Removing Betadine Solution from Skin [posted
Question: What will remove Betadine solution stain from the skin?
Answer: Bleach, but it also changes the skin.
Question: I am interested in obtaining some information about betadine solution. I
have been told that it is ineffective when put on inanimate objects. Is this true? In
practice we place betadine on the connections to subclavian catheter for 5 minutes. The
betadine remains wet. Is this effective? Although our procedure is to pour unused betadine
down the drain and rinse, many mix it with peroxide and or pour it in basins filled with
vespene. Is this OK or does it cause a potentially harmful chemical? Thank you for any
information that you can send me.
Answer: Hard to tell about inanimate objects. Generally, we assume that they are
still potentially infected due to the crevices and crannies where bacteria can hide.
Betadine or any iodine containing antibacterial will not be effective wet. It must be
allowed to dry to obtain maximum effectiveness. I don't know of any harmful chemical made
by this concoction; but, you're getting out of my field.
