If scrubbing doesn’t remove all of the rust, then a homemade remedy may be needed. You can make a paste of cream of tartar, borax and hydrogen peroxide. To make the paste, use 1 tsp. of cream of tartar and 1/4 cup of borax. Add just a little hydrogen peroxide until a paste is made. Apply the paste to the evaporator coil. Wait 30 minutes and then wipe off the paste. If rust still remains, repeat the procedure.
