Speedy brightener is the fast way to brighten rubber surfaces such as tires, rubber bumpers, door seals and even aircraft deicer boots. It also is excellent for vinyl interiors, padded dash, simulated leather and real leather. Its silicone component will protect the surface from drying and cracking. Speedy is fast because, on most surfaces, no rubbing is required. Just spray it on, let it dry. Drips and runs disappear as solvent dries. Remove from glass, especially windshields, with glass cleaner to prevent smearing. Rinse floors with soapy water to remove build up of silicone which can be slippery and cause injury.
