Q. There are strange spots from cooking oils on a family member's Absolute Black kitchen deck. White "ghosting" type of haziness. It had been sealed but I don't know the product. Spoke with all my fabricators, none have heard of this type of thing. We'd like to know the best way to rid this. (My company did not have this stone installed). I would like to give the homeowner a phone # and/or info.
A. If a sealer was applied to a granite that did not need to be sealed in the first place or it was not properly applied and the excess was simply left to dry on the stone when is should have been thoroughly buffed off it could present the problems you are describing. In other words, the sealer itself is 'etching.'
Have them try using acetone on a clean white rag to see if the 'ghosting' goes away. If that doesn't do it, they could step it up a notch and do the same thing with MEK. Of course, make sure to tell them to use all appropriate precations when using chemicals.
If that still doesn't resolve the problem the it is not the sealer that is causing the problem.
Another possibility is they have a doctored slab. You may want to visit www.doctoredstone.org for more info on this.
