Someone had asked why I don't clean my salon sink.  Surprised, I went to check on my sink.  Yes, I could see the stains that they were talking about.  But no matter how much I cleaned, the stains did not go away.  The shampoo sink in the salon station is a Belvedere made back in the 1950s.  It was used in a salon ever since, so it's been stained from bleachings, perm solutions, and who knows what else chemicals the sink has been splashed with.  (Hair products back then were not as gentle as they are now).

I hate to replace the sink just yet, even though the faucet mounts are starting to crumble in the back.  I will repaint the sink with white enamel paint today.  Hopefully the sink will last just a few more years, then I'll replace the entire thing.
