Review on 🍊 IBDC032 Invade Bio Drain Gel - 1 qt by Rockwell Labs in Orange Shade by Kevin Mills

SUMMARY: Cleans dirt very well and made a noticeable difference in all drains it was applied to - water sounded like it was flowing down the drain much faster. Not effective against plum flies. Shower cleaned very well. We cleared the debris where the drain flies nested - in the shower door frame - BUT didn't kill the larvae or pupae. Drain fly pupae (looks like little gray worms) crawled through the bio drain unharmed. I had to use bleach and this product together and a hand pressure washer to get the drain flies out of the bottom of the shower door - they were in the metal door frame below. After three uses and 2.5 gallons of bleach and water flushing down the shower screen, the problem was finally resolved.
