Cleaning with alcohol is good, but don't waste your money at a pharmacy. Methanol (wood alcohol) is available at any hardware store in quart or gallon cans and it's a LOT less expensive that way. If you're planning to do any brake line flushing or other internal cleaning, stay away from any kind of petroleum-based solvents such as mineral spirits, etc. Petroleum does not play nice with rubber parts in a brake system.
