Question about Vendesign Canisters Yellowing

[Dougster]

I have purchased some older Vendesign machines and due to time, sunlight, and oxidation the plastic canisters have turned yellowish. I read somewhere that headlight lens restorer could be used to buff it out.

I tried it and it did not work! I used 2000 grit sandpaper and it destroyed any hope I had to make it clear again. I hope someone can help me with this - I hate to have to replace these canisters just because of this.

Thanks Much! Dougster
