Yeah, but that's for extreme cases...like smokers in the house.
For a quickie, a bottle of compressed air with few jets, and that Allsop disc is ok.
Lol, it's not effective! Sure it is.

* I was looking for a video with laser lens cleaning, using a Q-tip and isopropyl alcohol. They're all blurred and not great.
Then I stumbled into this:
The three small screws; I still have to play with them in trying to fix my Panasonic DMP-BD55 BR player...it won't read Blu-ray discs.
...And using no oscilloscope because I don't have one.
By the way, it wasn't necessary to close the other thread. :b ...But that's ok because there are zillion more things to talk about in our music hobby.
And I played some Prince CDs today. Wow, unbelievable the revolutionary music I was listening back then! It's all good, these were the times, a period in my life, and there's nothing wrong with that. Bob Dylan and Neil Young and the Rolling Stones and Van Morrison have been making music for ages and still do. Their musical evolution and experiments we followed and still follow them today...after five decades plus!
Looking @ them two videos above, I kind of feel much more secured with a good solid turntable to spin vinyl.
Look @ those flimsy laser disc players, it truly looks like mickey mouse from the outer space. Look @ all the little plastic parts; it does not inspire confidence. /// The laser disc assembly and transport I'm talking about.
I cleaned many laser lens with a Q-tip and 99% isopropyl alcohol...that's very easy...and it helps bad trackers.
But I never adjusted those three little screws, so some of my players they don't play no more.
And CD transports parts they can break, like the disc clamp, or the springs, or they need lubrification (grease) on the moving rails.
I fixed tape decks, turntables, and I had better luck fixing those than digital components.
That has been my experience sinne very young...starting with transistor AM radios.
VCR machines are a little harder to fix; sometimes best to get a new transport mechanism. But they're gone now, like AM transistor radios.
Yep, this hobby is fun, but not so much for people who have all their music stored in their hard drives. When that PC goes so is all the music without another PC.
Regarding those CD lens cleaners with small little soft brushes; they are a quick helper if it's mainly to dislodge a piece of dust, fiber out of your lens.
Blowing air would do too. But if you smoke cigars your lens will get brownish and better remove the top cover and remove that brown tar/fog/cloud glued to your laser lens. You'll see that brownish residue on your Q-tip after cleaning it. That is the worst case scenario from a dirty lens, and requires alcohol.
But just for normal dust, a tiny piece (minuscule) of dust particle, air fiber that fell on your lens, you can use the fast forward button to make a CD spin faster and often it'll get rid of dust particles. ...Fast forward when in pause mode, then fast rewind. Or a blow air atop the lens when the disc tray is open with a small plastic tube extension attached to your air compressed can.
You can even blow inside with your mouth next to the disc tray opening; a good strong human air blow from your lungs.
• My own prediction: If that thread wouldn't have been closed, I bet that it would have eventually reached 500 and even 1,000 pages. :b
We're a funny bunch; we go deep into our audio subjects...and I like that.
