Delta shower heads, hand showers and kitchen faucets with Touch-Clean Spray Holes make it easy to wipe away calcium and lime build-up with the touch of a finger. While other faucets may gather unsightly mineral build-up over time, the soft rubber spray holes of touch-clean faucets allow any mineral residue to simply be wiped away for an instantly refreshed look – with no need for soaking or the aid of chemical cleaners.
