While it can be difficult to tell whether a scratch is removable, a few general guidelines can be followed. First, it is crucial to assess the depth of the scratch. If the scratch is only superficial, then it is likely that it can be buffed out using a mild abrasive. However, if the scratch penetrates through the finish and into the wood itself, then it is likely that the damage is irreparable.
Examine the type of finish that has been applied to the furniture. Many modern finishes are quite durable and resistant to scratches, but older finishes may be more delicate. As a result, it may be necessary to consult a professional before attempting to remove a scratch from antique furniture.
