ซิกเนเจอร์ซีรีส์ น้ำยาทำความสะอาดกระจก สเปรย์ปราศจากแอมโมเนีย

Used it on the windshield after a long highway trip, and the bug splatter came off with almost no scrubbing. The ammonia-free formula is a big plus, since I didn’t get that headache I usually do with other cleaners, and the streak-free finish lasted for days.

The sprayer gives a fine, even mist that covers the windshield quickly, and I didn't have to scrub at all to get rid of the bug splatter from the highway. Glass came out crystal clear with no hazy residue left behind, even in direct sunlight.

The ammonia-free formula is a huge plus since I can clean all my car windows without the headache that other sprays give me. Left the windshield looking perfectly clear with no streaks even in direct sunlight.
