Cleaning rinse preparation designed to remove greasy impurities from the surface of the engine, engine compartment and the bottom of the vehicle. It also cleans the plastic parts of the engine. The sprayer is supplemented with a tube that ensures precise application of the product even in hard-to-reach places. ARVA® creates a strong active emulsion that binds impurities and washes them away. ARVA® is rinsed with water. Instructions for use: Shake the spray thoroughly before use. Spray the product evenly on the individual parts and leave it on for 5-10 minutes. Then rinse with more water. Leave the product on for longer on thicker layers of impurities. The product can also be applied upside down if necessary. When applying to hard-to-reach places, attach the tube to the spray adapter.
