Restoring an old bathroom sink

What's it made of?

I believe it's plastic

Some of the plastic sinks are really thin, so you need to be careful, but something to gently 'cut' the top layer might work - toothpaste is a safe bet, it certainly works on yellowed plastic car headlamps although a fair bit of elbow grease is required; try it on a small discrete area first would be my advice.

T-Cut for polishing car paintwork or Autosol should work. Both are very mild abrasives, as is toothpaste above.

 Thanks.

Would these act as a cleaner to restore or would it still need painting?

If so, what type of paint would be best?

Thanks

The cleaners mentioned, Tonker, should leave the surface pretty much the same colour as new always allowing for some degree of fade ~~  you really wont get it right back to " As New " condition no matter how long you spend on your knees   .  After the item has been gently fettled up then just a simple swill over with warm soapy water should remove any gunge left, then bingo -- get yer washing up sorted, Laddie  !!

Thanks everyone, I shall get onto it. I feel like I know you well ABM!!

Made for marine GRP applications Y10 is non-abrasive and very effective at removing staining in plastics. If cutting paste isn’t effective it might just do the job
