Saw an ad on TV recently showing large plastic bags into which you could place oven shelves & a chemical to clean them.
Can't recall any other details & now SWMBO wants some.
Anyone know what they are called?
Useless. At least thats what I called them
We have a box in the cupboard named "Oven Pride" this has a bag and the solution and seems to work!
Why do I keep getting this with tinyurl.com? Everything else is working normally.....

Oven Pride, it's an orange box. Works fantastic.
Ah, thanks. Just found the entry in Zone Alarm. So many things making decisions on my behalf....
There are a few. One is Johnsons Pride (or Oven Pride). A plastic bag with a bottle of under 5% Potassium Hydroxide (or 3-7% Sodium Hydroxide - there are two formulations) and a thickening agent.
Another is HomePride Oven Pride which contains Sodium Hydroxide (less than 12%) , Alkyl Imidazoline Betaine and EDTA Na4 (latter both about 1%).
You can make your own using a solution of Sodium Hydroxide (Caustic Soda) or 880 Ammonia if you are adventurous. Paint caustic liquid over shelf, stick in bag and leave a few hours. If using 880 Ammonia put a tablespoon full on a rag and place rag and shelf in bag for 24 hours. The fumes from 880 Ammonia are _very_ strong so do this outside.
It's probably Sodium Hydroxide (Caustic Soda), possibly with addition of some surfacants (detergents), perfumes, colours, thickeners, profit margins, etc.
Get a plastic storage bin big enough to lay the shelves flat, and cover with 10% caustic soda in hot water (add the caustic to the water gradually of course). Leave overnight. Use a nylon washing up brush if necessary. Always worked for me.
The other alkali options mentioned aren't really that practical. Potassium hydroxide isn't easy to get hold of and doesn't do anything the sodium doesn't. Ammonia, even the household strength, is just impossible to work with although I suppose, if the bin lid was airtight, it might be an option. Can't see the benefit over caustic soda though.
If you're tight like me you just stick them in a taped-up black bin bag in the garden overnight with a slug of household ammonia from the pound shop. The ammonia fumes do something-or-other, and by the next morning the gunk wipes off with a sponge. The =A31 bottle will last you years.
Hmm, does used cat litter work too? ;)
Convert the fatty acids to water soluble soaps
and by the next
I suppose that could work in the cooker itself if you could locate all the gaps to seal. Unlike the caustic soda based cleaners, you wouldn't have to worry about chemical residues being left in the oven.
The ammonia is rather corrosive to some materials, and might damage other bits of the oven, particularly with repeated use.
It's more about what it doesn't do that the sodium hydroxide would. Potassium hydroxide can be used for cleaning metals like aluminium (rinse well afterwards though!) where sodium hydroxide would attack the metal immediately. Many of the mountain bike cleaner sprays are based on potassium hydroxide - not great with eyeletted Mavic rims though.
So you prefer Vegemite to Marmite then?
I imagine all cookers are built to withstand oven cleaners these days, inside and out. Would ammonia be any different to the other strong alkalis?
It works very well and (even with 880 Ammonia) you don't need to seal the gaps, just put a cup about half full with it in the oven and leave
24 hours. After the rather exciting performance of decanting it and putting it in the oven no noticeable fumes escape.
You obviously don't clean the oven or grille shelves. They're brilliant.
I use caustic soda in a bath. 1.75 for a carton that lasts 2 years
