Just had this installed less than a month ago. Long story short, I’m pretty sure these are oil stains coming from my hood vent. At the bottom, I suspect there was grease on the countertop before install and the stone just soaked it up. Reached out to contractor and he told me to order Akemi Oil and grease remover, get the stain out and they will come back out and reseal, and even silicone the edge. I guess my question for this board is what are the chances this remover will actually work since I think the oil is being soaked up on the cut edge, where I obviously can’t get to? And is there any other recommendation? Obviously I have some issue with grease getting trapped…maybe there is some filter I’m supposed to be cleaning.
