CDP laser problem

My CD player (MHZS 88F) developed a problem: when starting a CD, I sometimes hear clicks, and sometimes intermittent noise. When I remove the CD and clean it with a soft cloth or clean a laser head with a soft brush, it disappears.

I heard that there is a laser cleaning disk/device or something like that, but I also heard that these may be dangerous for a CD player. Do the symptoms I described suggest that the laser head is [nearly] out of order?
