Are CD lens cleaners (disks) B.S. or effective?

i find this question a little odd since you have said that you have been in the hobby for quite a while.

I am sure that you have read comments from others over the years where members have given their input on these.?

I had a cleaner pad and fluid if I experienced a skip. I noticed no improvement with just cleaning. I used the fluorescent green edge pens… those I’d help improve the sonics a little bit… stray light bouncing around I am sure.

Never had to use one in 40 plus years.....
