I'm using 14% volume (the strongest I could find) with a tiny amount of that oxy stain remover stuff mixed in but, due to poor weather conditions @ the moment, it's a slow process..this particular figure was very clean & white, apart from a pink felt tip pen stain on the back of his leg, which after a weeks submersion is slowly but surely fading.
I've had success with about 5 Stormtroopers so far, during last months bright sunny warm spell, it took about a week to remove the (admittedly slight) yellowing..I think Chopper's experiment took a fraction of that time thanks to his geographic location.
The poorest result so far, is a a figure who had dark (almost pink) limbs, the process has worked to a great extent, he's far cleaner & fresher looking, but after about 3 weeks he still has a noticeable pink hue, I'm putting this down to unstable plastic used in manufacture.

- Pink limbs variant?

I've only tried this with Stormtroopers so far, nothing with sticky labels or other strong colours & can report no serious damage to the black painted on details, or comment on any long term bad effects to the figure.
The peroxide cost less than £5 from Sally hair supplies,

must admit I did feel a bit embarrassed trying to explain what I needed it for to the nice (& very helpful) lady shop assistant

, but @ the end of the day I'm now the proud owner of 6 minty white Star Wars figures
