PICK YOUR PREDICAMENT

What’s that mark?

A starting-point finder, not a diagnosis. Describe the mark, then check your toilet’s care instructions before choosing any cleaner.

THE FIRST MOVE

Check before you scrub.

The same colour can mean different things. This tool suggests a reading route, not a product or chemical recipe.

For a ring, read the limescale guide. For removable residue, read the cleaning-order guide. Check unknown finishes with the maker first; damage, leaks and drainage concerns need appropriate advice rather than a stronger cleaner.
