About Auto Rain Sensing Wipers.
When applying Rain-X or similar products, the automatic detection of rain on the windscreen will work less effectively.

 

That is from those that do not read the directions on the bottle. Rain-x *works with rain sensing systems if applied correctly.
*Vehicle velocity is a factor.

If members don't use a product properly or for that matter at all then please through fact based information post the source of a claim about a product.

While these days there are equal and perhaps better products now then RAIN-X is still currently the best known and likely the most used for the average consumer and professional race drivers and or riders in the world.

And yes SPIT from your face /mouth is still better then any product on a mask or visor to prevent it fogging up.

And in a pinch from experence..... if you don't have a bottle of Rain-x and caught in the rain with wiper failure you can SPIT on the windshield in a small area directly in front of the line of sight to drive and it will work just like
Rain-x. ROLMAO

 

Bottle labels from the manufacturer are one thing, experience is another. A Google search shows different opinions.
Personally, I experience that Rain-X shows a haze when wiping at low car speed and little rain. This may also affect the rain sensor.
YMMV

 

google search OMFG really dude, you base empirical facts on a googal serch from those much like yourself DIY at best? lol
Next time do a Googal serch for real facts and information as I am about to tell you and other about a HOW_TO get the real information and formulate a conclusion .

And you would be applying it incorrectly LOL Next time read the directions.


As for the manufacture labels ... well sir I take it 1 step further and look into the SDS (Safety Data Sheets) and other sources of required Government reporting on product ingredients even those that are under the category as proprietary. You can actually get the components just not the quantity or % of each if you know where and how to find that information.

So while I do read that on many platform forums people "beetch" about Rain-X not working it all goes back to either not reading the directions or having a severely pitted windshield . or a film that builds up from hard water and not occasionally cleaned and even removed by stronger means to get back to the actual glass and not the deposit build up. LOL

I have also used Rain-x and have been at one time have been an employee of an auto parts store that carried the Rain-x a few years later in my own stores a dealer and retailer for the product starting in about 1979 (but sold it a couple years before then) and the biggest complaint even back then was it left a film or didn't work. When I showed customers how to apply it and that they needed to clean the windshield glass suddenly.... a MIRICLE>>> RAION_X WORKED rolmao.

 

If you want to convince people that you are right, I advise you to approach them with more respect and less arrogance.

 

shocking !!! lol
Dude I don't care if some don't want to take my advise suggestions or information. Nor do I really care what some think about me.
Here is the thing, I have spent a lifetime ( over 50 years) helping people and getting the education, professional training and often certifications to do so. I also keep current on many of my certifications which usually is every 3 years or so and cost several hundred USD $$ and a test to pass. So really when a member post they don't like how I post and take it personal ... well try getting a little thicker skin! cuz I dont giv-a Rats (see picture0 what you or other may think about me and how I respond. it is within the guidelines. maybe edgy but still acceptable.



A thread you personally should look at!
What do you do or have done for a living - Mazda Forum - Mazda Enthusiast Forums

 

I have my information also from the Mazda CX-5 owner's manual August 2022 where it says in the chapter Switches and Controls - Windscreen Wipers and Washer:
"If the windscreen is coated with water repellent, the rain sensor may not be able to sense the amount of rainfall correctly and auto-wiper control may not operate properly".

But I guess that the Mazda engineers do not spent a lifetime (over 50 years) helping people and getting the education, professional training and often certifications. They probably also do not keep current on many of their certifications every 3 years or so and maybe didn't want to pay several hundreds of US$ and doing a test to pass.

 

Dude you need to learn how to READ. Your own information the operative word is :MAY"!!!!!!
That single word has gotten so many people and business out of law suit liabilities and other legal action I couldn't begin to count how often and how many. LOL
BTW I am one of those professionals you mentioned. LOL


The basic definition of the word "MAY"
You use may to indicate that something will possibly happen or betrue in the future, but you cannot be certain.


The most commonly used that we hear y or read daily is weather person stating such phrases like "It "MAY" rain or snow today? That Typhon "MAY" hit the island of Yap?

 

Nitpicking.

Oh man, stop your arrogant useless fights against others on this forum.
It's not about the technical information you provide, it's about the way you communicate and present yourself. Maybe you should take a course on that.

I hope I provided some useful information to the OP.

I rest my case.

 

Dude once again I don't care what you think about my responses methods but look who is name calling? Rarely do I ever directly name call any member unless they post in the fashion of direct name calling like yourself!
I am not thinned skinned and laugh and actually get highly entertained by a few member posting information much like your mostly . COPY AND PASTE from the internet.
Mind you I don't knock it and it is helpful even for me at times when i am trying to help members .

As for your MAZDA owners manual info
Your information was useful but technically a cautionary by the auto manufacture and not absolutely fact based? BTW if you read all the pages from front to back in the language you understand you would read numerous disclaimers in the owners manual as well the word "MAY" and caution. These owners manual are written and checked by first and ASE for technical accuracy, by an editor for correct writing, a law office or attorneys to make sure such thing they may be held liable for are not printed, which goes back to that word "MAY" . LOL
We or at least I know exactly why you posted it . LOL

Dude I have engineered and manufacture automotive products for decades and know all the legal wording that my Marketer uses for my products in advertising and the installation guides to protect my interests.
