about someone using this stuff before. Tesco had two boxes in the chuckout today so I bought them both !

Not sure how much to add to a washing up bowl of water? Any ideas?

One box makes a bath full so id use about half a box. I didnt think wed have enough to fill a bath with one box but it was plenty. The powder you put in to melt it is good too so it easily pours down the sink. :)
