We use alcohol to clean the antislip coat of finished Crysal single vision lenses once they has been edged. But, the antislip coat is not ease to remove and some lenses scratch. Is there a easier way?

I use an Ink Remover I find it works best. Inland or Dynamic's Eliminator are my two favorite, very safe on Poly. I hate the greasy ones - as far as I'm concerned oily things have no place in a finishing lab!
I have no idea what you will be able to get easily in Panama from your distributors.
It is a pain in the butt to get off.
We don't use Cryzal, but the Zeiss Duravision top coat wipes off easily with just the disposable cotton wipes from Hilco. We try not to use any chemicals. For stubborn top coats, we use Ink Remover from Delta Optical, but any non acetone remover will work.
We we also use a no slip spray from Quantum on our in house AR. That wipes off easily with the Hilco cloths as well.
The longer the top coat remains on the lens, the harder it is to remove.
Been using alcohol pads for over a decade with great success.

One of my biggest pet peeves are AR lenses mounted in a frame with a subtle purple ring around the outside that will quickly get filled with oil and gunk that the exposed hydro and oleo coatings push towards it. Take the dang lenses out, clean the protective purple coating off and remount them before saying the job is final inspected. That really gets my dander up, and i have a lot of dander though it takes a lot to get it up, but once it's up, boy howdy watch out!
I've used Viva paper towels forever to remove the anti-slip coating. ( And no, Viva won't scratch your lenses if you're using a premium AR) I've been told chem's like alcohol will damage/shorten the life of Hydro/olio coatings.
I don't understand the hesitancy to use ink removers on lenses during finishing? Surely a quick wipe. On either side of the lens isn't affecting fresh hydro coating is it? I wouldn't tell a customer to use Eliminator every day to clean their lenses but one time during finishing? Works too well for me to stop unless I see negative results which I haven't.
To each their own, but for over 20 years since these ( Essilors) anti-slip coatings have been out, zero scratches. Keep in mind most lens scratching is from pressure aggression cleaning. It doesn't take much pressure to wipe the coating off. Doubt it, try it. Less loss of hydro/olio coatings.
Acetone free nail polish remover.......it costs like $1.00 at CVS.
Depending on the brand, I noticed with my Zeiss lenses, I had to use alcohol or ink remover, but Shamir for instance, it's way easier just to rinse the lens under warm water and give it a good clean. I'm with Hoya now, so I've had to go with markaway. Any Crizal lenses we have are usually finished stock, and I find the water method works fine
-Poly is the best substrate for coatings.
-Poly is extremely scratch resistant.
-Poly is extremely impact resistant.
-Poly is unparalleled in clarity.
-Poly is much lighter than traditional crown glass.
Like poly, you can trust me about 40% of the time.
I've never had a problem with simple rubbing alcohol and tissues.
I'm Andrew Hamm and I approve this message.
The water content of rubbing alcohol probably makes it okay, but pure Isopropyl on poly and even 1.67 can cause coating adhersion problems because it absorbs through the edges.
I love my eliminator, that stuff is the best. Im sure warm water and dawn works too though. Eliminator is fatastic on facial oils also
You should always use soap and water to remove any non-slip coating. Acetone, alcohol, or any other solvent based cleaner will ultimately damage the hydrophobic that is underneath the non-slip layer. This will in turn lead to warranty returns much sooner than you are hoping to have them.
Chris Ryser's Markaway and Kim-Wipes.
About 15 - 20 years ago, one of the trade magazines did an article on cleaning a/r coated lenses. They simulated thousands of cleanings using everything from toilet paper to diapers to soft t-shirts. The only two things that did not scratch the lenses were microfiber cleaning cloths and Bounty paper towels. I use Bounty to remove the film. Just a very gentle wipe and it totally disappears.
Essilor sell the own lens cleaner "Essiclean anyway I use alcool
"denatured ethyl alcohol" I can buy it at the Pharmacy or many mall.
Interested party here as well.
I am not a fan of Kim Wipes. The anti static properties make them ideal for cleaning dust and grime around circuits, but I find them way too abrasive for lenses. I like Hilco's cotton fiber disposable towels for wiping the anti slip film/spray. I find that they clean all the anti-slip stuff off on lenses without the use of chemicals, and without scratching lenses.
As for Bounty paper towels, never tried them, probably never will. No wood fiber products near my lenses......but I can be convinced, as long as there is enough reputable proof against my anti-wood product bias.
And I am going to skip the Super-Bowl Officiating will suck and will go against Philly by at least 5-1 (penalties in favor of NE). I might tune in for the commercials, but based on last year's commercials, I think I would rather watch Netflix with multiple IPAs in hand.
Here is a PDF of the article. It seems to be from May of 1999 by John Young, the founder of COLTS laboratories. It would be nice to see what it looks like with modern coatings. I would assume today's coatings would fare much better in the cleaning materials category and probably similar to the '99 coatings in the solutions category.
