dimples förekommer i skötselanvisningarna för en badrumsartikel:

Clean the accessories near the WC regularly to avoid stains or rings.

Oxidation and dimples may occur on metals due to the use of cleaning products (even
if diluted) which are declared specific for bathrooms but which are only suitable for
cleaning tiles, sanitary ware, etc.
