It sounds obvious, but cleaning the strap regularly will help to keep your strap in optimum condition. Sweat and dirt will eventually cause the strap to deteriorate, so a regular wipe with a clean, dry (or slightly damp) cotton cloth is recommended. If you intend to buy a specialised cleaning product you would be advised to avoid any that will strip the natural oils from the leather. Also, a leather cleaner should not leave an oily residue (which can make the strap susceptible to bacteria and can break down the stitching). A leather conditioner is something that should be used only occasionally. Conditioners contain fats and oils to help replenish the leather, but I avoid any containing petroleum or mineral oils as these ingredients will damage the leather in the longer term. It is always a good idea to test the cleaner / conditioner on a small area at the back of the strap first – many products can change the colour of the leather. One more point to mention – please remember that leather is a natural material and should never be stored in plastic (because it encourages the growth of mildew and bacteria and can damage the leather).
