How to bring up baking trays new again.

[ShyFox]

Is there a way to salvage them or do I need to buy new ones (again!)?

Watching

Watching too

I read a tip and saw some pictures from a cooking group I'm part of - apparently ammonia left on for a couple of days makes them as new again!

Even better for a week if you can live without them for that long. Ammonia can be bought from Robert Dyas.

Get some Pyrex ones. They last forever and go in the dishwasher

tubby do you mean the non stick pyrex ones like these

www.amazon.co.uk/Pyrex-Classic-Stick-Oven-33X25cm/dp/B000W9E54G

Whilst lookin for that I also discovered they do glass ones! But I'm thinking maybe food will take longer to cook and perhaps not be as crispy with glass.

I'm watching too - are we talking about metal ones?
Tip - ammonia is free and readily available in all households. ...

ShyFox, I meant glass ones

I use brillo pads but that's on the stainless steel types.

Jenesuis are you suggesting OP does a wee on her baking trays?

Best baking trays are Silverwood - properly conduct the heat, don't buckle but I'd suggest using with baking/parchment (massive roll from costco lasted me years) and they can't go in dishwasher. If you do have to go the replacement route, worth considering.

I used to try and get metal baking trays like new. Oven cleaner can be useful.

But really, I stopped bothering. I consider the brown stuff to be similar to the seasoning on a cast iron pan. It doesn't affect the flavour of things I bake on them.

I only buy cheap ones and replace when they get too bad!

if you want to give your baking trays a good clean then i would recommend using this oven cleaning set it cuts through grease and grime and will make your baking trays look like new.

I haven't tried it but I want to say scrub with bicarb of soda and wire wool?

are they stainless steel or enamel?
then I would place it on the hob. half fill with water and add a scoop ob bio washing powder.
bring to boil. switch off and scrub once cool. most stuff should come off.
rinse well.
