I've baught some play sand today. 15kg for £2.99! Bargain. Anyway I know it contains some dirt so will need cleaning well before I put it in. I was thinking of using an old flour sifter I have spare and putting the sand in there and running it under a tap. I know this will take aaages but I don't have a bucket spare and we've had none stop rain for the last week with more forcast in the next few days. Any other way I can do it in the bath?
