How to clean plastic knive handles?


I have these knives that I bought 15 years ago at Costco that I absolutely LOVE. Unfortunately the handles are very dirty. Looking for solutions. They are rough so scrubbing with a green scrubbie is. It good. I’ve tried BarKeepers, Baking Soda, magic eraser, bleach. Maybe some combination of products is needed?? I’ve wrapped them and let them soak before but would like whiter.

    Have you tried making a thick paste of baking soda and hot water, smearing this over the handles, and let set, overnight? Next day, apply a few drops of hot water and scrub gently with a microfiber cloth. You may need to repeat this, but it's quite effective at removing heavy duty grime.

    Hi Gwyn. Try wiping them down with straight rubbing alcohol. Lay the knives down on a flat surface and wipe one side and then the other. Good luck Gwyn.

    Hello. I’m surprised the barkeepers did not work! I would’ve thought that would’ve been your solution.

    Do you feel like you have hard water there? Sometimes a little CLR can remove lime residue which might be holding onto the stains. Just a thought—- that happens in my sink stoppers areas. Hope you find the perfect solution to restore your knife handles. Good luck.

    I didn't see alcohol listed. Try that. You could also paint them.

    Try a Mr Clean magic eraser, they work wonders!

    Amagic Eraser is like using sandpaper on the knife handles. It will take off a very thin layer. Since you have tried everything I would get some 1000 grit wet sandpaper and use with baking soda to see if you can get them white again.

    I wouldn't try painting them, because they will flake.
