To complete the ideal cleaning system we developed the perfect patch. Like Butchs bore shine these patches offer superior performance. They hold more liquid and remove fouling faster than ordinary cotton flannel patches. A special fabric used in laboratories and cleanrooms Triple Twills special weave has hundreds of tiny "ridges and drop zones" which scrub and capture fouling residues far better than other patches. Butchs Triple Twill patches dont shed lint and have been specially treated for maximum absorbency.
