Saw some of these the other day:

A pack of these tablets costs about as much as 3L of wiper fluid around here, seems like a good deal. Has anyone tried these? The biggest potential problem I see is mineral deposits in the wiper system since it would include tap water.
Edit: Mods, feel free to fix title spelling. I can hit 4 keys with 1 thumb on my phone.
Sure wouldn’t work here. You’d end up with a block of blue ice and a split open washer fluid reservoir. Unless they can make alcohols out of water and some kind of tablet which I doubt.
They work well in non-freezing weather. If you do have to deal with freezing weather you can mix in an anti-freeze but at that point it isn't really worth it over buying it pre-mixed.
I'm looking at these mainly for use in the tropics, so inability to handle freezing temps isn't necessarily a problem. Distilled water (what I usually use in the wiper tank) isn't much cheaper than wiper fluid so I was hoping to get away from that. If this would work well (mainly as in not causing scale buildup) when mixed with tap water then it would really be useful.
I also thought the payment plan was funny...I guess the website offers it for anything with no lower bound on price.
I've used liquid concentrate before. I don't see those doing much to protect against freezing, but I could see this as a way to mix in detergents and the like.
That's how washer fluid was done in the 50s and 60s too.
I wouldn't be too worried about distilled water either; I'm sure the premixed stuff is just tap water too.
