Product Q&A

Answer:

InVade Bio Drain (Gel) Application Instructions To use Invade Bio Drain: If drain to be treated is not used regularly, first moisten the drain with 1 to 2 gallon of warm water before treatment. Apply product at periods of time during the day when drains are in lowest usage. Apply 4 oz to each drain around the edges, making sure to coat the sides. Repeat daily for 5-7 days and then every 1-2 weeks for ongoing maintenance. For drains that have a very heavy layer of scum, clean the drain with a brush before beginning treatment for immediate results and then maintain with InVade Bio Drain to prevent further build-up.
