I am about to give my slope front Keymatic a make over. It is missing a motor but I want to smarten up its appearance.

This washer has its (probably original) pale blue door boot, I believe the blue ones are very rare now. It is still in good condition, though it looks grimy and discoloured. The machine also has a rubber filler strip where the front panel meets the top and side panel, this grey rubber moulding is aged, it has lots of fine cracks and isn't very flexible.

What do you suggest to clean up the rubber pieces? Is it possible to do anything to soften the rubber and make it flexible again? Will anything fill the fine cracks in the grey trim? Or just clean it up and then use some automotive plastic or rubber trim rejuvenator?

Thanks for your suggestions...
