It's ok to get water on her and in her if you make sure she dries thoroughly afterwards to avoid rusting in the future. All my ponies come second hand and they usually have their neck seal broken, so to make sure she dries thoroughly, I pop her head off and put her on a paper towel near a window for a few days to dry. Besides the eyes, you can wash her normally For rusty eyes I just use toothpaste, a toothbrush, and a toothpick. Using the toothbrush, I scrub the majority of her eyes with toothpaste, then get the harder parts with a toothpick, minding her eyelashes. Then I rinse off the toothpaste. Some people use rust remover, but I never have, so I'm not sure about how to use it

Yeah, at least it helps a poor discolored pony for a while

Eldarwen, I'm glad it works for you, but in almost everybody's else's cases, it has damaged the pony rather than helping, and can damage other ponies too. Also, how do you "use it carefully"? I'm curious KottonKandy, you might want to try hydrogen peroxide? I don't know if the ponies who burn while sunfading burn in the hydrogen peroxide treatment. Here's a link to info on it http://www.mlppreservationproject.com/body.html#Yellowed
As another possible alternative, maybe you could try an OxiClean bath? I have never done one, so I don't know much about them, but I do know they remove grime. Since you said it was a grayish color, it might be mold? (Lol I have no idea. Still learning ) It might have gotten through to the outside like how sometimes rust shows through to the out side of the vinyl, or stained the vinyl. It might have been growing on the outside and stained the vinyl or receded into the pores. Or it simply could be grime that got into the vinyl. If so, an OxiClean bath would probably help (if you can give baths to brush n grows.)

Yeah, I agree. It's so frustrating

She is my favorite pony of all gens! (Hence why I drew her as my avatar) Sadly, I don't have her at all. If I had to choose a version, it would probably be the US and Sternenglanz because I can't choose The US version is beautiful, and Sternenglanz has such wonderful colors and that beautiful pose that just make her sooooo pretty

I actually downloaded the game, and it was pretty fun! For a while... until everyone I played against had a Deoxys. Then it was really frustrating and I couldn't win at all Don't get me wrong, the game was awesome and really fun to play Up till the point it where it was basically telling me I had to pay to win. I think I would prefer a Pokemon Go style game though, because ther is no pony violence  Just my opinion though

you mean more people wandering into traffic and in front of trains, completely distracted?

or you mean players trying to trespass on private property to "catch" the items?

short answer:  NO NO NO, get the &$@_@@ off your phone and join the rest of us in Reality.

Playing Pokemon Go doesn't mean being completely distracted or trespassing. When a Pokemon enters your area, your phone vibrates, and you can move closer to it, occasionally glancing at your phone to see if you are close enough to catch it while being aware of your surroundings. When you are close enough, you can throw a poke ball at it, and move on You can still be aware and alert while playing, because the app allows you to do so Though there were some safety concerns and people breaking the law, I feel like the app took the blame, not the people who broke the law or were putting themselves at risk without the app's instructions. (The app actually gives safety warnings and doesn't allow you to play if you are moving at a certain speed to prevent car accidents.) If a pony version of Pokemon Go was made, there could be on option to turn off moving in the game by moving in the real world What I mean is that you could just move in the game world (which could be Ponyland!) and catch ponies there.
