A trusted cleaner wrecked a classic lens I was fixing.

I used a well known alcohol based solution on a vintage lens. It ate into the coating and now the lens is unusable. Is it time to stop telling new repairers to use this stuff?

Saw a video saying alcohol can dissolve old coatings.

Maybe the real problem is assuming all old coatings are the same material.

Honestly, that alcohol solution really cleaned up, @elliot836.
