Review on 71cm Long Flexible Sink Overflow Drain Cleaning Brush for Efficient De-Clogging by Rodney Handy

Update: Turned out to be 18" too short to thoroughly clean my air gap hose and it clogged again. under the kitchen sink and will cause a wet mess if not caught in time. My previous repairs (blowing it out with a paper towel hose or pulling wire through it) were temporary, lasting anywhere from a few weeks to a few months. I didn't understand why until I bought this brush and saw how much dirt it pushed through. and what remains on the brush. A few passes of dish soap on the brush and hot water cleaned it well. I guess I'll be good for a year. The brush is strong enough to last a while.
