Am a bit late getting into the Method cleaning frenzy

but have finally made the switch after trying their Tub & Tile and a couple of their liquid soaps
Recently discovered this site selling a Method "Detox" kit:
http://www.biggreensmile.com/products/m ... =mdetoxkit which I've since bought, too much of a bargain not to
(Well, actually, I bought 2 of them

)
Tried their wood polish so far and love the smell and the finish it gives the table & sideboard. Got a few free samples of their washing detergent too. Has anyone tried this on a nappy wash? How does it perform? Only thing I was a bit wary of is that it's a liquid, rather than a powder which I prefer for nappy washes
