YUP!

Wiper manufactures do not develop their wiper blades with chemical resistant features that are in some wiper fluids. I generally only run distilled water in my wiper revisors but that is primarily because on a few of my cars I run Water injection and share the bottle with the 2 systems. Oh and I also have a a little system that I have a wiper sprayer attached to the underside of my bumper with a separate pump and momentary switch to denture those that like to stop behind me at traffic lights or stop signs with a space of a shoe size.

 

interesting,I’ll try that

 

Occasional wiping the wiper blades with isopropyl alcohol 50 or 75% with a clean rag will prolong the life as well the performance of the wiper blades. Buty I still recommend that blades be replaced at least at the end of winter and before the following winter months after summer. The other BIG item that is really neglected is the condition of the windshield glass. While most will clean them what they don't see is the build up of material that will wear wiper blades and also contribute to the noise a wiper can make at times. This mean actually polishing the glass instead of the normal glass cleaner and wiping.
What works and is very easy to use is a NANO Skin Pad that is design for polishing a car taking the place of traditional clay bars. The investment in one just for glass polishing/cleaning is a bit expensive but well worth the making.
Here is a clone that is reasonably priced?

Not a bad point, we certainly avoid it when we can eh?
Here in VT where 80% of roads are unpaved and most of us live and work on them ( I know Maine is not much different) pretty much everyone runs studs now in the winter and has AWD or 4WD because the way our weather has changed (we are a full climate zone warmer than 10 years ago and the warmth actually makes it worse, it's easier when it stays frozen like it "should") it's gotten weird and ice has become common. I used to run winter rated "all seasons" year round on my Tundra with no issues, but now it's studs in the winter on the CX-5, RAV and Tundra for sure. Most folks here learn to drive successfully on anything short of glare ice. Most folks also learn the hard way when they move here, even studs don't help on true ice.
I have to say the CX-5 is slightly better than the RAV4 in winter for traction, though nothing I've ever driven compares to the Subaru Outback Legacy Wagon we once had!

 

I'm retired, meaning I only drive in the winter now when the weather is good.
But that also means I learned to drive back when we used to get literally tons of snow and now here on the coast it's mostly rain.
We had high horsepower rear wheel drive single or posi-trac vehicles many the size of M1-Abrams tanks.
Most drivers today wouldn't have a clue how to remove them from a 12-foot snowbank.
Before I had my driver's license, I raced in the local ice races on my local lake, which now barely freezes over enough to go fishing on.
The climate is definitely changing ocean temps here keep climbing yearly and the local ski area barely gets in a full month a year.
The annual toboggan Championship may not run again this year because of lack of snow and ice.
10 degrees this morning and 4 on the docket for tomorrow morning but 40's and rain next week and so it goes.
That'll screw up any biological or mechanical device including defrosting windshields.

 

this thread is no longer really generally helpful to all members IMHO except now entertainment purposes.
Lobstah you and me both on the experience of RWD vehicle's in adverse road and driving conditions.
Also I think I have mentioned I Ice Drag Raced in Alaska with spiked slicks. It was simply to add to my experience in the sport but what a mess and scary fricken ride. A 69 Nova with a BB Dyno'd at over 1000HP when it loses traction on the snow all you can do is hold on and see where the "car" takes you. LOL
