Windshield Washer Fluid Buying Guide

An often overlooked service part for your car is windshield washer fluids. Not only does it remove dirt, tree sap, bugs and road grime from the windshield but it will also improve your driving with clearer vision.

Many washer are tailored towards certain aspects such as dead bug residue, freezing temperatures and all season usage. Rather than relying on plain water, a dedicated fluid will dissolve stubborn dirt and provide a streak-free clean each and every time.

Freeze Protection

A potential issue with certain windshield washer fluids is that they can freeze in cold weather. However, some manufacturers will offer formulas designed for the winter that won’t freeze and help form a barrier to prevent icing of your windshield.

You may also add methanol to the formula, which will further increase the freezing point of the fluid. For example, the Aqua Charge Ultra recommends that you add 13 gallons of methanol to 55 gallons of the fluid. However, you are only able to do this if the fluid is compatible as it may cause adverse effects.

Types of Cleaners

The three forms a windshield washer fluid is available as include a tablet, concentrate or premixed formula. The most common formula is premixed and it can be simply poured from the bottle and into the tank.

Both the tablet and concentrated formulas will require mixing with plain water before being poured into the tank. For the best results, you will want to follow the instruction upon the bottle. Using too strong of a formula may stain any surround trim near the windshield.


Windshield washing fluid is inexpensive and worth spending a little extra to get the best you can buy. Attempting to use plain water and constantly use your wiper blades can be time consuming, wear out the wipers and even scratch the windshield.

All of our recommendations are suited to a range of budgets and available in multiple types. We highly advise that you choose a formula best suited to the climate for effortless cleaning. If you are subject to cold weather on a regular basis, the addition of methanol may be worth trying out, which ensures the windshield washer fluids you use don’t freeze.
