Backup Camera Issue

[jdaddy33]

Has anyone else had issues with their backup camera looking blurry. On my display in the truck I get what looks like blurry spots, but when I get out and I go back and clean off the lens it's still blurry. At my first scheduled maintenance I brought it up and they replaced under warranty. Well it started happening again and I brought it up again, this time the tech said "problem wasn't present at inspection" - which is BS. I was thinking it was maybe a seal issue, because I just washed my truck and I believe it is worse, I was able to capture this photo which makes it almost look like a residue. I tried some "goof off" and a variety of class cleaners to no avail. I'm thinking it has to be on the inside. But I can't understand why it keeps happening, even after they replaced it once.

As an old cameraman who's cleaned plenty of lenses for a living, allow me to offer some humble advice. 

 

Glass lenses are pretty durable but sometimes the coatings used on them are not.  I don't know what the lenses for the backup cameras are made from, most likely plastic so they may be even more fragile.  I definitely would not recommend Goof Off or ammonia based cleaners like Windex. Many solvents maybe harmful.

 

If you get a new camera, I'd recommend some plastic safe cleaner. I use Novus 1 on my motorcycle visor and it works good. One thing to remember is to try to blow or flush off any grit or dirt on the lens before you clean it. (I use a dampened 100% terrycloth towel to loosen the bugs before I clean it.) Otherwise no cleaner can prevent the lens from being scratched.

 

Good luck and I hope this helps.
