This radiator cleaner brush is designed for effective cleaning of radiators and other hard-to-reach areas. It features natural boar bristles that are soft and scratch-free, making it ideal for cleaning between radiator slats and removing dust and debris. The brush has a long, flexible wire stem that can be bent to fit perfectly into any radiator, reaching even the most difficult spots. Cleaning radiators improves air quality by removing dust particles mixed with warm air, maximizing radiator efficiency, saving energy, and improving hygiene. The brush can also be used for cleaning dryer lint filters, air paths, refrigerator and freezer condenser coils, exhaust vents, AC vents, and other tight crevices under counters and appliances. The brush includes a loop for hanging.
