Machine wash with gentle cycle in cold water or hand wash the product separately. Do not bleach, do not use strong detergents, do not soak for long time and dry it in shade.
Most importantly do not use strong detergents like Ariel matic, henko matic, wheel matic, surf excel matic etc. Because all Matic detergents are very strong, so use normal detergents and the best ones are Tide/Surf/ETA detergents.
