Removing Sulphuric acid stain on granite 

.

I have spilt 'Black-it Patina Solution' (used for blackening solder) on a 'emerald pearl' polished granite kitchen worktop - and it has caused a white stain on the granite due, I am advised, to the sulphuric acid in the solution. Can anyone please advise me how to remove the stain and restore my kitchen in time for Christmas. I would be very grateful.

The Acid has reacted with the Granite and etched the surface very slightly. It is quite possible that the damage is minor but the most reasonable method of restoring the surface is by polishing.

Two paths could be taken, first check Granite and Marble suppliers to see if they offer supplies or a service to polish. Second, go to an automotive store and buy rubbing compound and an electric polishing machine (this machine will reduce a few hours of work to several minutes). Then following the instructions with the compound re-polish the counter top. The Granite is quite hard and you have little chance of damaging it further by repolishing.

Thanks, Jaye. I'd agree that the rubbing compound brings little risk -- except that removing some stone while still leaving a flat surface isn't dead easy as anyone who has sanded a floor has discovered :-)

My name is Shirley and I have a problem. I used the Wallflowers plug-in fragrance in my bathroom and accidentally unplugged it and set it on my granite countertop. Now I have a BIG stain. How do I remove this type of stain. The perfumed fragrance feels oily and I am not sure what is in it. Please Help????
