DocVision windscreen cleaning tablets are 100% biodegradable and without any plastic packaging, there is no waste disposal or recycling requirement- creating further energy savings. Using just a few millilitres, as you would in a four-litre or so washer bottle, it was a screen star, topping the cleaning tests. Along with high-quality windshield wipers, you’ll want to make sure you’re using a proper windshield washer fluid to keep your front windshield clean in between car washes.
You’re stuck with the same concentration all year round, which makes it cheap in winter and relatively expensive in summer.It's a bit on the more expensive side when you compare it to concentrated solutions that you mix yourself, but it's comparable to other one-gallon solutions. I too was getting black slime in the bottle, BUT that was coming from the pre mixed fluid that I was using. The second entry from the Tetrosyl line-up is from one of the oldest names in the sector, and is more conventional than the Demon Shot Booster (left).

It's protected against freezing in temperatures down to -27°F (-32°C) and is a de-icer to help melt ice quickly.One quart of the solution makes 55 gallons of finished washer fluid, making it one of the most cost-effective options available. While Prestone's all-season washer fluid is capable of winter protection, you may live in an area with harsh winter conditions. Second, pay close attention to whether you’re purchasing a pre-mixed solution or a concentrate that needs to be mixed with water. Before doing that I had tried to flush the bottle out with a hose, but due to a 90 degree bend just below the filler, it made it quite difficult. Each tablet can be mixed with four liters of water, so this option gives you a total of 120 liters of windshield washer fluid.
Before siphoning off the Steradent, I blew down the siphon tube to 'mix up' the bottle contents to help siphon off the gunge. The solution is methanol-free, but if you want it to work in the cold, you'll have to add methanol for a freezing point of -20°F (-29°C). Having recently had a bit of trouble with my washers on a 2013 Honda CRV, it was looking like a trip to the garage to get them to strip out the washer bottle, which is housed under the front offside wing. Neat, it claims to be good for -36C, but at the -9C solution we tested it at it lasted 90 minutes in the deep freeze, and was one of the cheaper options.

Whereas recycling plastic containers is a good option, many also find their way into landfills and also some even get dumped into our oceans – which is becoming a major environmental problem around the world. I don't know about the black stuff, what I have seen is a clear coloured or greenish coloured thick slime which is some sort of algae, even if you kill it off its still going to block the pump. While purchasing actual windshield washer fluid is convenient—you just pour it into your reservoir—there is the more cost-effective option of using tablets.
Proper windshield washer fluids will break down dirt, dust, debris, and even bugs on your windshield for a proper wipe. The first is an all-season 3-in-1 solution specially engineered to keep your windshield clean and clear all year long.
