Fiberglass Stain Remover (FSR) from Davis Instruments is a non-abrasive gel designed to safely remove marks and dirt without harming fiberglass. It also cleans stainless steel and gelcoat surfaces and can be used on shower stalls, bathtubs, patio furniture and outdoor grills.
The gel is applied with a brush, sponge or cloth and can be wiped off or rinsed after a few minutes. Davis recommends cleaning a small test spot first.
FSR has a suggested retail price of $29.99 for a 67.8-ounce jar and $10.99 for the 16-ounce size. For information, visit Davisnet.com.
