Solution Dyed Acrylic Topping Fabric

Although the fabric does not promote mildew growth by itself, mildew may develop on dirt and other foreign substances that are not removed.  This is especially true in warm, humid, dark environments.  A program of keeping the fabric clean through regular washings, BEFORE it gets dirty, will enhance the life and beauty of the acrylic and make successive cleaning easier.
Hand washing in shade or partial shade, not direct sunlight, is best.  DO NOT USE DETERGENT.  Bird and tree droppings, as well as other loose particle soils, should be removed immediately.  Vacuum with a brush attachment and rinse thoroughly with water to remove loose particle soils.  This will also prevent the soils from being re-deposited during the cleaning process.  Once the fabric has been rinsed thoroughly, spray RAGGTOPP™ Cleaner evenly over the entire surface while still wet.  Allow the cleaner to soak for 10 to 20 minutes and then scrub lightly with a soft nylon brush or terry cloth rag.  Rinse thoroughly, preferably until no remaining soap foam is observed.  Additional cleanings may be required.  It is best to determine the need for additional cleanings after the fabric has dried completely.
Once dry, cleaning must be followed by re-water repelling with RAGGTOPP™ Protectant. (This product does not contain CFC's and therefore, is not harmful to the environment.)  Failure to apply will result in rapid re-soiling of the unprotected fabric.
Washing with soap (ie. Ivory or Lux) and warm water is a safe alternative to RAGGTOPP™ Cleaner, but not as effective.
For more stubborn cases, mix a solution of no more than 1/2 cup (4oz.) bleach and 1/4 cup (2oz.) RAGGTOPP™ Cleaner per gallon of water, soak for approximately 20 minutes and scrub lightly as indicated above.  (Excessive soaking with the bleach solution can deteriorate seam threads.)  Rinse thoroughly to prevent streaking on painted and chrome surfaces.  Several cleanings may be necessary.  Once again, RAGGTOPP™ Protectant water repellent must be applied to the fully dried fabric.

RAGGTOPP Protectant was specially developed to protect and maintain fabric convertible tops from harmful elements. The number one factor in deteriorating these treasured, and expensive tops, is acid rain. When you add the damage caused by U.V. rays, smog, tree sap, bird droppings, tar dirt, grease and grit you are fighting a difficult battle against the elements that contribute to the weakening and failure of convertible tops.

RAGGTOPP combats these assaults with ease and determination. The added plus to this product is in how easy it is to apply. No more masking off the paint work and plastic window. This product will not damage either. It just wipes off. As a matter of fact, this product will actually clear up and help prevent water spotting on your plastic windows.

Used monthly, RaggTopp Vinyl Protectant will shield your vinyl convertible top, car bra and exterior vinyl trim from the sun and other harmful elements while enhancing their natural beauty. RaggTopp Vinyl Protectant is not greasy or oily, and leaves a natural-looking, lasting sheen.

While this product was specifically developed for vinyl tops, it shows impressive results on all vinyl surfaces including vinyl seats and vinyl door panels. Not for use on leather, imitation leather, suede or fabric.
