人は何故、エックスという言葉に弱いのだろう。 "X" ね? あなたもきっとそうだと思う。 Xって、だって何か 水滴をシャットアウトしそうじゃない? レインWとかレインZだったら 買ってないでしょ。

ガラス撥水剤はレインエックスが一番ですね。このウォッシャー液添加剤は通常のウォッシャー液に混ぜても大丈夫です。よく点検で青いウォッシャー液を補充されてガッカリなんて事がありますよね。これは大丈夫なんです!

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.

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