Whether you use an oil or cream to clean your straps, proper application of the product makes for the best result: take the time to get organized, buy the right products to do so, and avoid DIY solutions.
Lay a clean towel on the surface of the table and place the strap on it, after having removed it from the watch. Next, prepare several soft cotton rags that you will use for the different steps of cleaning and polishing. Wet one of these in warm water, wring it out well, so it is just a little damp, and wipe it over the outer surface of the strap. For the inner one, on the other hand, dab by pressing without rubbing too hard.
When finished, dry the wristband well with a dry cloth. At this point, apply the product you are using in circular motions to the surface of the strap. Once finished, let it work deeply for ten to fifteen minutes, and afterward, polish it with a clean cloth, especially the outer part, and let the strap lie flat in the shade and absorb the product well.
"Exotic" leathers such as crocodile, lizard, ostrich, and the like need more care: they often show whitish stains originating from moisture, which stagnates due to the use of products that are too oily. To protect these more delicate and precious skins, use lighter, gentler creams and products better suited to these types of skins.
