FAQs
What is the difference between PT Bio1 and PT-4?
PT Bio1 uses bacteria blends to completely digest and eliminate grease. PT-4 uses solvents to liquefy it and move it out of the system. PT-4 acts faster but does not completely digest the grease, it simply moves the grease out of the system.
What is the best product for cleaning a grease trap?
PT 4 or PT Bio1 are both designed for this application, but PT 4 is fast acting and PT Bio1 is better cleaning.
