FOAM CLEANER FOR REMOVING CONTAMINANTS FROM THE INNER SURFACES OF HONEYCOMBS OF CAR RADIATOR CORE Russian patent published in 2023 - IPC C11D7/04 F01P11/06 F02B77/04 

FIELD: maintenance of car radiators.

SUBSTANCE: foam cleaner designed to remove contaminants from the inner surfaces of the honeycombs of the car radiator core. The foam cleaner includes an alkali metal hydroxide, a complexing agent, an anionic surfactant, water, and an amino alcohol. The foam cleaner has the following ratio of ingredients: alkali metal hydroxide - 1-5%, amino alcohol - 1-5%, complexing agent - 0.5-3%, anionic surfactant - 1-3%, water - the rest (up to 100%). The complexing agent composition contains at least one complexing agent, and the anionic surfactant composition contains at least one anionic surfactant. The cleaner is made in form of a liquid fed under pressure, which has the ability to form foam upon contact with the material of the inner surfaces of the radiator core honeycombs.

EFFECT: simplifying the production technology, means for cleaning car radiators and providing the possibility of simultaneously cleaning two radiators located one after the other.
