How can I stop the white plastic from "yellowing" after a few years?

You can't. This is cheap old plastic that is not UV-proof. It may have some UV inhibitors but over time the lens will yellow. The more sunny the climate, the faster the process. My brother-in-law has had one for over 10 years and it still looks good. His is on the south side of the house.

I don't believe there is anything you can do, except perhaps make sure you mount it where it will receive minimum direct sunlight. Plastic ages faster when exposed to UV light. One might try coating the plastic with a layer of UV resistant plexiglass, which may delay the aging process. Or make the thing out of glass. Nothing lasts forever and there are always trade-offs.

The plastic has a yellow tinge to begin with. It's not really "white" at all. From seeing older ones around my neighborhood, I doubt that they will yellow further.

http://www.howtocleanstuff.net/how-to-whiten-yellowed-plastic/ I tried to use a lot of bleach and that worked on other items that have yellowed. I have not tried bleaching it in sunlight/UV light, but I heard that works for some people. My mat has not turned yellow yet, so I haven't tried anything for this particular item.

Give them time and they should come around, if not try moving it to different spot. I would not paint the plastic.

I purchased the blue for one of my co-workers & haven't noticed this problem. I bought the white, which is more clear than white, but it has not discolored. I don't think they should discolor in that amount of time. I would hope it would wipe clean, but if the plastic is actually discolored, I might think about an exchange.

I've only had mine 2 months so far, but I highly doubt that it will turn yellow as this is more of a hard plastic design vs. a TPU rubber design.

Jason I would try the best I could to keep it off rubber and plastic parts. If you accidentally get some of this solvent on any rubber or plastic parts simply wipe it off.

I have the same issue and don't think the plastic can be removed. I'd love to hear if someone has a suggestion for cleaning this area out as well.

Unfortunately, the white on mine has gotten somewhat dirty (I also got a pen mark on it which I could only partly get out right away). I haven't tried to clean it yet, but it seems like it's going to require the old magic eraser if there's any hope of really getting it clean. The pink hard plastic is still very clean, however -- might be wise to get a darker color in the silicon.

I've never had that problem. Maybe contacting the manufacturer or seller will help. Good luck!

yeah...all the plastic will eventually start breaking. It just gets brittle over time. Sounds like its the beginning of the end of your dishrack. I limped mine along for several years as it slowly came apart on me, then finally replaced it. The only thing I really miss is the knife block.

Mine does that too! I have had it for 10 years though. It is almost like the metal is rubbing off. I put mine in the dishwasher, so I've always assumed that was why it does this.

There's not many ways you could do that. There are probably some sort of plastic repair kits out there but you would be better off googling that then asking here. Perhaps hobby shops?

My daughter has has this shower head since Christmas of 2012(9 months approx) and still has not had any issues with it. The plastic piece that the water goes through is yellow....probably from the minerals...should probably clean it with some CLR or somthing, but aside from that no isses. Water still is colored rather appears to be via the lights as the lights work fine.

I'm not sure[google it] but it can yellow so I've started using a water base polyurethane.

Yea I had the same question so I asked the seller over the phone. They said the original tip is white but it turns yellowish because of the solution itself.

Since you can't use cleaners I make sure I clean every other day with paper towels and the provided brush for the silver disk. Once you have a build up I do use a soft brush on the white plastic parts,, but NOT on the silver disk. They sell an additive for hard water build up, which may be your problem. I hope this helps.

UV yellowing is always possible with any clear plastic, but scotchguard has been noted as being better than some others in this regard. It will NOT yellow your car, but a white vehicle would make a yellowing film more noticeable. Still you'really talking many years down the road and you can simply remove the clear bra if it did become an issue.... I would guess this would be 8 years or more of protection before this would even be an issue.
