Kitchen Sink Strainer De-gunking

Skimming the strainer

Skimming the strainer

We have a (formerly) white plastic strainer in the kitchen sink that has acquired a brown biofilm layer. Bleach is moderately effective, but the surface is just ooky.

Green tea is suspected, but the evidence is not, at least according to me, conclusive. More research is in order.

Took the evidence to the Basement Laboratory’s Machine Shop WIng and skim-cut both faces, cleaned up the rim, drilled out the holes, countersunk the holes to get rid of the chaff, and it’s all good. The surface is probably too rough, but we’ll see what happens.

I figure I can do that maybe twice more before I must make a new one; looks like a perfect match for CNC, doesn’t it?

    I would like to know where to get these. I love them and they are the most affective strainers because they fit inside the strainer. I used to buy them at Walmart but I can’t find them now.

      Although it’s not much help, I eventually did make replacement strainers on my CNC milling machine:
      CNC Sink Strainer
      … and 3D printer:
      3D printed sink strainer
      The CNC strainer is clearly the better of the two: the surface is smooth, flat polycarbonate that survives trips though the dishwasher and comes out clean.
      It’s also dark gray, so crud doesn’t stand out; I have no idea why they thought a white strainer made any sense at all…
