Can I clean my iPhone 5 with windex

The back of my phone is really dirty (iPhone 5) can I just put some windex on a paper towel and use that on the back?!

Yes, just be careful not to get it in any open ports such as the volume speakers or head phone jack.

No because a iPhone is a lot thicker

I would check make sure there wasn't any bleach in windex. If there's I probably wouldn't use it but if there isn't then I would. You should get you a case for that phone. I've had mine in case since the day it came out and I have only taken it out one time and there wasn't a speck of dust or anything on it.

Just use a damp napkin… Not wet.
