Where do you get that from? From the P&G web site;

Viakal can safely be used on:

Chrome fixtures, stainless steel and fibreglass surfaces, ceramic tiles,
porcelain (sink, shower tray, WC, bidet), glass/plastic (shower doors,
plastic baths, vases), aluminium. Viakal is also safe for septic tanks.

Maybe it's not as strong as it was 8 years ago, when it stained
my stainless steel sink.

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

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.
