Bio-D bathroom cleaner (100ml)

Bio-D's convenient, versatile ready to use Bathroom Cleaner is ultra-effective and tough on limescale and watermarks. It can be used on glass, ceramics, perspex, chrome and most non-porous surfaces: just squirt, wait (not too long) and wipe.
 
(Note that it is not recommended for use on gold plated items.)
 
Used regularly, it will stop the build-up of limescale too.
