Unfortunately i have not been out in the woods for a while back then a trangia was abused with a brillo pad, the ones with the soap impregnated in them! Since then i have been slowly gathering some quality bits of kit such as my stainless zebra billy and also a optimus cook set. I have a trip due in the not to distant future and am looking forward to field testing my gear but I wondered what other did to clean their cook sets in the field?
