This is an Aga. Years of fat and oil has been oxidised all over the
enamel and chrome parts on the top to make a solid coating. In cooler
places it's soft, very hard where it has been hotter and burned right
off only on the very hot places like the hot plates themselves. How do I
clean it off?

So far tried various 'dissolves grease' cleaning products and green
scourers. Doesn't really work. A blunt table knife seems to remove the
stuff without scratching the enamel too badly but it's very laborious.
Is there a chemical solution? Even to soften it up?

we have carbon steel frying pans (pub kitchen) and when the underneath gets
caked in burnt on fat thats the only thing that will remove it with a

Scrap it off and then use wet and dry and buff with T-cut.

Or get teh whole top re-enamelled

Sodium hydroxide.

You used to be able to buy it in a "jellied" form which you plastered on and left for a couple of hours and then washed off.

I don't think even the old Methylene Chloride "Nitromors" will touch the
worst of it. Boiling, strong sodium hydroxide solution probably gives
you the best chance. Not recommended unless you are used to handling
aggressive chemicals.

The lacquers from oxidised oils and greases are *very* chemically
resistant. Otherwise you are down to mechanical methods (wire brush,
sanding disk).

When were were students, a place we rented had a Baby Belling cooker. It
was pretty grim when we moved in- various oven cleaners didn't really do
the job.

I mixed up some strong NaOH sol., immersed the bits I could, and used a
paint brush to apply the rest- covering it with kitchen roll and cling film.

After maybe and hour, I cleaned it all off and there wasn't a trace of
old grease etc.

Thats rather different to the top of an Aga tho. Certainly worth
trying, but it wouldnt be surprising if its much harder to fix.

But surely it must be well known how to fix an Aga by now ?

But only on reasonably flat surfaces. Great on ceramic hobs, but Aga
hotplates are machined cast iron and the enamelled parts are not
particularly flat.

I've just been cleaning off kitchen grease today. Tried for the first time what I call public toilet cleaner on it - and it's pretty good. It's what's used industrially for toilets, available from janitorial supplies. Does not smell good.

If you're going to scrape it you need to use plastic, else the enamel will get trashed.

If using caustic I'd brush it onto the heated surface. DO wear eye protection.

Steam cleaners are good for some kitchen grease, certainly not all but it's probably an easy way to make some progress.

Whatever you use may need many soakings. Patience is better than wrecking the finish.

top after every use or so for cooking so the fat doesnt

That's okay with gas cookers, not so wise for electric ones in case the water gets in the electrics, and definately not recommended for Agas as they're filled with insulation which would get waterlogged.

Probably.

If you don't have a live-in kitchenmaid or tweeny who can do it at 5 am every morning, the daily woman 'for the rough' may be entrusted with this work under supervision.

Those, on the other hand, for whom domestic arrangements have moved on since 1939, and who would like to reduce their energy consumption to approx 1/32 of an Aga, will have bought a cooker that can be turned on and off, and wiped clean with a damp cloth.

A local 'boutique' charity shop has one as a display piece.

cooker outside and powerwashed it.

That's okay with gas cookers, not so wise for electric ones in case the
water gets in the electrics, and definately not recommended for Agas as
they're filled with insulation which would get waterlogged.

Bearing im mind the weight of an AGA, I can't imagine anyone "taking it
outside to wash".

Many years ago, I heard this terrible loud hissing and gurgling from a few

outside and powerwashed it.

Every part of an electric oven can be wet washed as long as it's thoroughly dried before reconnection, except motor bearings.

This is an Aga. Years of fat and oil has been oxidised all over the
enamel and chrome parts on the top to make a solid coating. In cooler
places it's soft, very hard where it has been hotter and burned right
off only on the very hot places like the hot plates themselves. How do I
clean it off?

So far tried various 'dissolves grease' cleaning products and green
scourers. Doesn't really work. A blunt table knife seems to remove the
stuff without scratching the enamel too badly but it's very laborious.
Is there a chemical solution? Even to soften it up?

What about a steam cleaner?

ROFLMAO. You have never owned an Aga have you?

No :-(

Even sidium hydrxide does not work on this.

I have had an aga for 14 years....

Are you saying that that is a very fundamental design flaw
and that the only viable approach is to clean the enamel
top after every use or so for cooking so the fat doesnt
bet baked on ?


Yes.

Have you tried conc nitric acid ?Â* That should get it off, but isn't
that easy to get.

what does that do9 to carbon?


It removes the iron!

No, it doesn't. Even fuming nitric doesn't.

There are limits to what I'll use as a cleaning chemical. Boiling strong fuming acids are a good 2 steps beyond that point.
