Q: I sealed concrete with Saltguard WB, and afterward, we experienced a large oil spill on the surface. I tried some poultice products with little luck. Since it has already been sealed, it seems locked in. Would your Oil & Grease Stain Remover help? Or would a microbial cleaner be a better solution? 

A: Yes, Oil & Grease Stain Remover would be our only product to test. It should not affect the Saltguard WB at all, but it may take a couple of tries to get all the oil out. 

As always, please follow instructions as stated on the Product Data Sheet.
