When I recently joined this group, I read alot of the old posts. I
saw in one the mention that Freon-TF, used to clean fans, wasn't
available anymore.
Where I work, they use something called "Freon TF" to clean sensors
on check-sorting equipment. The product says that "Freon is a
trademark of DuPont ... Contents: Trichlorotrifluoroethane".
Is this the same stuff you're talking about or is it a substitute.
If anyone is interested, I can give specifics on where to get it.
