<p>Invention pertains to agents for chemical treatment of metal and metal-containing surfaces for the purpose of removing rust and corrosion products, and it may be used in various branches for preparation of surfaces prior to painting, priming or application of protective coatings, and it is defined as agent for cleaning metal and metal-containing surfaces in a form of gel containing rust-preventive and auxiliary components at the following ratio, including: rust-preventing component 250-:-400; water glass 50-:-150; colloid stabilizer 5-:-10; colorant-indicator (methylene blue) 0.02-:-0.1; water 300-:-700. As compared with known rust-preventive agents the proposed cleaning gel features improved adhesion, does not contain toxic components, allows efficient and even cleaning of surfaces of sophisticated configuration and expectant utilization of waste.</p> |
