OVEN CLEANER-4676 can be sprayed or manually applied by brush. A uniform application will insure more consistent performance. The amount of material required, setting time, and the amount of mechanical agitation needed will depend upon the severity of the build-up and the plants' operational constraints. Rinsing of this product can be accomplished using either high or low-pressure water spray. In cases of severe build-up or extended exposure times, high-pressure water rinse will yield better results.
