Water is one of the most damaging substances for fine leather and leather furniture often suffers accidental damage such as ring marks from damp glasses and splashes from spilt drinks. Moisture damage causes the colour to fade and may leave a moisture stain. Water damage also weakens leather: it dissolves its natural oils and they rise to the surface and evaporate, leaving the leather dry and cracked.
How to Treat Wet Leather
Clear up water spills immediately, before they have a chance to soak in. Dry your leather furniture away from sunlight and direct sources of heat: leather should be allowed to dry as slowly as possible. Avoid using the furniture before it is completely dry as sitting on damp leather will cause it to stretch even further.
While the leather is still damp, clean it with a soft cloth dipped into diluted leather wash concentrate, using gentle circular movements and then rub in some leather fixative. As the leather slowly dries, water evaporates and capillary action draws the oils of the conditioner down into the leather to replace them. Before attempting any leather restoration, always test the products in an inconspicuous place, such as on the back or underneath the furniture.
How to Remove Water Stains from Leather
If your leather sofa acquires a water stain, you should treat it with a leather fixative. Wipe it across the surface, using a soft cloth, until the fixative darkens and soaks into the surface; dry the leather immediately with cold air from a hair dryer. The following day, apply some aniline cream for new leather or a leather preserver specifically for restoring old leather and your furniture should look almost as good as new.
