What equipment is needed to produce glass water for automobiles?

It takes about 3L to fill a glass of water. Take 2.5L pure water (tap water is mainly afraid of clogging the nozzle with fine sediment) and buy a bottle of cheap white wine (generally about 500ml, mainly using ethanol), which can effectively remove some dirt similar to shellac on the glass, or use medical alcohol instead. ), and finally add a coke bottle cap cleaner mainly because the cleaner should be selective, otherwise it will corrode the wiper for a long time.
