Suede leather should not be soaked for cleaning, as this can ruin it; however, spot cleaning suede leather is fine. Cleaning stains on suede is easier if you use a common household product---vinegar---as your cleaning agent. Vinegar should not harm the suede, although you should always do a spot test first just to make sure the suede's dyes will not run or fade.
Brush the suede with a suede brush. If you do not have one on hand, use a dry toothbrush to loosen stains.
Pour 1 cup of white vinegar into a bowl. Dip a cloth in the vinegar. Do a colour-fast test on the suede by rubbing one small, discreet area with the vinegar-soaked cloth. If dye transfers to the cloth, you should not use the vinegar and should consult a professional leather cleaner.
Rub the cloth over soiled areas of the suede. If the whole item is soiled, wet a sponge in the vinegar, squeeze out the excess and rub this over the suede, as advised by Reader's Digest.
Allow the suede to dry fully, then rub it again with a suede brush or, lightly, with a dry toothbrush. This raises the nap.
The suede item may smell like vinegar for a while after cleaning. This will fade.
