[Homebrew_PCBs] Rubbing alcohol

2005-07-26 by Robert Hedan

What's the difference between 70% and 99% isopropyl alcohol?

I uesd 70% yesterday (cause I didn't have 99%) and I'm wondering if it left
an undesired deposit, thus disturbing the toner adhesion.

70% IPA is often sold as rubbing alcohol and may contain a bit of lubricant oil.  That will wipe out toner adhesion.  Read the ingredients.  Anything besides isopropanol and water is bad news.
