CLEANER # 104
Cleaner # 104 is a non-flammable, non-fuming or hydrochloric type cleaner used for removal of oil, grease, organic coatings and oxides from most metals. Cleaner #104 can be used hot or cold and can be applied by dipping, brushing, swabbing or spraying. It contains inhibitors, which make it safe for cleaning iron and steel and copper base alloys. It is also effective for cleaning and light etching zinc base die castings aluminum and galvanized steel.
Cleaner # 104 has a phosphoric acid content of 50% by weight. This acid strength coupled with an effective blend of emulsifiers, solvents and penetrates make it an ideal single-step cleaner and deoxidizer for most metals. This material will effectively dissolve rust; however, it is not designed to remove heavy black oxide scales from steel. It leaves a light phosphate film on steel and zinc, which is an excellent base for painting.
Immerse parts in the Cleaner # 104 solution for a period of time ranging from a few seconds to several minutes depending upon the degree of contamination. Use a scotch brite pad and apply medium to heavy scrubbing, depending on degree of oxidation. In most cases, the mixtures can be used cold. However, cleaning and oxide removal will be facilitated if the solution is heated to temperatures in the range of 130° to 150° Fahrenheit. After treatment the work should be rinsed in clean running cold water, then in hot water and dried.
For application to large objects such as frames and cabinets the diluted mixture at room temperature is applied by sponge, brush, or cloth, whereby the surface is thoroughly wiped with the cleaning solution. In cases of severely rusted surfaces, several applications may be required. After this, the work should be thoroughly rinsed with water. It is important that the parts not be allowed to stand for more than a few minutes after brush application of the cleaner to a metal surface before rinsing is done. Long standing before rinsing and after application of the cleaner may cause stains like phosphate coatings to form.
