wow this sounds interesting... will give this a go and let you know how I get on! Failing that I'll try the other suggestions. Thanks everyone. xThe best way to clean roller wax heads is to soak them in vegetable oil. I put my used ones in a lidded pot, leave them to soak over night and they come out like new! Just rinse them off, sterilise and you are ready to go. Try it, it really works.
