Here' a tip from an American PhD chemist: All plastics oxidize when exposed to oxygen (especially noticeable over over long periods of time). The air we breathe is about 20% oxygen. Oxidized plastic is yellow. If the plastic handles were originally white then this oxidation shows up as a yellow discoloration in the plastic over time. Dark plastics, in fact all consumer-grade (inexpensive) plastics oxidize but the yellow discoloration really shows up on a white plastic or light plastic backgrounds. Depending on the type of plastic usually [1] removing the plastic door handle and [2] soaking it in a mixture of 50% vinegar (acetic acid) and 50% distilled water over night will make it white again and it will look like new. After thoroughly drying the handle (24 hr in a warm place), three very light sprays with a clear coat spray such as 'Rustoleum' clear coat spray or equivalent ('Painter's touch' clear coat spray; 'Tremclad' clear coat spray, etc., or any equivalent clear coat spray) will keep your white door handles looking like new for at least 2-3 years. The clear coat spray isolates the plastic in the white door handle from the oxidizing atmosphere thus preserving the plastic's color.
I just whitened mine. With hydrogen peroxide and used enough baking soda to make a paste. Smeared it on left it for 11/2 hrs and white as new.
