Described here is the method of rust, after Dalian Shipyard Turbine workshop, many tests, proved to be entirely easy to use a method. Now introduce as follows: 1 in the corrosion of the surface coated with No. 1 agent, and continue to use a toothbrush scrub until the brush completely brush up. No. 1 Pharmacy (orange) ingredients are: Butanol CH_3 (CH_2) _2CH_2OH ...... 6% ethanol C_2H_5OH ...... 20% phosphoric acid H_3PO_4 ...... 74% 2. With a water edge brush cleaning parts surface of the agent, And wipe the water. 3. Spread 2 parts on the surface of the agent, to be 2 to 3 minutes after washing with water, washed and dried, can be kept up. No. 2 Pharmacy (white) ingredients are: ethanol C_2H_5OH ...... 48% water H_2O ...... 50% ammonia NH_4OH ...... 2%
