Or should I stick to the original glass treatment?** A: It will work with anything, if you want deicing, you must use it with a deicing washer fluid as a base, or just put 1/2 a bottle of rubbing alcohol in a gallon of water then add 4 oz RainX... the RainX on it's own does a great job as a cleaning fluid, but will freeze without some kind of additive **Q: Everywhere I look it says don’t add just water to the tank can you or can you not just mix with water?** A: Yes, you can mix it with plain water - it says so right in the description. I suggest using distilled water though, because the minerals in tap water might eventually block up your lines. **Q: Does this leave hard-to-remove stains on car? Clog windshield washer nozzles? Leave a hard-to-remove dirty film in windshield corners?** A: Yes! Has left bad film and water spots similar to hard water spots on the parts of the glass the wipers don't reach. Washed my windshield at the gas station and it did not come off. I am pissed. Probably going to return product and contact rain x for how to clean my windshield. Also leaves a hard water like stain in a line where right side wiper stops in middle of windshield. I do not recommend this product . ## Frequently Bought Together - Rain-X RX11806D Washer Fluid Additive-16.9 fl. oz, 500. ml - Rain-X 800002250 Glass Treatment Trigger, 16 Fl Oz - Exterior Glass Treatment to Dramatically Improve Wet Weather Driving Visibility During All Weather Conditions - Rain-X 5071268 2-in-1 Glass Cleaner and Rain Repellant, 23 oz.
