Steel Wool Comes in Seven Grades – Each Used for a Different Purpose

Steel Wool and Oak Wood
Oak is a common wood used to build furniture, so if you are working with oak, make sure to use steel wool made of either bronze or stainless steel. The regular and most common type of steel wool used to remove or polish finish contains very low levels of iron which can respond to the chemical compounds that exist in oak, and can cause dark stains to appear on the wood.
