Checkmate chemical drain cleaner is a revolutionary modern and safe solution with dealing with grease and odour problems.  It is highly effective at removing build-ups of grease even when diluted with up to 20:1 parts water.  At dilutions of 50:1 it will immediately kill obnoxious smells at source.  This formulation is a unique triple blend of castor, sugar and coconut oil derivatives which produces a highly biodegradable, versatile product.  It is the unusual shape and size of the molecules in Checkmate and the natural anti-bacterial and fungal disinfection action which can attract and neutralise many types of objectionable smells, especially when dealing with waste, rubbish and effluent.
