The tablets dissolved in about a minute and left no sediment. We plunked a few tablets into the glass container here to show the instant washer fluid process. The tablets can be dropped into the washer fluid reservoir or mixed separately. The plastic storage tube easily fits in most glove boxes, and each tablet makes one gallon of washer fluid. It was a little hard to believe when we opened up the shipping box, but 303 Instant Windshield Washer Tablets packed 25 gallons into 25 tablets about the size of four stacked quarters. Running with Rain-X 2-in-1 All Season takes unexpected freeze-ups out of the driving equation.

Even with all the electronic reminders and regular maintenance, it's way too easy to forget there’s still summer washer fluid in the reservoir until it freezes up on the way to Thanksgiving dinner. Hydrophobic treatment helps stop salty winter road spray from sticking to the windshield or headlight glass in the first place.Īll-season convenience is the biggest advantage of the feature-packed formula. Automatic Rain-X window treatment was a bonus. The orange liquid powered through bugs and road grime with streak-free evaporation for a clear view of the road. We blasted a gallon over the windshield and through the headlight washer out on the road with excellent results. The four-season heavy hitter is a bit more expensive than other blends but packs unparalleled formulation and temperature range. With summer bug clearing power, water-beading hydrophobic treatment, and a zero degree temperature rating, Rain-X 2-in-1 All-Season is the one windshield washer fluid to rule them all.
