Windscreen Washer Fluid Tablets 100PCS Car Screenwash for Cars Glass Concentrated Washer Tablets Solid Car Tablets Glass Solid Wiper Cleaning Tablets for Car Kitchen Window

The tablets come in a small tub, with quite a few broken ones, which isn't a big issue for me as I'll just use the smaller pieces making up the size I need at the time. I tested half a tablet in a 2-litre bottle of water. The tablet fizzes away slowly and takes a fair amount of time to dissolve, even with some good bottle shaking after a while. It resulted in a good coloured mix and foam indicating it had some of the properties one would expect from a windscreen cleaner. This is probably the method I will always use rather than dropping it directly into the car's windscreen washer reservoir.It says they are all-season tablets, but I'm not too sure how well these will work in the winter months in terms of any anti-freezing properties, I'm thinking this will freeze, so unless I take some solution and put it in a freezer to confirm, I am doubtful of the solution not freezing up. That being said, I have used off-the-shelf products that claim to be anti-freeze rated, and that have frozen for me.Overall, I think this is a great solution with huge cost savings given the amount of solution this will make up. I like them!

I rarely give things five stars and laugh at reviews that use cliches like "game changer" However it is rare to try something and think 'why is this not the normal way of doing it.'These are brilliant.They are in a small container suitable for the job and will sit in my garage until needed. I also put two in a freezer bag and stored them in my car tool kit just in case.After emptying my car washers by spraying them a lot. I decided to mix some up in an old container 1 tab to 4 litres. The tablet crumbled easily and dissolved quickly, the smell was OK.from then on it was business as usual. I went for a long planned drive meeting with a lot of bugs along the way, this worked at least as well as normal preprepared washer fluid.Consider the savings to you, consider all that coloured water being transported around the world, consider storing these in your car in case your washers go empty.if you do not want to prepare find out the capacity of your cars washer reservoir.I hope you find my review helpful
