The cleaning of leather and suede is a craft practiced by skilled artisans. We defer to our own specialists who carefully grade and inspect each garment prior to cleaning. Unlike cleaning normal fabrics the cleaning of suede and leather requires extensive work post cleaning to restore the garment to its original condition. For example smooth leathers often require retexturing to achieve the same finish and Suede garments frequently require re-tinting to restore their original colour.
During cleaning the oils within suede and leather garments are removed. Part of the processing involves re-oiling the skin to keep it supple. During re-oiling the skin can become a few shades darker. For this reason you should always clean garments that are part of a set together.
We can only implore you to choose specialist leather cleaner -- we have too many horror stories of what happens when customers entrust their treasured suede and leather garments to dry cleaners that are not familiar with the appropriate methods.
