Thomas writes,

Do borate treatments leave a visible residue?


It depends.  We have two main borate treatments.  One is Timbor, which is a powder that you mix with water.  Timbor will leave a white residue because it is a powder.  The best wood treatment borate product on the market is Bora-Care which is made by the same company that makes Timbor.  Bora-Care is the preferred choice because it not only penetrates deeper into the wood and lasts longer, for the life of the wood, but it also dries clear so you can easily paint, stain, or seal whatever it is you are treating.
