INDUSTRIAL AND TEXTILE DETERGENTS - ITD DETERGENTS DELIVER! We concentrate all of our products to the maximum limit of solubility. We don’t like to ship water. When we say, concentrate”, the product is to be cut or diluted before it is sold to your customers. Read the instructions carefully before preparing these products. Labels and SDS’s for the ready-to-use (R.T.U.) products are available from our office. We use the phrase “ready to use” to indicate that we have diluted the product to a strength that is most easily sold to your customers. This may be half strength, quarter strength, or less. The choice is yours: “ready to use” for convenience or “concentrate” for economy.
