Seems I remember boiling in simple H2O will cause a surface layer of aluminum oxide to form - a very durable substance. Only trouble is it's a matte gray finish AFAIK.
Yes in the US I bought some "Air Conditioner Coil Cleaner" liquid which turns out is simply a strong sodium hydroxide (lye) and water solution. It foamed up madly and removed 40 years' worth of dirt from my evaporator and condenser coils on the home HVAC, and shined up my dear departed Granma's espresso (moka) pot. Can't one buy lye drain opener in the UK? Haven't experimented much with it as it requires full protective gear which is HOT and cumbersome in the Tennessee heat... and I actually heed warnings to the point of buying a $90 respirator w/ organic vapor filter for this job. Along with industrial rubber sleeve gloves, face shield, etc.. Having worked on an ambulance here in "Hey man, hold my beer and watch this!" country, I've seen some things...

 Yes you can get Sodium Hydroxide drain cleaner here. some have recommended it for cleaning the drains in the scuttle (probably called something different in USA  ) but I am not sure I want it near paintwork even under the bonnet(hood) as is (obviously) caustic.  By the way, how did the coffee taste?

Aluminium and Caustic soda is a VERY VERY BAD IDEA!

I don't know what the US equivalent of "scuttle" is ("Sump?) however I do know what the word means, but I know VWs and Audis have a definite problem with their (scuttle) drainage! *My wife is from Germany, moved to the US when she was 13; when I met her 20-odd years ago, she could not say the Al word either way; especially funny since she has two Masters' degrees - and one is biology! (A good old science joke here is to have someone say "aluminum" ten times as though it were a tongue-twister, then ask them what a tin can is made of)... Quote:
