Rubbing alcohol has water and other oils in it, don't use it.
Stephen, I think that this caution has been repeated so many times that people believe it without thinking. Where I live (California), rubbing alcohol is simply 70% isopropyl alcohol (thinned with plain water -- probably distilled water so that Type 1 diabetics don't croak and sue the alcohol company). I've asked two pharmacists about this -- they confirm that rubbing alcohol is as I've stated (which is exactly how the stuff is labeled!). I submit that the repeaters have been confusing rubbing alcohol with Witch Hazel, which is a mixture with more stuff in it.
Are you sure there's still ink the cartridge? The printer does not monitor the actual ink levels.
For cleaning electrical contacts, what is good other than distilled water?

A very expensive and very good contact cleaner. Our Bob Headrick has written here about the coating on HP ink cartridge contacts -- an interesting read. My first tendency is to use alcohol in this situation, but Bob's explanation's got me going for a contact preparation that leaves a thin oil coating behind, instead (rather than one of the other types of contact cleaner/preservatives).

Deoxit is almost amazing how it works - can use it on all metal surfaces that conduct eletricity. Alcohol conductive, so I would use it sparingly. If it gets absobed into any materials, it can make that material conductive (rubber, phenolics, etc.). For connectos and contacts , I ONLY use DeoxIT products. Mike.
Mike A bit OT here but I am interested in DeoxIT to restore some old audio rotary (multi layer) switch contacts. These are extremely hard to reach or I would have used a silver bearing heatsink compound to resurface them (very conductive). Have you any experience with this?? I cannot see what active ingredients the product uses to remove oxidation and restore the surface. This would require a spraying of the controls. Any possible application here?? Thanks!
I do remember using a contact cleaning spray for the old rotary channel selectors on TV sets. I've also use it on electro-mechanical switches on intercom system call boxes. I bought whatever they sold at Radio Shack and it worked just fine.
These particular ones are 30 years old and need something more than the old contact cleaners. Fact. I would literally like to get in there and add some silver powder and have the blades rotate and pressure embed the silver into the contact surfaces to renew them. They were not silver originally but I thought I had just the ticket with silver bearing heat sink compound, but the controls are impossible to get to with it. The amound of disassembly required is unthinkable. Spray required but something active.
