Product Description HT-439 is a viscous liquid which has been formulated specifically for cleaning and brightening aluminum or stainless steel air conditioning coils. |
How To Use Product Apply the product by brush or spray. If spray equipment is used it should be constructed of stainless steel or polyethylene. After applying an even coating from top to bottom on both sides of the coil, allow 15 to 30 minutes for the product to loosen the soil. On very dirty surfaces two or more applications may be necessary. In the case of Aluminum which has been coated with oil or turned jet black due to heavy oxidation, pre-cleaning may be required. If such is the case first apply HT-40, allow 15 minutes contact time and then high pressure rinse. Make absolutely sure that all of the HT-40 is removed before applying the HT-439 because the HT-40 will neutralize the action of HT-439. Our experience with HT-439 indicates that when cleaning thick cooling coils high pressure rinsing, (1500 PSI at 4 GPM) is necessary. In other applications, normal garden hose pressure is adequate. Remember to rinse thoroughly to insure maximum cleaning results. This product may also be used on interior or exterior aluminum, stainless steel window frames, bannisters, doors, etc. In this case, the product should be applied by brush and thoroughly rinsed by sponge. Change the rinse water in the bucket frequently to insure adequate cleaning. |
Safety HT-439 is a heavy duty industrial strength cleaner and therefore the use of rubber gloves and safety glasses is mandatory. If the product does contact the skin, flushing with water will remove it. If the product should contact the eyes, again flush with water followed by a mild eye rinse containing Sodium Bicarbonate. |
Ecology This product is completely biodegradable. The effluent, if washed into the soil will break down rapidly. When used on exterior projects and the product is inadvertently sprayed on bushes, trees or plants, it should be rinsed off. Rinsing with water will prevent permanent damage to plants, trees, or bushes. |
Effect On Other Materials HT-439 will not damage most sound paint coatings. If there is any question, a patch test on the painted surfaces should be conducted. As mentioned previously, the product will not damage glass. It will also have no adverse effect on rubber, caulking or mortar. This product will clean certain types of stone, masonry and flooring materials: therefore, if the adjacent area is not going to be cleaned, it should be covered to prevent "clean spots". |
Other Applications There are undoubtedly many other applications for HT-439. The product will remove certain types of rust from steel surfaces. Tile surfaces have been cleaned as well as brass and stainless steel. As other applications develop the information will be made available. Since HYDROCHEMICAL TECHNIQUES, Inc. shall have no control of the use of the product described herein, HYDROCHEMICAL TECHNIQUES, Inc. assumes no liability for loss or damage incurred from the improper use of such product. |
