303 (230395-100PK) Instant Windshield Washer, 25 Tablet (Pack of 100)

Coming back nearly 10 years later to buy a new pack. I stopped by a gas station to grab a jug bc I ran out, and they were asking $8 🥴 promptly put it right back on the shelf and set a reminder to order more lmao Works great, and anyone complaining about streaks either had something already baked onto their windshield, or used hard water instead of RO/distilled/filtered. Or they're confusing the offgassing of their dash with haze on the outside. Does take awhile to dissolve, so I recommend putting HOT water in a gallon jug, shaking it a bit with the cap on, and then cracking open the cap slightly to relieve the pressure. The fluid gets hotter in your car while it's running and/or in the hot sun, so hot water won't cause any issues. Takes about ~15-20 mins to dissolve and gets all the gunk off my windshield.

I got this windshield washer additive because I needed a clean windshield in all types of weather. It gets quite cold here in the winter(routinely -20C or -4F, and sometimes down to -40C/F). I switch between summertime washer fluid and winter washer fluid and no matter which washer fluid I try they don't keep the windshield clean and free of bugs or greasy road film. I was tired of dealing with the greasy film on the window all the time and now I don't have to. I added one tablet to each 4 liter/1 gallon jug and I noticed an immediate change as soon as I put this product in my car. My windshield is now clean. I chose this product over the liquid ones as it is easy and cheap to ship and easy to store in the car. I did notice however that the tablets don't dissolve quickly if the fluid is really cold, so I had to warm up a cup in the microwave a little. Once the liquid was a little bit warm the tablets fizzed and dissolved in a couple minutes.

This is one of the best purchases I've made of 2023. Our Toyota Sienna's windshield wiper fluid was out for a week or so and after ignoring it for some time the master warning light (a triangle with an exclamation mark in it!!!) lit up. I had no clue if it was related or there was a more serious issue. Being the cheap and lazy person I am, I didn't want to haul myself to Target, Walmart, AutoZone, etc. and overpay for what is basically water ... so I checked Amazon for the concentrated stuff. I trust the 303 brand for car detailing products (and similarly hold a distrust for off brands with multiple consonants in a row - I like my car paint like it is and I imagine the off brand stuff would strip the clear coat), so a 30 pack made by 303 was an instant buy for me. The tablet dissolved slowly in about 10 minutes with tap water in a spare 1-gallon jug that I had around. It ultimately looked just like the blue stuff that used to be a dollar at a B&M store (but now is closer to $4, thanks to inflation). Once poured into the Toyota Sienna's windshield wiper fluid reservoir, the scary dashboard lights all disappeared. The other 29 tablets went on the shelf and will last me the next decade. This is a great product. I would highly recommend!

Good cleaning action but does not lower the freeze point of water. Only for summer use!

Clean very well! Unfortunately the soapy water spots are pretty bad, I try to use when going fast to avoid this..

The best for windshields with distilled water

Pros: These are convenient, cheap, and clean the windshield better than almost anything else I've used. I don't even pre-mix them, I just fill the reservoir with water and drop in a tablet. Cons: If you live somewhere with freezing temperatures, you'll have to add methanol to keep the mixture from freezing, and that will eliminate most of the cost savings. Also, like many washer fluids, this will leave spots on painted surfaces, especially if you mix it strong.

I love 303 products especially that dust repellant you wipe in the interior. I really think 303 should stick to anything but glass cleaner and washer fluid because this stuff leaves a film on the windshield and is so streaky that it doesn’t even break down any grime on the windshield. It makes more of a mess. Only thing to remove The film it leaves is rainx xtreme clean. It makes night driving dangerous because the very hazy film on the window after the wipers wipe. Reason I’m giving it 3 stars is because it’s cheap and if you mix it with some Zep glass cleaner concentrate it doesn’t leave streaks anymore and functions like a very high quality washer fluid. Disappointed in the base product but will continue to buy because I also put other additives to it to make it great and again, it’s super cheap.

Easy to store in the car and remove dirt and grease very well.

Produit conforme à la description, performant et économique. Je le conseille.

I cannot express how much I love these Windscreen Washer Tablets! They have saved me so much money and hassle. I used to constantly buy expensive pre-mixed washer fluid, which not only added up in cost but also took up space in my garage. These tablets have completely eliminated the need for me to buy pre-mixed fluid. I simply drop one tablet into my washer fluid reservoir, add water, and voila - I have a perfectly effective and budget-friendly washer fluid solution. Not only do these tablets save me money, but they also clean my windshield exceptionally well. I've noticed that they leave my windshield streak-free and crystal clear, even after driving through bug-infested areas. Another great thing about these tablets is their convenience. They come in a compact package that takes up hardly any space, making them perfect for storing in my glove compartment or trunk. Overall, I can't recommend Windscreen Washer Tablets enough. They are a game-changer in terms of cost savings and effectiveness. Five stars!

Seems to work but it does take quite awhile to dissolve. If you put it in a jug be aware to really shake it. Best to put in well ahead of use. Not sure if you drop tablet in reservoir how long it takes. Maybe with heat of engine it’s quicker.

Pleasantly surprised to see how efficient this was, ADDED TO EXISTING supposed ‘bug’ windshield washer fluid. Alone, the bug washer fluid was fair at best, adding the tablet to it MADE A NOTICEABLE DIFFERENCE! Well worth the investment in the summertime when bugs are at their worst!
