This product does not mix with water, allowing it to float on the surface of wastewater contained in the lift station. It will rise and fall with the level of wastewater to keep walls, pumps, hoses, etc. clean and functioning properly. The special soybean oil derivative does not evaporate as quickly as other solvents, so it remains on the surface of the wastewater longer to penetrate and dissolve wastewater deposits. Sold in 5-gallon buckets.
