The granite particles bonded together during manufacture are now smaller, creating a smoother, flatter surface, reducing the chances for limescale to build up. It is also far more difficult for residue, food particles and bacteria to accumulate in between the granules, which greatly improves hygiene.
Fragranite

Following extensive testing and development, new Fragranite tackles the humble cleaning problem associated with composite sinks.
The revolutionary new Fragranite+ technology is now available on all Franke Fragranite and SilkSheen Fragranite sinks, which now enjoy ultra-smooth surfaces that are exceptionally easy to keep clean.


Tested against leading competitors, DuraKleenĀ® Plus comes up trumps on stain resistance. Even after being left to sit on the sink for 18 hours, the toughest stains like beetroot, permanent marker, red wine and Iodine can simply be wiped clean away.

This chart has been developed by Franke to assist in grading the various materials in terms of their performance characteristics for each category.
It is intended to act as a guide for different requirements: 10 points - the best material tested in this performance category. For example, in our tests Fragranite/SilkSheen scores highly in scratch resistance and hygiene.
