Windshield washer additives/boosters
These additives are to keep windshield, help in cold temperatures, and refresh glass sealants.
Do they affect your car’s sealant, wax, or coating? I am afraid of using these boosters, some have hints of antifreeze in them, due to the spray getting on car and eating away my Wolfgang.
Thoughts?

Re: Windshield washer additives/boosters
I have been running the P21s additive for about a year now. First time I added too much I think and it was thick and streaky. The second time I cut it in half and it hasn't done that anymore. As for performance upgrade, I haven't noticed. I put silica on my windshield and I think that plays a bigger roll in the good performance of my wipers then the additive does.

Re: Windshield washer additives/boosters
I use the P21s in the winter. I add it to the cheap blue stuff. In the summer I use the concentrate below. Makes 7 gallons of RTU fluid.

Back on subject, read this is another good product for winter fluid. I have not used yet, but would like to try it.

The fluid, that is in each of my vehicles’
windshield washer reservoirs, already
contains the prerequisite additives.
No need to add additional additives.

Honestly I can't tell any difference at all with these "boosters" or additives. Probably better off saving your money for something else that you need.

I put a couple capfulls of ONR in my reservoir.
IME, the cleaning power isn't boosted much, but it does make the water beading better.

Re: Windshield washer additives/boosters
I've recently been using the Rain-X washer fluid additive. It works surprisingly well for an OTC product. The only thing I noticed is after a few months of usage the product was building up on the wiper blades causing them to squeak. After a quick alcohol wipe over the rubber blades everything returned to normal.

I was thinking the same thing. That mckees booster did nothing my windows still froze last winter

Re: Windshield washer additives/boosters
Why would someone use these additives instead of the 0 or -10 (or even -40 in some places) washer fluid you can buy in just about any retail store or gas station this time of year? The stuff is roughly $5 a gallon and doesn't require any mixing.
