Right: Clean
Are your aluminum pans discolored?Discoloration that appears on aluminum utensils can be removed by boiling a solution of two to three tablespoons of cream of tartar, lemon juice or vinegar to each quart of water in the utensil for 5 to 10 minutes. Next, lightly scour with a soap-filled scouring pad. Cooking acid foods such as tomatoes or rhubarb will remove the stains naturally without affecting the cooked food product. To remove stains from the aluminum exterior, use a non-abrasive cleanser.
Removing aluminum discoloration on a kitchen appliance requires hard work and is usually only partially successful. I opted for the easy way on a low pressure/convection oven door that was a mess. I suppose this has been done before but I haven’t seen it. I repainted the frame of the oven door, masking parts not to be painted and used Vaseline on spots not accessible. Then using a high heat semi black glossy spray paint (used for grills) I spray painted the door. It may not be aluminum colored but to me it looks as good as the original finish. I also have an aluminum removable crumb tray that was a mess. I opted not to paint that, though. Instead I covered it with foil. When cleaning the oven, I remove the old greasy aluminum and replace it with a new cover. Saves time and work.
Why do cups left on an aluminium draining board leave little black “holes” in the surface? It looks like rust in a steel sheet. Obviously, on aluminium it cannot be rust.
Hi, if you have hard water, the salts dissolved in the water may be pitting the aluminum.
I set a dish with a custard dessert I had made into an aluminum pan half filled with water to bake. When I took it out the aluminum pan is stained with a very dark stain where the water was. It doesn’t seem to be caked on, just stained so how can I remove it. If I can’t remove it, is it safe to use anymore? Thanks for your help.
Here is a blog post that on removing stains from aluminum pans. Try adding the boiling water to the pan with the baking soda, vinegar or cream of tartar in it as instructed in this link. Leave it to sit and do its work. Then scrub with a soap filled scouring pan. Hopefully this will lighten the stain. It has not damaged the pan.
