As a general rule when cleaning Nubuck, Alcantara ®, Ultra suede™, Ecsaine, Micro suede, etc you should only to use products specifically designed for this type of fabric. Avoid using a product designed for cleaning leather. It's also important to do a patch test before cleaning any fabric to make sure the colour or integrity of the fabric won't be damaged.
To do this, apply your cleaning product to an inconspicuous area to see what the effect will be.
Use a napping brush to raise the pile and loosen / separate the fibres. Remove pilling with a single-sided razor blade and then apply a suitable cleaning solution on to an applicator pad and apply to one area at a time (do not over-wet the fabric) and do not use wet steam.
Localized stains can be treated with a d-limonene (citrus) based cleaner (P21S Total Auto Wash) ensure surface is dry before use by leaving window cracked/open or SONAX NTS7 Upholstery Cleaner for BMW, Porsche and Mercedes-Benz Alcantara materials. Avoid alcohol, strong solvents or spirit based cleaners (particularly perchloroethyene and trichlorethylene).
