TEAK WONDER® BRIGHTENER is a lightening process used to eliminate shading from the teak which may still persist even after the application of the TEAK WONDER® CLEANER. The application of TEAK WONDER® BRIGHTENER is not always necessary, but when used on aged surfaces it has an effect that seems miraculous: the teak immediately regains its natural colour (like newly sanded but without removing precious layers of grain). The brightening process should be carried out on a wet surface, ideally straight after cleaning. Apply TEAK WONDER® BRIGHTENER sparingly and evenly to avoid a patchy result then wash the deck. The effect of the TEAK WONDER® BRIGHTENER, is immediate and the result instant. As with the cleaner, rinse away the solution with plenty of fresh water.
