    FYI when you apply rubbing alcohol to a warm hand with rosin on
    it- it only dries out the water and makes the hand stickier.  This
     was an own goal from the umpiring crew.   The alcohol allows the
    sweat/ water to evaporate, leaving behind a stickier substance,
    like spilling a soda

    用酒精洗手後，帶走了水份只會留下讓手更黏的物質。因此叫 Max Scherzer
    用酒精洗完再來檢查，又說他手黏黏的。當然是裁判搞烏龍。

    often in the wild west days of spf30 and rosin you’d get a gunky
    layer from the mud on the baseball pulling out of the pores and
    sticking to your hand.   so you’d try and clean it off, if you
    used rubbing alcohol it would take off the dirt and some of the
    rosin but get stickier

    在熱爆的西部使用 spf30 防曬和松香後，棒球上的泥巴會和他們混一團黏在手上。
    如果用酒精擦手只會帶走水份而讓手更黏

    the issue is- you are trying to fight sweat which leads to pitches
     slipping, and can go too far.  if you wash your hands with soap,
    you risk a PFAS type film staying behind and that makes your hands
     slippery.   The only way to remove built up rosin residue (esp
    warm/sticky days)-

    但如果怕握不住球而用肥皂清潔，PFAS物質會讓手更滑。
    所以清除那些物質的方法是

    is to put a small amount of rubbing alcohol on a towel and scrape
    it all off.  rosin is white and alcohol is clear.  if you mix
    them, it’s clear on skin.  the reason sunscreen and rosin was so
    good was because it was clear and not brown pine tar.  propellant
    w/ spray spf    tacky

    在毛巾噴一些酒精然後把手刮乾淨。白色松香和無色酒精混合後絕對不像是髒污
    那樣。所以他只是噴了一些防曬油讓手黏黏的而已。
