BIG YELLOW is a heavily built caustic drain opener and is effective on organic matter common in industrial food plants and municipalities.  Big Yellow is water activated and creates considerable agitation, heat and non-flammable gas pressure, releasing aluminum hooks to soften and cut the grease in sewer lines and grease stations.

NOTE:  Big Yellow is considered HazMat by FedEx and a $30.00 HazMat fee is added to each 50 lb. container.  For orders of 6 or more containers, please call to arrange more favorable shipping options.
