PVA SpongePVA sponges absorb more than any other sponge, making for faster and more effective drying. The sponge prevents water spots on all surfaces, and resists mold and mildew. PVA is a high-tech, synthetic material that is lint free and resists mold and mildew better than a regular sponge or towel.Instructions:After taking the sponge out of the container, dampen it and wring out any excess water. Dry sections of the surface until the sponge is saturated; wring it out and repeat. Wring it out before putting it back in the container.
