Rummaging through some (very) old tennis stuff, I came across a tag that must have come with a racquet I bought. Here's what it said, hope you find it interesting... <quote> The Fairway grip is the best in the world. It is produced from the finest calf skin obtainable and will retain its tackiness indefinitely, provided you look after it. You will find after considerable use your grip appears to be losing its “tack.” This is only because it needs cleaning and the best way of doing this is to saturate a cloth in methylated spirits (denatured wood alcohol) and rub it over the grip (this will remove all the dirt which has collected on the surface). Allow about half an hour for the spirit to evaporate from the leather, then apply a small quantity of castor oil. Allow eight hours for the oil to penetrate into the leather and your grip will be ready for use and will again feel as good as new. Do not apply too much castor oil as this will result in making the grip greasy. We strongly advise you to ask your Professional to carry out the treatment recommended by us in this folder. E. B. BALMFORTH LTD 2/4 MEANWOOD ROAD LEEDS LS7 2AD <unquote> Has anyone tried this with their leather grips? Did it work well? And would TW recommend this kind of care for its Private Label leather grips? ---------- Added on 9-15-2007: I tried Denatured Alcohol from Ace Hardware today and it removed some of the color of the leather grip. So be warned. Will report back on using mineral spirits instead, mentioned by sigep1967 in post #2 below.
