Proper handwashing is always the preferred practice. When that isn't possible, many with COPD regularly use an alcohol-based hand sanitizer. We know there is a nationwide shortage of sanitizer and many have suggested recipes for making your own. While this can be effective, it is a BIG IF because you must follow the instructions carefully and end up with a sanitizer that has at least 60% alcohol. You should also consider the risks of accidental ingestion or contact with the alcohol if you have children in your household and use it only as a last option if no soap and water, antibacterial wipes or commercial sanitizer are available.
