Rain-X ITW-RX11806D Windshield Washer Fluid Additive 500 ml

Recommend

Great product using for last three years.

This product leaves a horrible spray residue that is very hard to remove. I followed the recommended ratio and today it rained slightly but enough to use the wipers. Oh boy, was I in for a surprise. It took an hour of elbow grease to remove all the overspray from my car body. Car shampoo alone won’t remove it (it’s water repellant after all). The only way was hard pressure and lots of micro fiber toweling to get rid of the incredible gunk that matched the V spray pattern of the windshield washer. I hope my PPF is not permanently ruined by the chemical residue. I can see indentations from the same residue spots that I removed. Avoid this product! I would return this junk of a bottle if I could.

It work perfectly in rain,

Used together (Rain-X + SONAX Clear View 1:100), my 2023 Model Y’s windshield went from dusty/filmy to crystal clear after one wipe—exactly what the pics show (before / mix / after). Beads water nicely, cuts road film, and played fine with the OEM wipers. Pros Instant clarity; no smearing Strong water beading for rain driving Cost-effective: small amounts treat a lot of fluid Tesla Y compatible (no chatter from my blades) Cons Add too much and you can get light residue—measure your mix My mix (works great): SONAX Clear View: 1:100 (≈25 ml per 2.5 L / ~0.85 fl oz per 2.6 qt) Rain-X Additive: ~4–4.5 fl oz per gallon of water (the 16.9 oz bottle treats ~4 gal) Tips Start conservatively on Rain-X; you can add more if needed. Top up with distilled water when possible. If switching from another fluid, run a few sprays to purge the old mix. Bottom line: this combo is an easy, inexpensive one-wipe to crystal-clear upgrade.

Nice product. Recommended

Excellent, rain just bleeds of the screen. Works in conjunction with rainx screen cleaner very effectively. Will always use going forward.
