ive got a brill little metal grinder, only thing is, where the lid sits & you twist to grind bits of green have got on the outside making it difficult & 'sticky' when grinding, ive tried scraping but that just marks the metal. any ideas peeps? cheers
Soak it in methylated spirits and it'll come right off. Just make sure to give it a real good rinse with water after.
Put your grinder in the freezer for an hour then you can knock all that extra keif out of the little spots in your grinder and into the bottom
