Boao 100 Pieces Car Windshield Glass Concentrated Washer Tablets Solid Car Effervescent Tablets Glass Solid Wiper Cleaning Tablets for Car Kitchen Window

Great product

Very easy to dissolve, as others have mentioned definitely dissolve in a bottle before just adding the tablet to the tank. You can make sure it's fully dissolved then and not clog your water tank. Makes the screen nice and clear and has coped with all the grit on the road recently, very well. Leaves windows smear free. So much cheaper than buying screenwash too. Not much of a scent to them but this doesn't bother me too much as the rest of the product is great. Has coped with -3 temperatures without freezing. Highly recommended!

Used them for a while now as I didn't want to keep buying plastic containers. I can keep some tablets in each car, just drop them in and top up with water. They are also working out cheaper at about half the price of supermarkets brand washer fluid.Haven't tested in extreme cold but they didn't freeze at -3 and they seem to wash away road dirt etc.Pleased so far.

So much cheaper than buying screen wash. One tablet in 4 litres and while I’ve only just started using it, it seems better than the supermarket brand I’ve been using. I’ll double up the tablets in winter as recommended by some of the other reviews. But 100 tables for the cost of 3 bottles of ready mix screen wash is great value for money.

Hard to say if they work, water jet nozzle froze in -5 and the screen isn't cleaner than using water , no foam effect ect.

Thes tablets are individually wrapped and will keep for a long time until opened.I have placed 4 x of them in a 1 x gallon container for quick refilling of the window washer bottle in both of my cars.The strenght of the solution is determined by the end user who can add as many tablets as they think they will need depending on the quality of the rain or road dirt that accumulates as winter approaches.Happy that this is a good quality product that will keep your water bottle refilled at a fraction of the cost of pre-bought already made alternatives.

This product is very bad, and I wouldn't recommend buying it.

Quick and easy screen wash. I use 2 in 5ltrs of warm water. Dissolve quickly. Clean the screen well but do not add anti freeze properties.
