Best CD lens cleaner


Any suggestions on the do it yourself cd lens cleaners?
I'd like to buy one in order to maintain my gear.
But I'd like some feedback if anyone knows of a cleaner that works.

Are most lens's easy enough to get to by just removing the cover? I have a Sony SCD333 and it it probably due for a lens cleaning.
Thanks, John.
Sony state in their service manuals that the only acceptable method is compressed air.

Regards,
I have a Sony 9000. Should I remove the cover or try to blow hte compressed air through the open drawer?
