Final Cleaning of PLA

Recommended Posts

Posted · Final Cleaning of PLA

Here's a handy hint I've been meaning to post for ages; if you have a PLA print that's been discolored by sanding and post-processing, rubbing it with a little mineral oil does wonders to restore the color and give the print a nice sheen. Doesn't seem to do any long term harm, and the effect lasts (at least I have some pieces on my desk that I oiled months ago, and they still look great!)

I use some food safe mineral oil intended for sealing wooden cutting boards (coz that's what I happen to have lying around at home).

Morag - the fbrc8 Thingalump

It's worked with several different PLA's from different manufacturers - but really brings out the best from metallic plastics!

Mineral oil is a bit of a catch-all term for several related refinery by-products:

Specifically, I used this:

I have no idea if it works, but it seems Baby Oil might work just as well (and make the print smell nice :-) )

Personal experience; olive oil can smell/taste weird after it goes rancid.....

Mineral oil is cool since it doesn't spoil (to my knowledge). Olive oil might be fine though, care to test? :)

Yeah, my thought was that olive oil might not hold up well over time. This bottle of mineral oil that I have will probably last me many years, but if I ever run out, perhaps I'll try other oils :-)

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
