off my carpets? off my kids doors?

I am just so unsure how to get it off...

I was in bed early as i feel really sick and tired, and DF was watching the kids.... (or so i thought lol )

Anyhow, he has come in furious telling me the kids have used one of DS's old nappies (where they got it from i have no idea), and spread the crystals all over the floor, door's, walls... he said he has tried vacuuming and it is not doing anything. I honestly dont know what to use????

what do you think???

so embarrassing lol dont ya love kids!!!! lol
