Log reduction

Have you ever tried to clean up a messy room? Sometimes you need to use soap and water or cleaning products to get rid of all the germs and dirt. Log reduction is like a way to measure how much of those germs and dirt are removed when you clean.

Imagine you have 1,000 germs in a room and you clean it really well with soap and water. If you remove 99% of the germs, that means you have a 2-log reduction. If you remove 99.9% of the germs, that means you have a 3-log reduction. The more zeros you have in front of the number, the better the cleaning job.

So, log reduction is basically a fancy way of saying how many germs or bacteria were killed or removed during a cleaning process. It's a way of measuring how clean something really is. Whether it's cleaning your room or sterilizing medical equipment, log reduction is an important thing to keep in mind.
