ACDelco GM Original Equipment 1051515 (01051515) Windshield Washer Solvent

I use this in a bit of an unconventional way. At the end of the warm season, I add whatever is left to the reservoir to make sure any leftover summer mixed fluid has enough anti-freeze capability to withstand the winter. It’s a concentrate, so it’s easy to adjust the strength. Cleans as well as anything else I've ever used. Summer Use: Makes approximately 6.4 gallons of finished fluid. Winter Use (-26°F): Makes approximately 1.1 gallons of total fluid.

Okay, buckle up because I’m about to wax poetic about windshield wiper fluid. I know. But THIS? This isn’t just wiper fluid — it’s luxury in a jug. This mint-scented marvel is the exact same stuff used in brand-new Cadillacs. You know that crisp, fresh, borderline bougie smell when the dealer hands you the keys? Yeah. THAT. Every time I hit the washer spray now, it’s like my 10-year-old Toyota thinks she’s on the showroom floor. ✅ Smells like minty sophistication ✅ Cleans glass like a dream ✅ Subtle flex in the carpool lane Important tip: It must be diluted with water! This isn’t your average off-the-shelf blue juice — it’s the concentrated kind. I mixed it just like the directions told me to and it worked perfectly. If you pour it in straight, it’s probably overkill (and you’ll burn through it too fast). Also, this stuff is weirdly hard to find, so when I saw it on Amazon I basically tackled the “Buy Now” button. If you’re the type who notices the details — like whether your car smells like synthetic pine or the scent of minty excellence — this is absolutely worth it. I told my husband, “Babe, I don’t want flowers anymore. Just keep my reservoir topped off with this.” He thought I was kidding. I was not.

Worked good. I was looking for the scented version. This is not it.

Works well when mixed according to the directions. EZ directions included to follow. Effective at bug and dirt removal; remember to use H2O that is distilled or filtered well as you are effectively building your own high quality windshield washer fluid with a fairly priced AC Delco concentrate solution. One star off for the missing OEM fluid minty-fresh scent that comes in new GM vehicles. Five stars if it goes back in, others agree General Motors, hope you are listening! The not-included scent that folks are clamoring for is helpful in pest remediation and freeze protection which is why it goes into new cars that may sit for months in outside areas before being retailed.

You gotta love that minty smell.

Works great, doesn’t have the minty smell.

Used this for years, expensive but does the job, not watered down like most.

This is one of those products that feels a step above the typical off-the-shelf washer fluid. It’s a concentrate, so instead of just pouring it in, you mix it to get the level of cleaning power and freeze protection you want. What stood out to me is how well it cleans. It cuts through road grime, bugs, and buildup without leaving streaks, and the windshield looks noticeably clearer after using it. It’s also designed as an all-season solution, so you can adjust the mix depending on the weather. Because it’s concentrated, a single bottle goes a long way. You can dilute it to make multiple gallons of washer fluid, which makes it more cost-effective over time compared to buying pre-mixed jugs. That said, the key is mixing it correctly. If you don’t get the ratio right, especially in colder climates, you can run into issues with freezing or reduced performance. Pros: – Cleans windshield effectively with no streaking – Concentrated, one bottle makes multiple gallons – Adjustable for different seasons and conditions – Feels like a higher-quality, OEM-style product Cons: – Requires mixing, not as convenient as ready-to-use – Needs correct ratio for cold weather performance – Slightly more effort compared to grab-and-pour options Overall, this is a great option if you want better performance than standard washer fluid and don’t mind the extra step of mixing. It’s especially useful if you like having control over how strong your solution is depending on the season.
