Subject: leather grill gloves
Not really a cooking question. Over the years, grease has gotten on them. I've owned them for over 20 years. Problem is, the grease (or any liquid) gets into the material (cloth, leather, etc), and when you pick up something hot the grease heats up, transferring the heat to my hand.

I've been doing some searching, but I can't seem to find anything about how to remove the grease and clean the gloves. Everything is about smooth leather work gloves (or similar). Not suede-like grill gloves. They are similar to welder's gloves, but I don't think anyone anticipated grease migration into welder's gloves.

I tried soaking them in Dawn, and it did improve them. But I may have reach a plateau of how much grease that will remove. I may try a suggestion I found about using a baking soda paste, applying it, and letting it sit overnight. But from what chemistry I know (not a lot), I don't see how baking soda will cut the grease.

Any ideas??
