PROBLEM TO BE SOLVED: To reduce a low molecular dimethylpolysiloxane remaining in silicone rubber products and causing defective contact, etc., of an electronic circuit by cleaning with 1-bromopropane which is an organic solvent without having flashing property, excellent in safety and showing less effect for the ozone layer depletion or global warming. SOLUTION: This method for cleaning the silicone rubber products for reducing the low molecular dimethylpolysiloxane in the silicone rubber products is provided by comprising a process of an ultrasonic treatment by immersing the silicone rubber products in 1-bromopropane and subjecting with the ultrasonic treatment, and the silicone rubber products treated with the cleaning method is also provided.
