The basket occasionally went in the dishwasher which cleaned the surface, but the well gunked grease has been building up.
Tried soaking the basket in soap and hot water. Scrubbing with a soft sponge. And then running the dishwasher multiple times but it only got a small part of the grease out.
Not silly, that’s a common cleaning technique from janitor/cleaning staff i was told a while back. Use a little bit of what causes the stain/gunk and it helps break down the bonds by binding with the already-solidified object and trying to mix with it, weakening/changing the concentration of the ‘stuck’ substance
