I dry pail mine- put them in a bucket and then just wash every couple of days. I try to get as much solid off before dry pailing and if the solid is a bit runny then I hold the fleece in the loo and flush to try and get rid of it.
I use a fleece liner as this keeps the poo off the nappy (in theory although it hasn't these last few days cos dd's been ill)
I put a couple of drops of lavender oil and/or tea tree oil in the bucket (tea tree being antiseptic).
I have some washbags (79p from tesco) that I use to carry dirty nappies home in (dd's nappies obviously). If I can get rid of the solids then I flush them but if that's not possible then I just bring them all home and sort it when I get home
