i am looking at doing some injector cleaning in my basement this winter. i used to do this in the garage at my old place using b12 chemtool with good results. now i will have to do it inside in an area where chemical smells and flammable liquids will be a problem. my question is can i use a non flammable mix of regular rubbing alcohol (50%) and injector cleaner to clean them with and not cause any rust or other problems with the injectors if they are stored for long periods of time? is there a non flammable injector cleaner out there? something that will not stink up the whole house?
