I've been thinking of making DIY Windshield washer fluid. I was planning to source some 2-Butoxyethanol and mix it in with a 1% dilution with distilled or demineralised water (whichever I can get my hands on). Do you think that should make a good summer windshield washing fluid or am I missing something? Is there something better than the 2-butoxyethanol I can use? Thanks.
