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...
Ron@Optimum Posted February 17, 2021 Share Posted February 17, 2021 Your detailer is correct that ONR is an excellent windshield fluid additive, but wrong in suggesting it's an anti-freezing agent. I add a cap full of ONR to my reservoir (there is no "suggested ratio") and then fill with traditional washer fluid. I don't know about washer fluids destroying wiper blades (seems counter intuitive to me) but I believe ONR will reduce smearing/streaking.

Lowejackson Posted February 18, 2021 Share Posted February 18, 2021 I will echo Ron's view, use a dedicated windscreen wash and use ONR as a booster. No idea if washer fluids will damage wiper blades but suspect even if they do, UV and abrasion will have a far bigger impact. When things get warmer, would suggest getting a glass coating. Clear glass is such a critical safety feature and a good coating can make a big difference. Quote Link to comment Share on other sites More sharing options...
Detail Mutant Posted February 18, 2021 Share Posted February 18, 2021 Based upon my experience using a rinseless/waterless wash from another company(Ultima) than contains silicon, it significantly increased wiper chatter which increases abrasion on the wiper blades. Seems counter-intuitive as to what silicon is marketed for but this is what I observed. Made sure to never use that product again especially on the windshield.

Mr.Outback Posted February 18, 2021 Author Share Posted February 18, 2021 The "chattering" from silicon windshield fluid additives is, I suspect, due to a somewhat obscure engineering fact : for bearings, similar materials guarantee friction and galling due to molecular attraction, while dissimilar materials (one hard, one soft) have less attraction/ friction. Alcohol in any form may be hard on wipers but unfortunately seems the only additive fluid makers use to prevent fluid freezup (fyi I usually use small amount of propylene glycol deicier to clean wiper blades (Prestone makes one such product)).

First by car's dealer with Crystal Fusion 2-parter which quickly stopped working and turned glass to sandpaper, and second by my local Opti-Coat detailer who applied Glassparency 2-parter which has been working much better. ONR's now in washer fluid. Quote Link to comment Share on other sites More sharing options...
Bullet Posted May 19, 2021 Share Posted May 19, 2021 ONR as windshield washer. At what concentration?. Quote Link to comment Share on other sites More sharing options...
Ron@Optimum Posted May 19, 2021 Share Posted May 19, 2021 there is no recommended ratio - I just add a capful Quote Link to comment Share on other sites More sharing options...
