It’s so hard to believe that your iron table is rusty. You don’t have to place it in your warehouse, you still can reverse the condition.
By using penetrant grease and lube liquid, your iron table condition will be restored. First, spray or apply the penetrant grease and the lube liquid on to the table’s surface. Wait after 10 minutes for the liquids to work. After that, you can scratch the surface by using sand paper. Repeat the scratch action using sand paper for three times. Then you can see that the rust on your table iron has gone.
