Yeah, it has a high acidic pH. Same with any form of alcohol. Stick with the naturals, baking soda and lemons.
Goto Home Depo, Lowes, Wal-Mart, (Is ACE Hardware stores still around?) or any Hardware store and grab a stainless pipe cleaner, it will get off anything in side that stem with a little bit of elbow grease. Good thing is they are cheap! Maybe a 1.25 at the most. They also might carry the plastic pipe cleaners, which is good if you have a plated stem. If you have damaged plating go with the stainless, because exposed metal is just going to get worse in terms of corrosion and holding flavors.
