Best Windshield Washer Fluid 2019 – Buyer’s Guide

Introduction – Best Windshield Washer Fluid 2019

The importance of Windshield Washer Fluid is highly dependent upon the driver.  Some folks use it constantly while others almost never use it.  While you may be the type who is not a heavy user, it is always good to have a full tank of good quality Windshield Washer fluid just in case you have an emergency need.

Imagine driving behind a big truck and all of the sudden they hit a puddle and your windshield is covered in mud.  This may be too much for just your windshield wipers to handle.  A good quality washer fluid will help your wipers cut through the mud restoring visibility before a potential accident were to happen.

Choosing the best Windshield Washer Fluid 2019

There are a few different considerations that one must make when picking the best windshield washer fluid.  Many of the items on our list are just washer fluid additives that boost the power of whatever fluid you typically put in your windshield washer reservoir.  We prefer to put distilled water in ours and then our favorite additive as a booster.  Some drivers in colder areas of the world may need to consider an anti-freeze option to prevent the washer fluid from freezing over.  Adding 90% Rubbing Alcohol to distilled water can help lower the freezing point.

Goal consideration is also important.  Options like the Rain-X washer fluid are more designed as a preventative measure that helps prevent dirt, grime, and water from sticking to your windshield.  The other options are more designed to provide extra cleaning power that helps get rid of the dirt and grime that is already stuck.  These options actually work quite well together if you don’t mind purchasing more than one additive.  The cleaning power of the 303 Tablets combined with the preventative power of the Rain-X makes a great combo for keeping you safe on the road.

5. Camco Windshield Wash

This is meant to be a full replacement for your windshield washer fluid and comes premixed (not concentrated).  No additional water or additives are necessary.  The price is a good bit higher than the other products on this list because it comes as a pack of 6 1-gallon jugs, each of which will equal a tank of washer fluid.

This product does not contain any sort of anti-freeze solution.  It also wouldn’t be considered the strongest cleaner on the list.  Think of it more as a preventative measure than a reactive measure.  It will help keep your windshield cleaner versus cleaning it once its dirty.
