3 Brushes with angled necks allow easy access to all the hard-to-reach places that can cause cleaning headaches. Corners, crevices, gaps and cracks no longer have to be a problem. Two styles of bristles clean thoroughly and safely. Use stainless steel bristles for hard metals and the nylon bristles to avoid scratches on more sensitive surfaces. All three brushes have wooden handles that make gripping a cinch. Solvent and corrosion-resistant.
