The other day a painter came to paint a wall white and he washed his tools and buckets in my black kitchen sink that's made out of silgranit. I don't know the composition of the material but it's got a rough surface, if not porous, and it looks like small white flecks of paint got embedded in it.

How can I get the wall paint out of the sink's surface?

    #1: pick up the phone, #2: dial your painter, #3 "hey bozo, get your dumb @$$ back over here and fix this mess". The alternative may involve something like a "brush cleaner" which will soften the dried paint, but might not be friendly to your plumbing in large volumes or high concentrations.

  • Before i tried any harsh chemicals or abrasives that might scratch, id try scrubbing it with something like a 3M brillow pad (the green ones not the meatal or sandpaper ones).

    I was thinking a porous surface would be very bad for a kitchen sink! So I went to the website, sure enough, it states that it is non-porous. You may want to check the Blanco website for cleaning advice.

    Step #3 in @brhans' answer might include the painter paying to have a plumber replace the whole sink if he can't get it clean or further damages it in his attempts to do so. Photographic evidence before he returns would be wise.

Base is acrylic, so you should not use chemicals for paint removing, like lacquer thinner. Some strong cleaning staff, like sodium hydroxide.

  • @blacksmith37 The post has a link. Technical info said acrylic. Polyester soft, melamine is used for similar.
