I went to the B&M yesterday and finally found bristle pipe cleaners (they didn't carry them until now), by Savinelli. Man, let me tell you, these are some sturdy pipe cleaners, they resemble wire brushes more than anything else I have seen, and I did use bristle pipe cleaners in the past. I am not sure whether this is a new product by savinelli, or just a new product for the store where I shop. They are fantastic for using on the shank, gets it sufficiently clean using just one cleaner with both ends, that I just have to use a fluffy one afterwards for soaking the remainder moisture. In the past I used Peterson bristle cleaners, and a generic brand for the fluffier ones, or just fluffies whenever I couldn't get bristle. I am quite a happy camper .. as my pipes are just as clean now, using less resources.
