Fix localized wooden parquet floor scratches
This scratches are hardly visible so if you ask me I wouldn't do anything. But I can understand if this is bothering you; if this is the case I'm afraid that there are no hacks to fix this thing (from your question ii have realized that you are asking for a easy solution).Right way to fix it is to sand the floor and then apply lac as finishing layer. According to my knowledge this is the only way to fix this problem.
