Mr.Outback Posted February 17, 2021 Share Posted February 17, 2021 My detailer today told me he uses ONR as a windshield washer additive as he's found the usual methanol/silicon additives in most washer fluids are destructive to wiper blades and also introduce buildup and streaking. He also claimed ONR would act as an antifreezing agent. I live in a winter climate where temps can go down to 0 degrees on some occasions. Windshield fluid protection is critical. Will ONR provide any antifreeze properties to windshield washer water? And if so, what dilution ratio is recommended ? Quote Link to comment Share on other sites More sharing options...
