Previous owners used some sort of sparkly countertop finish cleaner that stained everything a yellow color.

Like the title says, we just moved into a new house and the countertops look like the previous owner used some cleaning supplies, or maybe re-coated the top, and now there’s as yellow stain everywhere. It’s hard to tell in the photos but the issue is pretty bad. If you look as the difference between the framed pictures in the third picture and the countertop you get a better idea of how bad it is. I know buying new countertops is an obvious solution but it is not feasible for us right not. Any ideas on how to clean these?
