this is timely as I'm just about to run out of the vallejo airbrush cleaner I started out with. is using isopropyl alcohol (either 70% or 90+%) as a cleaner a bad idea? I recall reading somewhere that cleaning with acetone could eat rubber seals in the brush; not sure if alcohol would cause the same kinds of problems (on a side note, I'm not even sure if my brush *has* any rubber seals in it...). the vallejo cleaner, while it works well, isn't exactly cheap
looking forward to the paint thinning episode.
