Oxcon (Oxalix Acid Concentrate)
Oxcon (oxalic acid concentrate) is the only effective treatment for rust stains from around nails, spikes, and screws.
Oxcon comes as a concentrate that is diluted with water prior to use. It is best applied using a garden type pump-up sprayer but a brush or broom will also work. Apply a liberal amount to the wood, let it work on the surface for 10 to 15 minutes and rinse it thoroughly with clean water.
**This product cannot freeze. If you need this one in the winter, give us a call and we can help coordinate heated shipping for you. Â
Oxcon should not be used for spot cleaning since it may cause blotching of the surface.
