Capella
Journeyman Pro
Occasionally, maybe once a month when I have a bit of time after the round. Or before I go on a golf holiday, in those cases I take the clubs home with me (normally they stay at the club) and take some time with a bucket of warm water and a brush to thoroughly scrub them clean. I am always surprised about the little details that come to light that way ... that the bottom groove is actually white on all my irons for example
