去除(chu)汽車上的水泥(ni)痕跡(ji)，要(yao)根據水泥(ni)的狀態(tai)選擇合適(shi)方法。

若是水(shui)(shui)(shui)(shui)泥(ni)(ni)(ni)剛沾上且未超(chao) 12 小時，還(huan)比(bi)較軟，此時可先用(yong)(yong)(yong)(yong)水(shui)(shui)(shui)(shui)將(jiang)其打(da)濕浸泡，讓水(shui)(shui)(shui)(shui)泥(ni)(ni)(ni)充分吸收水(shui)(shui)(shui)(shui)分，之后再(zai)使(shi)用(yong)(yong)(yong)(yong)洗(xi)車液(ye)和(he)干凈柔軟的(de)毛(mao)巾輕(qing)輕(qing)擦拭，就(jiu)能輕(qing)松(song)把(ba)水(shui)(shui)(shui)(shui)泥(ni)(ni)(ni)清(qing)除(chu)干凈。而當(dang)水(shui)(shui)(shui)(shui)泥(ni)(ni)(ni)超(chao)過(guo) 12 小時基本硬(ying)化(hua)后，方法就(jiu)有所不同。比(bi)如可以(yi)(yi)使(shi)用(yong)(yong)(yong)(yong)酸(suan)性藥(yao)水(shui)(shui)(shui)(shui)，用(yong)(yong)(yong)(yong)刷(shua)子蘸取適量藥(yao)水(shui)(shui)(shui)(shui)涂(tu)抹在水(shui)(shui)(shui)(shui)泥(ni)(ni)(ni)處(chu)，讓藥(yao)水(shui)(shui)(shui)(shui)與水(shui)(shui)(shui)(shui)泥(ni)(ni)(ni)發生(sheng)反應，之后用(yong)(yong)(yong)(yong)清(qing)水(shui)(shui)(shui)(shui)沖洗(xi)干凈。不過(guo)要注意藥(yao)水(shui)(shui)(shui)(shui)停留時間不宜過(guo)長，以(yi)(yi)免腐蝕漆面。也可以(yi)(yi)嘗試用(yong)(yong)(yong)(yong)汽油，將(jiang)汽油澆(jiao)在水(shui)(shui)(shui)(shui)泥(ni)(ni)(ni)痕跡上，待(dai)其軟化(hua)后用(yong)(yong)(yong)(yong)手輕(qing)輕(qing)扳掉(diao)，操作時要遠離(li)火源、注意通風。另外(wai)，用(yong)(yong)(yong)(yong)電吹(chui)風對著(zhu)水(shui)(shui)(shui)(shui)泥(ni)(ni)(ni)處(chu)加熱，使(shi)其自然脫落；或者(zhe)用(yong)(yong)(yong)(yong)噴(pen)壺將(jiang)白醋噴(pen)在水(shui)(shui)(shui)(shui)泥(ni)(ni)(ni)處(chu)，等(deng)待(dai) 3 到 5 分鐘(zhong)后，使(shi)用(yong)(yong)(yong)(yong)硬(ying)卡片輕(qing)輕(qing)鏟除(chu)，這(zhe)些方法也都可行。

總之(zhi)，面對汽車(che)上的水泥痕跡，只要根據其(qi)狀態選對方(fang)法，并小心(xin)操作(zuo)，就能較好地(di)去除，同時保護好汽車(che)漆面。
