Washer fluid what does everyone else use

I’ve been using this one for a while. Pretty good results. I always mix with distilled water to prevent any deposits/algae in the tank. I had algae hit a BMW I once owned and I never want that again.

I'm guessing that with most "concentrates" that you add to water, you will have to battle with algae and/or mold growth. That's why typical washer fluids have methanol. In addition to reducing the freezing point, it also prevents growth.

I've been using rain-x (green stuff in summer, orange in winter) for 16k miles with no sensor issues. If problems arise I'll disable the low fluid notification.

Anyone know how to get rid of a stain on the hatch window where the fluid squirts down? Washing seems to be useless. I am wondering if it is permanent damage.

Try Vinegar and Water (1:5). I have same issue but becareful not to get on painted surface.
If it doesn’t work on the first try, try again Daily for a few days. This worked for me.

Or maybe Claybar?

I actually tried a Claybar it made only a slight improvement. I'll try Vinegar/water next time I wash the whole car.
