toilet
I moved into an apartment, and found the toilet seat is yellow, which I didn't notice before moving in.
The landlord said the toilet seat turned yellow because of the sunshine, and had been cleaned.
Is what she said true?
What can I do about it?
Thanks.
The caps come with a washer-type thing that they clip into:
Your toilet clearly does not have these clips. Using silicone is most definitely not the correct way to attach these, so maybe the installer lost the clips or just has never installed a toilet before?
It's normal to cut the bolts to length, as the length needed depends on the thickness of your floor. The nice way to do this is with a tool that has a cut-off wheel (eg, Dremel), the not-so-nice way is a pair of cutters since it leaves the edges sharp, but if the cap is attached correctly it shouldn't matter.
Here's what it looks like normally (via Handymanhowto), the clips are clear in this case:
Regardless of how clear the drain lines are, if you have blocked, obstructed or inappropriately sized plumbing vent stacks, the bubbles could be emanating because the air being displaced as the drain line fills from the shower, have no easier path of resistance than your toilet.
TL:DR You've cleaned and investigated downstream, maybe it's time to look upstream.

Yep, sunlight will definitely change the color of plastics. It's the UV light, which is invisible to you, but also causes your sunburns.
I'd imagine you'll be cleaning this on a more or less regular basis yourself with some kind of disinfectant. I'd probably disinfect everything (a mild bleach water solution would do nicely) immediately upon moving in, just because.
If you really hate it, you could always try demanding that the landlord replace it, or you can find a replacement pretty cheap, like this one for $14 at Home Depot.
If you replace it, it'll probably turn yellow again eventually, but it'll happen slowly and you'll either have moved out by then, or will have grown to accept it as yours, or you'll just replace it again with another cheap toilet seat.
I wouldn't worry about it from a sanitary standpoint, though. :-)
