Blu-ray Lens Cleaners: Need Some Help

[kemcha]

I need some advice about cleaning my Blu-ray player.

About two years ago, when I purchased my HDTV and Blu-ray player, my DVDs would play perfectly with no problems. However, I've ran into a recent problem. While my Blu-ray disks play with no problem, my DVDs, well, some of them, are starting to skip in the Blu-ray player. This only affects some of my DVDs and I've determined that the DVDs play fine in the DVD player in my desktop PC but pause while they're in my Blu-ray player.

Does anyone know a safe way of cleaning a Blu-ray player or who can recommend a quality Blu-ray/DVD/CD disk cleaner?
