Soap scum/lime scale - resists all known treatments

[Stuart Noble]

Sulphamic acid is better for the clueless, or for anyone not wishing to have their lungs and eyes blasted with hydrochloric, or indeed anyone who isn't trying to prove how hunky they are.

Thanks for all the suggestions - even the "Texas Angle-Grinder Massacre" and "Friends of Dr. Crippen" ones.

I'll try the least aggressive recommendations first (bearing in mind that a shower enclosure typically is erected in close proximity to aluminum, grout and glazed ceramics) moving up to diluted battery acid in due course!

But seriously - thank you.

I was rather assuming it would be applied selectively, not sprayed over eveything

Drips!

AIUI not all products described as stainless steel are actually made from stainless steel.

ISTR mention being made of something called "Chromium Iron" amongst others.

There are different mixes for different purposes, and you need to compromise on the set of properties you want. E.g. the most stainless types are useless for sharp blades.

Chrome iron, IIRC, is about 18% chromium; ferritic st. st. (the simplest type) is about 10 - 25% Cr and is the cheapest. It does tarnish - nickel is used to stop that. We used 18% CrFe at work for Rolls Royce wheel trim - then loadsaplating.
