Best way to remove dust stains from white plastic figures?

[CK74]

     Hello. This is my first post on the forum.

     I have a Yamato 1/48 Roy Fokker that was sitting on a shelf for the past 10 years or so, and over that period of time has collected a large amount of dust.  I went over it a few times with dust cloths, and have found that while the dust has been removed, the figure is now an off-white color.  It hasn't yellowed with age, it just looks ever so slightly grey.  

     Would rubbing it down with Windex help? Vinegar? 3% peroxide?  Id hate to make it worse somehow.  

     Thank you for any information.

Post a picture.

it might just be residue. If you want to clean it well use a clothe dampened with warm water and dish soap. Not need to rub it in. The warm water and soap should lift off the grey.

Sounds good, thanks.
