DVD player lens cleaning

My grandpa's dvd player started having a "no disc" error on all the discs he tried, even new and unscratched dvds. I could hear the dvd spinning, so I knew the problem wasn't the motor. I figured the laser pickup lens was dirty, or dust had fallen onto it. I tried blowing into the dvd slot, but that didn't fix it. The solution was to take it apart to clean the lens directly.

I first tried cleaning the lens with rubbing alcohol using a cotton swab, but that didn't solve the problem. It turns out dust got trapped underneath the lens, not on the surface. Blasting it with an air duster can did the trick. One of those lens cleaner kits would not have worked for this specific situation.
