How do I clean this? *Pic included*

[Tempusfudgeit]

Help, me, Oh wise people of Mumsnet!

How do I clean this oven dish? I've tried soaking it in hot soapy water and scrubbing, but no joy.

Any ideas welcome, even mad ones if they work! I have arthritis in my wrists so the least elbow grease option the better.

I await your wisdom.

I don't clean pans like that, other than hot soapy water to clean. All my roasting tins look like yours.

Is it stoneware? If it is it is meant to look like that. Hot soapy water once it is cool after using.

Pink stuff or fairy cleaner and wire wool

You could try sticking a dishwasher tablet in it with boiling water and leaving it to soak that may help a bit .

Pyrex? Mine look like that too. I'm contemplating oven cleaner...

Get one of those oven cleaning kits where you soak the racks. Stick that in the bag instead.

Boiling water straight from the kettle and then scrubbing? Take care not to burn yourself obviously.
Soaking in some biological washing powder (not with boiling water though or the enzymes get denatured)?

Why do you want to clean it? To make it look new again? I would just use soap Atwater to ensure that general grime wasn't going to fall off in to my next meal, and then not worry about it.

Is it glass or some other material?
Astonish oven and cookware cleaning paste is good

A good scoop of vanish laundry powder dissolved in hot water. Leave soaking for a few hours.

Put it in the sink. Plug in. Crumble a couple of dishwasher tablets over it, put a few glugs of white vinegar and cover with very hot water (boiling is best) then leave it until the water is cold. Empty water. Fill up again with hand hot and washing up liquid and use a Brillo scourer to clean.

Brillo pad and elbow grease!

Bicarb and white vinegar. Leave to soak. For ages.

Oven cleaner, but wash it really well afterwords.

Try biological washing powder. That brings most shit off pans etc. Fill bowl with water submerge rusting dish, add scoop of powder, leave to soak. May need a couple of goes.

Alternatively soaking in soda crystals might work. Am assuming here that it's a Pyrex glass dish. Don't put soda crystals near anything aluminium.

2 dishwasher tablets, fill with water and leave overnight.

I was going to suggest soaking it overnight using Sterident denture tablets and water.
I'd make sure that the sink has the plug in, fill with enough water that will mean when the dish is in the water it is submerged and then add the denture tablets.

Buy a new one!

All my metal roasting pans look like that. I've never bothered trying to make them look like new. It's just staining. It won't affect food cooked in it.

Wire wool and lots of fairy liquid in hot water (assuming it's stoneware).

I use this also. Sparkling like new!

Cif is amazing. Scrub the pan with hot water and wire wool/scrubber, and leave the Cif to sink in for a hour or so then soak the pan in hot water.

Pretty sure this ISN'T metal?

So, while all mymetal roastign tins look like this, if it isn't metal, then I can see why you would want to clean it.
