Summary:PROBLEM TO BE SOLVED: To manufacture a silicone rubber product sufficiently reduced in low-molecular siloxanes by efficient cleaning and extraction without excessive expansion of a silicone rubber molding. SOLUTION: The silicone rubber molding is immersed in an organic solvent having an SP (solubility parameter) value of >9.3 but ≤15.0 and a boiling point of 50-90°C and, as a result, low-molecular siloxanes contained in the silicone rubber molding are reduced to manufacture the silicone rubber product.
