Why did my rum cake turn black?

This is an interesting question. Personally I would throw it out, the discoloration and resulting taste are the result of a chemical reaction with the pan. The brownish discoloration is a sign that ...

How do I know what kind of coating is on this pan?

Whitford is, in fact, a chemical company that makes nonstick coatings, so the label makes sense. Since 2016 they've been offering PTFE (Teflon) without PFOA, so that's most likely what the coating on ...

Seasoning old non-stick aluminum pan?

I tried seasoning an aluminium kawali and was pretty successful doing this. I cleaned it very well and then layered it with a bit of oil (use peanut or canola) and then baked it outside on the bbq (or ...

What is this rust-like stain on my aluminum pot, and how do I clean it?

This will be from an electrochemical reaction between the can (mostly iron I think) and the water and possibly the aluminum (a better chemist than me would be able to tell you). Aluminum has a ...

I think this means that the Whitford company has a "house recipe" for a pan coating that is not teflon-based ("Sans PFOA" means without a helper chemical that was used in teflon ...

How to clean aluminum with lye "stains"

A weak acid solution should do it - you could use a dilute (white) vinegar solution for some time. How dilute, I don't know, but I would start with a 1:100 dilution, then incubate for an hour and see ...

Need help cleaning an old aluminum coffee pot

You can buy kitchen-safe aluminium cleaner & descaler - the white could easily be limescale. If you look at 'home-style' cleaning guides, then everybody seems to have a different opinion - some ...

It is oxidised aluminium (Al2O3). This is formed by oxidising with the oxygen in the air to form the aluminium oxide. Al2O3 forms a very thin (4 nm) impermeable layer on your Al, which prevents ...

How to clean stains from anodized aluminum pans?

This looks like you are starting to getting a layer of polymerized oil on the pan, like the seasoning on a cast iron pan. I wouldn't try removing it. The usual methods are either using a strong base ...

Durable loaf pans for quick breads?

You asked for 'durable'. What's wrong with 'proper' traditional pressed steel? Sure they take a while to season in properly, but after that, they last a lifetime… or two… or three. I'm still using ...

What material wok did I get while thrifting today?

Mine was purchased a few days ago at HKD128 (discounted) at IKEA. It's definitely not aluminum as magnets are attracted to it very strongly. It feels like steel but not sure if it's carbon steel. It ...

What material wok did I get while thrifting today?

IKEA cast iron skillet that sells for about $179. Going to look different because it’s not as heavy as a cast-iron frying pan. But it is indeed a cast-iron pot and you have to treat it the same way as ...

What determines if the handle of a pan gets hot while in use?

The other consideration that I've see is ... how big a gas burner do you run it on? If the flames come up the side of the pan then they heat the handle from hot gas and not from conduction from the ...

Can't make an omelette in my all-clad pan because of sticking

It also happens to me sometimes, what I suggest you do is spread oil uniformly on the pan and make sure you pour the egg in the middle of the pan. If the pan has oil on all sides it does not matter if ...

Used Metal Knife on Aluminum Cake Pan, is it Ruined?

Steel (as used in knives) will always scratch aluminium, which is really quite a soft metal. Glass and even some plastics can mark it quite noticeably as can storing aluminium pans stacked together. ...

Can I use a metal spoon on aluminium pans?

On an aluminium pan, no, it's fine. It's only teflon, AFAIK, that is dangerous. However, sticking to something like wooden spatulas will be better for your pan and make it last longer.

Remove burned-in oil from aluminum pan

The ultimate way to remove burnt-on stuff from aluminium is a motorised wire brush. Solid brass is fairly aggressive but manageable (watch out for brass-plated steel, which is too hard). Sets are ...

Never use steel wool on an aluminum pans or put in the dishwasher. It damages the surface and as others have said, provides fresh O2 to form oxides. Use scrubby sponges or brushes after soaking if ...
