Hi Alan when i work with stainless to guarantee absolute cleanliness I wash with acetone the easy way to obtain this is in basic nail varnish remover (avoid the ones with conditioner etc) you can also buy it from a chemist . Word of warning though it is very flam able and vaporises very quickly this is also a very good degreaser for non ferrous and ferrous metals. cheers Steve C --------------------------------- How much free photo storage do you get?
