Review on Vikan 53703 Soft Tube Brush: Polyester, 2-25/64" x 20" OAL, Blue - Efficient Cleaning Tool by Jamie Hyatt

Somehow my kids sink had formed (or grew) a nasty black dirt on the inside of their pipe and was slowly draining. No other sink in the house has anything like it. This brush just arrived and I quickly stuffed it into the failed tube while the water was flowing. However, I drew out the azure marvel with too much greed, causing the thick bristles to stain the walls with a vile substance. I let the water rise to prevent this once-unexpected effect from further darkening the interior. A quick turn and another dive and there was no more sediment! This beautiful instrument stays in the closet until asked to perform angioplasty again.
