I really stupidly left a wet steel can sitting on the wooden countertop last night and I woke up this morning to find that it has left a dark semi circular stain. I scrubbed the stain to see if I could remove any of it, but all I've really done is make things worse. The small area I scrubbed now appears white compared to the rest of the surface because I've clearly removed the finish.
Does anyone have any advice on how to treat this? I've been reading through past posts about using oil, but I want to know whether I would have to sand the whole surface and then oil it, or whether I can just oil this small patch and make it blend back in with the rest of the surface.
Any advice would be gratefully received. I'm really stressing out about it because I'm just renting here, and my flatmate, who owns the place is coming back on Sunday. I feel terrible for having ruined the countertop.
