Claridge offers numerous color options of Guilford fabrics which can be cleaned with these simple procedures. For dust, lint, and other particles that can adhere to the surface you can use a garment brush/roller or a tacky surface such as the back side of cellophane tape to remove them. Spots that become dirty can be cleaned by using a sponge and a mild household detergent such as Woolite.
When it comes to crayons, grease, or ink stains, the tack surface can be spot cleaned with lighter fluid containing naphtha to remove the solvent soluble matter, it sounds a little crazy but this method was even promoted by the housekeeping queen herself Martha Stewart. Any remaining stains can then be removed by shampooing the fabric using a household upholstery cleaner.
One thing to keep in mind is that you should not over saturate the surface with too much water, detergent, or cleaners as doing so may cause damage to the backing under the fabric.
