I have a case that has a plastic piece on the back that is giving me a rainbow effect. Some users have suggested sprinkling baby powder to eliminate it. Is baby powder hard enough to scuff the iPhone 5's anodisation?

Isn't baby powder derived from talc a mineral? I'd not take a chance on using that on my iPhone

IT'S TIME TO PUT A STOP TO THE SENSELESS SLAUGHTER OF BABIES FOR PRODUCTION OF THEIR POWDER!

How many more babies must suffer just so that we can have their soft, white powder?!

I for one will NEVER use baby powder so long as I live.

SAVE THE BABIES!

(oh, to answer your question with a question -- Is it really worth risking scratching up your phone just to eliminate a "rainbow" effect that 98.6% of all people probably would never notice?)

Don't know, but if applied outside will make the phone more slippery. U maybe fixing a little no-problem to a bigger problem.

I'd be curious to know how baby powder is supposed to fix thin film interference.

Dunno but the makers of the OtterBox and others have recommended it for years.

It's not talc powder though. You use baby powder that is cornstarch based.

It works great. It only takes a tiny bit for it to work .

The powder just separates the case from the phone back. As long as they don't touch you won't have the optical interference.

But who wants to look at powder! I'd rather have the interference. :confused:

Lol, all your responses made my day! :D

Yes, i read that it fixes rainbow effects on cases as suggested by Otterbox. The difference is that the rainbow effect can be caused by either a plastic that is not completely of the same thickness as in a screen protector or simply moisture trapped between the protector and the phone. I'm looking for a fix for the latter.

a light dusting of baby powder fixes watermarking and is not visible while in the case...no damage to screen or housing...and by light dusting I mean light not like how you would powder a baby's bottom or flour a counter top while making dough

it works, its fine and its not visible

Yes, if you use the quill of the feather

Out of morbid curiosity, how'd you come across this thread from over six years ago? Were you reading that far back? Do you have first hand knowledge of scratching buffalo skin, were you searching for baby powder? Seriously, genuinely curious. Welcome, by the way.
