So I did check the ingredient list on the 3 different bottles of rubbing alcohol I have around the house and all list only water as the other ingredient. Curious, I got on the web and did a google image search on 'rubbing alcohol labels' and the only time something other than water was listed was if it had a small amount of methyl salicylate (wintergreen oil). This was looking at about a pretty wide variety of labels. So unless the labels are wrong, the majority of rubbing alcohol sold is just alcohol and water, nothing else.Rubbing alcohol frequently contains other ingredients which are not compatible with a good bond. Check the ingredient list.
Yeah, rubbing alcohol is made for rubbing - you know, massage. As such it usually contains oils or perfumes or other things that make for a good massage but would definitely NOT be good for use as a cleaner.
These additives would contaminate any surface you were trying to clean.
Kind of the other way around - rubbing alcohol is usually isoprpyl alcohol with additives. Quick chem lesson - methyl alcohol (methanol or wood alcohol) has one carbon atom and is quite poisonous. Ethyl alcohol (or ethanol) is the drinking kind and has two carbon atoms. Denatured alcohol is ethanol with something like a bit of methanol added to make it undrinkable. Isopropyl alcohol is one of two kinds of propanol, which has three carbons, and the alcohol OH is connected to the center carbon. If you attach it to an end carbon, it becomes n-propanol, which actually has different properties than isopropyl. The interesting and really useful trait of alcohols is that the can both act as an organic solvent as well as an ionic (water soluble) solvent. Yeah, I know - way more info than you wanted!
