How often should I use WATER WETTER products it does not say anything about usage on the bottle or on the website.

 

What do you mean by "how often should I use"? You pour half a bottle or so in everytime you change your coolant.

 

thanks for the info. brice

 

No problem, I was just trying to figure out what you meant. I think you are suppose to change the coolant every 2 years, so I would use half a bottle now, and the other half when you change the coolant. I can't see where Water Wetter would hurt anything.

 

Every two years at LEAST. I recommend changing it every year.
WaterWetter is not terribly effective if you are using 50/50.
If you live in a place that has cold weather, you are not going to see a benefit from it because of that.
I live in the desert, so I have only 10% antifreeze. WaterWetter works best in straight water.

It is mainly glycerin (a detergent) and acts as a surfactant.
