Because the kitchen company who installed it didn't tell us

There must be a lot of builders and masons hoarding the Caesarstone cleaning kit then, as you automatically get it when you register your product online through the Caesarstone Warranty Registration on their website.

I understand Selleys has taken over this product from Hillmark.
There is an MSDS for this products at http://www.hillmark.com.au/Products.aspx
Click on the Stone Clean & Protect image, then you will find an MSDS.
My wife just uses Aldi's window cleaner and our benches come up a treat.
Any residue of chemicals usually evaporates and just to be certain before rolling dough etc, she pours some warm water on the bench and wipes it away.
Cheers

Thanks Bob! But my understanding is that not all these types of chemicals are completely volatile, and neither are the colourants and carriers. I think wiping down before use is good anyway, but was more concerned about the benches absorbing some of these chemicals and then releasing it into an oil carrier, ie. the butter in the dough etc...
The benches aren't 100% impervious, so I was wondering from a chemistry point of view. Thanks for the link to the MSDS :-)

I would not use this product on my bench tops ever again. If you read Glenda's review here above, she is completely correct in what she says.
I cleaned my 6 month old white Silestone benches with the Hillmark Stone Clean and the product left it blotchy, dull and streaky. It sucked into the bench and I am truly hoping that I can restore my surfaces back to how they were and hope to god that this product has not caused any permanent damage to my Silestone surfaces! Not Happy at all!!

I have given up on finding the Selleys Stonebench Clean - however, I have found something I believe is much better - Polyglaze Waterless Car Wash - purchased from Super Cheap !! It is truly amazing and cheaper. My granite bench top has never looked so good. Give it a try and let me know how you find it. Cheers, Denise.

Thanks Denise..
