Kitchens are breeding grounds for germs and bacteria as it’s the place where food is handled almost daily. Therefore, the good health of you and your family depends on the hygiene standards in your kitchen area. Materials that are used for daily activity that come with unprotected surfaces suffer from the rapid growth of germs, making these surfaces unclean and unsafe. The integrated Sanitized® hygiene function helps to keep this area clean while also protecting for longer periods. Although not meant to substitute normal cleaning, it helps to keep bacteria at bay.
Sinks are one such surface that faces the daily onslaught of bacteria. After extensive research and testing, the new Fragranite tackles the cleaning problems generally associated with composite sinks in more ways than one.
Germs: Once treated with Sanitized® the surface experiences reduced bacteria and germ growth by 99% while also offering lasting protection against microbes.
Scratch: It makes the surface scratch resistant so that you no longer have to worry about bruises and scratches from kitchen instruments.
Impact: Offers resistance to impact and thermal shock.
Stain: The original colour remains stain-free and is also easy to clean and maintain due to additional SilkSheen technology.
Colour: Prevents surface colour from fading and becoming dull and stays good as new for life.
Heat: Heat can cause severe damage and affect the lifespan of kitchen appliances and surfaces treated with Sanitized® will not be affected by heat up to 280°C. 
Fashion: Best part is its availability in multiple styles and colours to suit every need and kitchen.
Please Note: Fragranite colour shown in the image may slightly differ from the actual product.

Does the Job!
Very good quality finish and strong. Came with waste fittings which was a pleasant surprise. Does stain quite easily but cleans up perfectly back to pure white. Would buy again!

Good Value
The price was the lowest I could find anywhere. Delivery was fast and efficient. I was very happy with the QS Supplies Service, and the Franke sink that I bought.

What is the best way to clean my sink, its only three months old and has a few stains on it, can I use Cif Cream cleaner on it with a sponge that has a nylon scouring pad. Thank you

I have been told that if you dissolve a dishwasher tablet in hot water and leave it for a few hours, this works. I tried it once and it worked but it was not badly stained.

I use the Cif powder with a nylon scourer, don't be afraid to give it a good scrub. I sometimes use a bit of bleach and let soak just for a few seconds and then scrub and rinse for really stubborn stains.

Answered By Lawrence :
I phoned Franke up directly and they basically said the only way to clean it properly is with a scrubbing brush and cream cleaner. Bleach also works. We were very disappointed with the sink we had no idea it would be such an ordeal keeping it clean ! We had expected it to be an easy clean type of ceramic sink which it definitely is not as it has rough surface not smooth ceramic. You really can't tell by the photograph. Sorry to hear you are having the same experience as us. Keep scrubbing :).

I have used cif cream cleaner and flash with bleach which worked better. Diluted bleach was best and still is after 2 years of use.

Napisan! I only discovered this since having a baby but if you fill the sink with hot water and add some napisan, leave it overnight and your sink will be sparkly white again

I have this sink and when stained we pour a little neat bleach into it and work around with washing-up brush and rinse immediately. Works fine with no issues so far (1 year old)
