I have 2 baking pans that are clean but have a haze on the bottom and sides. these are Rival roaster ovens and I think they are ceramic inserts. Can I get this haze off?
Two opposite things to try, depending on what the haze is (or what works.)
- Barkeepers Friend (mostly oxalic acid) or vinegar (acetic acid, not quite as strong as oxalic.)
- Baking soda and water paste (alkaline) or soak in hot water with baking soda.
- Actually, that brings a third to mind - mechanical - Bon-Ami - feldspar - abrasive but softer than glass (which is what ceramic glaze is, more or less.)
Default assumption would be that it's a hard water deposit, so start with the acid approach, but all three gives you options if that doesn't work.
Another mostly-mechanical option that won't require shopping for a special cleaning product - try scrubbing with toothpaste.
