Who is SPER Chemical?

     SPER Chemical Corporation has been a Clearwater Florida based water treatment manufacturer since 1980.  We have produced both potable (drinking) municipal and agricultural water treatment blends for control of natural minerals in the water to prevent scale buildup and corrosion within the water distribution systems. You can visit our main water treatment site here:

     In 2013, after a comprehensive investigation researching the most advanced current chemical studies, we began producing a new innovative formulation blend that we call Rust Preventer®. It as been applied to numerous non-potable irrigation systems throughout Florida and various southeast irrigation systems with excellent results, especially when compared to the other products (Rid O Rust®, UnRust®, etc.) that have been on the market for years and years.  Our Rust Preventer has had zero complaints over 10+ years from all of our customers that have used it.  Please review the Product Data information along with our interactive Dosage/Usage Calculator to determine your exact system needs.  We not only produce our Rust Preventer® for rust prevention for your irrigation system, we also have a easy to use Iron Stain Remover for eliminating the current stain you have prior to the installation of our Rust Preventer® treatment system.
