Shine on sink

A mission for today is polishing the sink of kitchen. Of course, it has not been cleaned for a long time. So that even stainless steel stains. Sad. And the gap is covered by alminium tape, and it looks to come off easily and look ugly. Sad.
My tool box is always ready for this kind of situation. I have got, strong scraper, sharp csraper, stain remover, metal polisher and discgrinder. In a few hours, the sink get back the shine.
