I have a blue Pyrex baking dish and I can’t get baked-on cooking spray off of it. Last week, I sprayed it with “vegetable oil style” cooking spray, which smells just like the linseed oil used in oil paints. I only needed to use half the pan to bake my banana bread, but I sprayed the whole thing. Now, the half that didn’t have banana bread in it has baked-on oil and I can’t get it off. I tried scrubbing it, soaking it (for over a week now) in bleach, hot water, dish soap… It won’t come off. Does anyone know how I can clean my pan? I guess I could try paint thinner or turpentine, but that might ruin it.

Dawn makes a product that has a name like “Power Dissolver” that works pretty well for this kind of thing. It comes in a small, dark blue trigger-spray bottle. You spray it on, let it sit for a while, and, while you may still have to scrub, it does help loosen it quite a bit.

An old-fashioned Brillo pad will probably take it right off. I believe Pyrex is harder than the fine steel wool, so you’re unlikely to scratch the pan unless you scrub excessively hard.
Something else that would probably work well is one of those newish “magic eraser” cleaning pads.

I second the Dawn Power Dissolver. Works as advertised.

Nope, it won’t ruin it. I use much harsher solvents on pyrex labware all the time. I would try straight acetone or rubbing alcohol first though, as these will evaporate and leave no harmful residues. If you do use paint thinner or turpentine, be sure to wash it very well after.

Thank you all, and especially \masterofnone\. The rubbing alcohol took it right off!

Try a paste of water and washing soda (get it in the laundry aisle). The main thing is to let it sit for a while to dissolve the crud.
Washing soda is great on greasy, oily stuff.
