"Bacterium is attracted to moisture and loves to grow in the nook and crannies of a loofah..."

9. You'd have to use A LOT of soap and really work it thoroughly through.

For example, washing your hands cuts down a bit on bacteria. But there's still tons left on your hands. Think of it this way - you see doctors on TV shows "scrubbing" before surgery, and even after that extreme effort they put on gloves.

If you happen to be concerned about germs in a loofah or other scrubber, best way to deal with them would be to soak it overnight in a bleach solution every so often. Monthly would probably be plenty - we are built to live in a world full of germs, so it's not that much of a threat.

Scrubbers made of artificial materials (ex. brush with nylon bristles) will harbor less bacteria than natural products.
