Mack 880
Happy to Stihl be Here

I have an old MS 880 that was given to me, in horrible condition. I'm cleaning it up and saving the parts for a later project. What have you guys found as the best way to "restore" a yellowed plastic handle assembly?
The saw is completely OEM right now, so I'd like to not damage the handle assembly in case I decide to use it later.
