Help...burnt pressure cooker...cleaning tips please

[grouchyoscar]

Hello all
Tuesday I managed to let my pressure cooker boil dry. I almost welded it shut but when I prised it open I was confronted by cremated butter bean and barley soup.
I discarded the loose stuff but some of the burnt offerrings have adhered to the pan. 3 runs through the dishwasher and attacking with a scrubby sponge have done a bit but not a lot of good.
ATM the pressure cooker is soaking in warm water with a washing tab in it but do any of you wonderful people know a surefire way of getting the insides silver rather than black please
Thanks in advance

Fairy power spray ?

I saw this on How Clean is your House, but I haven't had chance to try it out yet...

Pour some full fat Coke into your pan, and bring it gentle to the boil. Keep it boiling for a few minutes, swilling it round as it does so. IIRC, the burnt stuff just comes away.

Thanks VWVic

The pan is on the stove with 2l of coke in it and it's working!!!!!! I can feel the burnt stuff lifting.

Will update in anj hour

IT RUDDY WORKED!!!
