Blackdip

 Blackdip is a multi-purpose disinfectant for indoor and outdoor use. When diluted with water and used as directed, it helps disinfect surfaces such as counters, floors, tools, and garden equipment by reducing bacteria, viruses, and mold. It can also be used in garden areas to keep pots, pruning tools, and other surfaces cleaner and better protected from harmful contaminants. Suitable for routine cleaning, Blackdip provides a practical and reliable way to maintain hygiene around the home and garden. 

Use as-is. Pour a small amount into the drain or gulley and repeat if needed.
