I love the how well the standalone gallon rain-x jugs work.will adding this to non-rain-x fluid make it work just as well as standalone? or not quite?

be cautious i had a washer fluid i added this to and 24 hours later the near as i could tell the rainx reacted with the blue dye in the washer fluid and i had clear washer fluid with a layer of blue sticky slime floating on top of it i have only had it happen once but might mix this in a jug with you preferred brand of washer fluid and let it set for a day before you add it to your vehicle reservoir to make sure it wont react the same way

Does this product work well with de-icer washer fluid? Or should I stick to the original glass treatment?

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

Everywhere I look it says don’t add just water to the tank can you or can you not just mix with water?

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.

Does this leave hard-to-remove stains on car? Clog windshield washer nozzles? Leave a hard-to-remove dirty film in windshield corners?

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 .

とても良い商品で、お勧めです。

私は、まず、500mlのペットボトルにウオッシャー液を約490ml入れて、この液を僅か5から10ml入れると、ウオッシャー液の濃度に関わらずかなりの撥水機能を発揮します。又、ワイパーの汚れを取りながら塗り込むと、ガラスとの摩擦が無くなるのか、ガタガタが無くなり、僅かな雨の時でもスムーズに撥水してくれます。お勧めです。

タンクに注入するだけで簡単です

従来あるウィンドウワッシャー液に混ぜるだけなので無駄なく使えます（タンクの中のワッシャー液が無駄になりません）

控えめな弾きです

ガラコ等のようにがっつり弾くことを期待しているとそこまでではないですが、明らかに何もしないよりかは弾きは良いです。がっつりと弾かない反面、油膜が酷くなることも少ない（遅い）ように感じます。希釈して使える点が良いのでリピート購入しています。
