Slide 2 EVAPO-RUST INNOVATIVE TECHNOLOGY WINNER - R&Ds TOP 100 INVENTIONS AWARD WINNER - CleanTechs Outstanding Technology in Industrial Cleaning NO LABOR * NO ACIDS/CAUSTICS * SAFE ON SKIN! UNIQUE - Works by Selective Chelation at pH 6 - 7 (neutral) REPLACES Acids, Caustics, Electrolysis, Even Media Blasting NO Health or Environmental Hazards FEATURE of dozens of articles in trade publications spanning the Automotive, Marine, RV, and Manufacturing Industries. Slide 3 HOW TO USE EVAPO-RUST 4-PREPARATION (suggestions for best results): CLEAN & RINSE THE ITEM PRIOR TO DE-RUSTING: (Item should be free of mud, dirt, loose rust, oil, and grease.) WHY? 1.) EVAPO-RUST DOES CONTAIN A SURFACTANT TO HELP IT OVERCOME DIRT, OIL, AND SOME GREASES. HOWEVER, EVAPO-RUST IS A RUST REMOVER, NOT A CLEANER AND THE PERFORMANCE MAY BE AFFECTED, ESPECIALLY FROM GREASES. 2.) EVAPO-RUST IS SEWERABLE AS SUPPLIED. ADDING OILS AND GREASES MAY CHANGE THE STATUS OF THE DISPOSAL. IF YOU ARE ONLY DE- RUSTING CLEAN STEEL, ALL THAT REMAINS IS CHELATED IRON AND WATER. IN MOST CASES, ONLY THE IRON CONTENT SHOULD DICTATE THE DISPOSAL REQUIREMENTS. (check local restrictions and dispose of according to local, state, and federal guidelines. 3) RINSING ASSURES YOU WILL NOT BE DRAGGING OTHER CLEANERS INTO THE EVAPO-RUST SOLUTION. RAISING THE pH OF EVAPO-RUST WITH OTHER CHEMICALS CAN RENDER THE SOLUTION USELESS. Slide 4 HOW TO USE EVAPO-RUST COMPLETELY IMMERSE ITEM EVAPO-RUST is easy to use. Fully immerse the rusted item in EVAPO-RUST and check progress in about 30 minutes; no scrubbing necessary. Soak times will vary from 30 minutes to 24 hours depending on severity of rust, type of steel, and temperature. EVAPO-RUST is water based, therefore the active molecules will slow down as temperature decreases and increase as temperature increases. We recommend utilizing EVAPO-RUST at a bath temperature above 60 F. Once rust is removed, rinse item with water. You can now paint, plate, or apply a long term Corrosion Preventative Compound (CPC) such as Carwell CP90. For short term rust inhibition, simply dip the item in EVAPO-RUST and allow to dry. Rinse with water before painting, plating or applying a CPC.

This is a process in which a large synthetic molecule forms a bond with metals and holds them in solution. Most chelating agents bind many different metals. The active ingredient in EVAPO-RUST bonds to iron exclusively. It can remove iron from iron oxide, but is too weak to remove iron from steel because the iron is held much more strongly.
