Yellowing of systainers and Cleantec

[Serin8]

If anyone gets annoyed like me over systainers and their cleantec turning a disgusting yellow, I found that goof off and a pressure washer (1800 psi at least) is the best bet to remove that yellow. 

The yellow actually strips like paint.

I am happy I put in the hours of work to get my CT looking good again. It no longer looks like an 80's vacuum I fished out of a thrift store barging bin.  It looks beautiful as it should.

Pride of ownership is indeed a wonderful thing. Sadly my 30-odd Systainers work very, very hard for a living. The best I ever get time to do is to give them a wipe over with a damp cloth and a little detergent when they reach this stage [sad] It at least makes them presentable again. Black, anthracite and sapphire blue are the worst because they show up everything.

I also found that Peroxide from a hair salon supply place, slathered on the plastic, then let it sit out in the sun, works great. I had done this on some classic sortainers i got for a bargain.

Some tutorials show wrapping them in plastic wrap, but i found this unnecessary; i felt it was easier to just go outside in 30min to an hour and just slather some more of the peroxide on, than to deal with wrapping plastic wrap on a slippery systainer.

It was this stuff I believe, cheap:https://www.sallybeauty.com/hair-co...-kUIG9gZqvau25vI2yxoCgh8QAvD_BwE&gclsrc=aw.ds

Then just rinse off when done. I originally saw it on a video way back when for people restoring original Nintendos.

I have never experienced this issue. What causes it? Time, sunlight itself, etc?
Mine stay inside stored in some shop-made Sysports.
