Pull apart a 2-inch chunk of steel wool into small pieces. Place the pieces into a recycled food jar.
Add 1/2 cup of white vinegar. Use a craft stick to completely submerge the steel wool pieces. Place the lid on the jar and allow it to soak overnight.
Pour 1/2 cup of boiling water into another recycled food jar. Add a tea bag and allow it to steep for at least 15 minutes. Remove the tea bag and allow the tea to cool.
Paint your raw, untreated wood with the brewed tea mixture. Allow the tea to dry.
Paint over the tea stained wood with the steel wool and vinegar mixture. Within half an hour, your wood will have the appearance of old barnwood.
