Citra Float is an all-natural solution for keeping lift station surfaces free of grease accumulations. Made with 100% d’Limonene, this product uses a non-emulsifying formula so it floats on the surface of water. As waste water levels rise and fall, it coats all lift station surfaces and removes heavy grease deposits from lift station walls. It also leaves behind the fresh scent of oranges as it cleans. Biodegradable, so it will not interfere with the biological digestion of existing bacteria. A red indication let you know when to add more.
