Need help removing discoloration from a brand new clear TPU case - General Questions and Answers

I just bought a Nillkin Clear TPU case for my phone and after a few days, I noticed some blue and red discoloration near the power button. How do I remove this without damaging the case? The red spot is probably ink, but I don't know. The blue is probably from my denim jeans (though in a few days of use, it shouldn't have discolored that quickly) or from the blue microfiber cloth that I use that bleeds dye when wet.

Steal a new case?
TPU by nature absorbs things, but doesn't release them easily. There really isn't way to bring it back to the original white color.
I bought a clear TPU case that turned a dingy yellow in about a month. My advice, only buy darker colors if you are getting tpu.

AJerman....that was funny lol I think that's my best option seeing KindaTired's response lol thanks to you both
I had one and Tried about everything too. I had on with white sides and a clear hard back. After everything I tried brake cleaner. The break cleaner seemed to work, but it made the back hard plastic crack. Mine was turning blue from my jeans. It took the blue off but left the ugly yellowish color still....
www.handhelditems.com has a lot of white tpu cases. they were $4 when I bough them and I decided to be 5 so when they turn nasty i throw them out. hope that helps
I'm actually looking to dye a translucent TPU case from clear to black. Does anyone know if there are dyes that will absorb into and not bleed or rub off of TPU? I don't want something that will end up staining my clothes when I put in in and out of my pocket.
ESdesigns, just paint the inner side of the case with acrylic paint and a few coats will make it solid black (or any color really). After that make sure to use some clear coat over the paint to protect it, and thats it. And if you wanna keep it clear but tint it with a certain color just use ink or semipermanent hair dye (like manic panic, arctic fox, stargazer, etc) and again just apply a coat of the coloring on the inner side of the case and leave it for like half an hour, maybe an entire hour to be sure, then rinse. It'll be tinted but will remain clear.

Incipio Dualpro White Case Discoloration

I picked up a S4 from a corporate store last Thursday on release and grabbed the Incipio Dualpro case in white with it. Unfortunately I've noticed a pink discoloration of the outer shell already starting to occur around the parts that my hand comes in contact with the most (i.e. near the power button, below the camera, etc.). This is my first Incipio case, so I was wondering if this is a known issue or if there's a way to clean it (wiping with water isn't making it a difference).
The material of the outer case is marketed as "Plextonium" (some sort of polycarbonate). I'm an engineer and don't really come into contact with any strong chemicals so I believe the discoloration might be from natural oils in the skin. The phone is kept in jean pockets whenever it's not in use so I don't think it just rubbed up against anything (the fact that the discoloration is on the parts I touch most often also supports this).
This is quite a shame as I actually really like the case otherwise.

Something to consider regarding the Orange neo

I just scratched the orange plastic top cover of my new Wild Orange Neo, and it is white plastic underneath a thin coating of orange color. this is disappointing, because I chose plastic over the metal one so I could buff out scratches when they occur. With regards to normal watches, I like stainless steel cases the best because I know how to remove any dings or scratches in the finish. I typically do not buy any watch with any type of coating on the surface which prevents you from being able to refinish it.
One thing that strikes me as odd, is that the lower half of the case looks like it is solid orange, not coated orange.
****** It appears, thankfully, that I was technically wrong about it being white plastic underneath a surface coating. After studying both the orange and black ones after scratching them, is that the plastic is of the type that turns white when scraped. As long as the remaining surface is rough or little edged of it are sticking out, they appear white. You can remedy that with 600 grit wet or dry black sandpaper (or any other favorite watch case refinisher that you are used to using). It just needs to be a smooth surface again, to prevent it from looking white. ******
I feel much better about them now. Sorry about that. (I don't however, like the ease with which the bodies are scratched)

Nillkin PE+ Blue Light Resistant Tempered Glass Screen Protector

I know the thread title reads like click bait, but I received the aforementioned screen protector today. When I bought it I could only find one review of it anywhere (I believe it was a Sony Xperia thread on XDA) so I thought I'd post my thoughts.
Nillkin screen protectors are pretty well documented elsewhere, but you receive
A wet wipe
A dry wipe
A statically charged plastic strip
A microfiber cloth.
You wipe the screen with the first two, and remove any dust particles with the strip. Microfiber cloth is for pressing down the protector and cleaning the protector.
If you get one make sure to put it on with your case on though. My first one (regular PE) was put on when it wasn't, and the case kept lifting the corner off and it eventually cracked as a result.
Fit and finish is fantastic as all the Nillkin protectors are. This particular one has chamfered edges though, also known as 2.5D. Gives it a really slick look, kinda like the Galaxy Edge.
Anyway, about the blueness - when the screen is off it looks like the backlight has been replaced by a UV light. It's extremely obvious in direct light on a dark screen too. But if either of those are false, it's not really noticeable. I'm sure that it is taking some of the cool edge off of the backlight though.
I'm keeping it on for now, we'll see if the blue annoys me (as my phone is dark themed).
Any questions let us know.
I also purchased one of these a while back, it certainly took some getting used to with the change in the glass colouring. My biggest issue and one which I got a refund for was the fact that after about a month the protector started to lift from the phone, starting around the button and then along the sides. I spoke with Nillkin regarding this and they refunded my purchase which was great, I did then purchase another and also the Sparkle case too which is great as well.

For those of you who are still interested in this protector: only buy if you intend on using it with a case that covers the top and bottom of the phone completely, or if you never have any items in the same pocket as your phone.
Mine has cracked in the same place as the non-blue protector (upper left corner), and I have narrowed the cause down to my phone knocking against other items in my pocket.

Yellow color solution in fusion ringke or spigen neo hybrid cases?

Hello I have little time with the Galaxy S7 and barely bought it I thought about having the Ringke Fusion case that I had on the Galaxy S4, I loved being able to customize the back part.
The detail is that I see people say that the transparent becomes yellow over time by the material used in the edges of ringke or spigen, also in black for being the same material, I do not know why they did not remove this model also as in the s4 without that rubber and directly from another material.
Now my doubt, someone got yellow?
Was it in a short time?
Someone tried to take away the yellow with methods like YouTube to put it in baking soda and lemon juice?
And the most important doubt, I would not like to be buying a new cover every so often because it turns yellow, it can be painted with black spray for example, and the paint does not fall? I say it for the material? Only the edges protecting the glass on both sides and the inside of the edges so that they are not painted?
Sorry for my bad English.
Thanks and regards.
