Hello everyone. Looking for some help with my wooden worktops. We had a new kitchen with oak worktops installed in February. The worktop was oiled with 3 coats and looked amazing. Enter my girlfriend and some bleach... The resultant inch long black mark was right dead centre so needed to go! I tried buffing it out but that didn't work so I used some sand paper to get it out. I went with the grain and it came out really quite easily. The issue now is that I have oiled the sanded part with the same oil as used originally however you can still see the circle or where I sanded. Is there something I can do to blend it in or will I need to sand the entire worktop?
