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.
It is slightly wet because of the water I had it soaking in. So it appears slimier than it really is. But the grease won’t come off.
