GENERAL CARE & CLEANING:
Periodically inspect tightness of all screws, bolts, and nuts.
Winco furnishings are built to provide durable reliable service when properly cared for. In general all of our products
should be 1) Cleaned 2) Rinsed 3) Allowed to air dry. It is important to note that disinfecting a product is not the
same as cleaning the product. Disinfectants alone will not provide adequate cleaning, they do not have grease or oil
cutting properties to remove grime or hair and skin oils. Over time, the appearance and feel and performance of
your upholstery may diminish if not cleaned properly
CLEANING:
Remove grime, hair and body oils; Your furnishings should be cleaned with mild soap & water solution and a damp
cloth on a regular basis. Avoid harsh detergents or chemicals that could damage the finish of your product. If the
furnishing is disinfected with chemicals or bleach, it MUST be wiped off using only clean water on a damp cloth and
then be allowed to air dry. Failure to rinse with clean water can result in a build-up of residues over time that can
damage your product.
