There is a waste ground behind my back fence. An eco-friendly way of getting rid of slugs from my garden is to collect them by hand and lob them over the fence (though I'm sure they make their way back). However, I am left with a lot of slime on my hands after a session of slug lobbing which soap, bleach, lemon or vinegar can't shift. Only a pan scourer liberally applied will get the stuff off. Any less aggressive ways to clean off my hands please?
