How to select the glass washer?

When purchasing an antifreeze, pay attention to the fact that the product is delivered in transparent cans with good, high-quality plugs. Such containers will help identifying the fluid defects: it is only necessary to look at the bottom of the can in light. If you see the sediment in the can, it’s not worth purchasing the antifreeze. Pay particular attention to the label; it should be informative, without any strange illustrations. A reliable manufacturer makes responsible for the quality of the label design, readability and application onto the container.

Alcohol is used as the base, with surfactants added. These substances fulfill the main task. One way to test the presence of surfactants and their efficiency is to shake the container before buying. The resulted dense foam occurrence indicates a good quality of the product; otherwise it is better not to buy such fluid.
