You are brave to recommend these !

IMHO, if you want to do no good at all at best, and actually damage the
laser at worst, use a cleaning disc with little brushes on it ... On several
occasions, I have seen an otherwise good laser wrecked by the brush getting
caught in the lens suspension, and tearing this off with the high rotational
speed of a DVD.

Don't tell me that But since a laser cleaning CD kit is a 'CD'
wouldn't the DVD player use the rotational speed for a CD?
