Black iron stain removal
A stain remover that easily removes black iron stains attached to wood, eliminating stains in areas where nails have been driven into the deck floor and walls that have turned black.
After installing the wooden deck, if metal processing is done for air conditioning or fence work, metal shavings will scatter and adhere to the wood. Over time, the tannins in the wood react with the metal ions, causing black stains similar to mold to appear on the wood. You may mistakenly think it's mold and panic, but this oxidation-related darkening can be easily removed using "black iron stain remover." What you need to prepare are "black iron stain remover" and a brush or paintbrush. When applied to the stain, the darkening will disappear in 2 to 3 minutes. If fine metal powder remains, stains may reappear, so please rinse with water to wash away the metal powder. It can also be used on the darkened areas where nails have been driven into the board wall. It is not effective against mold.
