Retrobrite, it's recommended to spray them with a light sealant like

Same thing used in some art communities to protect paper projects,
paintings, etc.

Frankly, that seems a bit much. Given that there
are ways to reverse
that yellowing if it occurs (google "retrobrite" for more info), I'd
say that simply limiting exposure to UV is an adequate measure. If
things happen anyway, at least you'll know it can be fixed.
There are a number of articles that have been published by
conservators for museums that limiting UV exposure doesn't prevent
the degradation of plastics.
Indeed, it's a big headache now for museums and no one's come up with
any satisfactory answer to the problem. ?Cold storage at least slows
the process.
