Righto tech buff's! I have a pair of Green MX 1000's which refuse to lose their colour!

I have tried the strongest paint stripper from my mates body shop? every other paint stripper you can buy etc

Super strong thinners?,gasket stripper and even brake fluid

they have lost a little bit in places,but this is driving me mad!! dont want to scratch them up by using abrasives' so do you guys know what I can do?
