I've heard for years that we must always use ammonia free glass cleaner. However, I can only find one reference to this in Paul Fredrick's classic book. Many other books "glaze" over the glass cleaning process.
I'd like to see some hard proof that glass cleaning products containing ammonia cause noticeable damage to artwork. Wouldn't the cleaner evaporate before causing noticeable damage? Are ammonia free products really THAT important? I'd like to hear some horror stories about the catastrophic effects of using ammonia glass cleaners.
I just want to make sure that I'm making a decision based on facts.
