How to Clean the Car Radiator Grid?
2 Answers
Fill the cleaning tank with a 10-15% sodium hydroxide solution and heat it, then immerse the radiator in it for 25-30 minutes, followed by rinsing with hot water. Use a 3-5% hydrochloric acid solution, adding 3-5 grams of hexamethylenetetramine per liter of solution, then heat and clean. After that, rinse with hot alkaline water, and finally, rinse with clean water.
I usually clean the car radiator grille myself because it's crucial for preventing engine overheating. After driving, let the car sit for a while until the engine cools down completely, otherwise it'll be too hot to handle. Then grab a bucket of water or a gentle hose, using low-pressure water flow to slowly rinse the outer side of the grille. Never use a high-pressure washer or scrub hard, as the fins can easily bend or get damaged. If there are insect remains or clumps of dust on the grille, apply some mild car wash soap and gently brush with a soft-bristle brush. I check it monthly, more frequently in summer since high temperatures make the grille prone to clogging, leading to poor heat dissipation. After cleaning, start the engine to check if the temperature gauge reads normal. This saves both hassle and money, avoiding trips to the repair shop. I've maintained this habit since owning my first car, and years of experience prove its effectiveness.
