廚房(fang)洗槽處理(li)：小蘇(su)打(da)粉是超好用(yong)的天然除臭(chou)劑(ji)，如果(guo)你常用(yong)小蘇(su)打(da)溶(rong)液當清(qing)潔(jie)劑(ji)清(qing)洗餐具、炊具時，可(ke)以避免洗槽排水(shui)產生臭(chou)味(wei);若排水(shui)管堵塞時，可(ke)將(jiang)一(yi)杯小蘇(su)打(da)粉倒入(ru)，再注入(ru)熱水(shui)，就可(ke)解決！很油(you)(you)的盤(pan)子倒入(ru)一(yi)些(xie)小蘇(su)打(da)，只需用(yong)手蹭幾下，油(you)(you)漬(zi)就去得干(gan)(gan)(gan)干(gan)(gan)(gan)凈凈，小蘇(su)打(da)對聚胺脂餐具還有一(yi)個用(yong)途，用(yong)過一(yi)段時間(jian)的聚胺脂餐具會變(bian)(bian)黃變(bian)(bian)舊，如果(guo)用(yong)小蘇(su)打(da)和百潔(jie)布輕(qing)輕(qing)干(gan)(gan)(gan)擦，就能去掉餐具上沉積的舊色，使盤(pan)子煥然一(yi)新。

小蘇(su)打(da)(da)也可以去黑(hei)頭（1）清潔面部(bu)，（用(yong)熱毛巾敷(fu)臉一(yi)分鐘左(zuo)(zuo)右，毛孔張開好吸(xi)收），（2）準備小蘇(su)打(da)(da)礦泉(quan)水，按(an)照1：10比溶解攪拌均勻，用(yong)棉花浸泡小蘇(su)打(da)(da)水，敷(fu)鼻子20分鐘左(zuo)(zuo)右，拿(na)掉棉花，許多黑(hei)頭已經在鼻頭上浮出來(lai)了(le)。

緩解(jie)腰(yao)痛(tong)(tong)(tong)，如果腰(yao)痛(tong)(tong)(tong)，可(ke)以經常用小蘇(su)打(da)(da)(da)(da)(da)水(shui)(shui)溶(rong)液或者(zhe)膏狀(zhuang)的(de)小蘇(su)打(da)(da)(da)(da)(da)擦洗腰(yao)痛(tong)(tong)(tong)處，這(zhe)樣(yang)(yang)可(ke)以有效地(di)促進新陳代謝，使(shi)疼痛(tong)(tong)(tong)減輕(qing)。首先(xian)可(ke)以把(ba)小蘇(su)打(da)(da)(da)(da)(da)粉末溶(rong)入一盆溫水(shui)(shui)中，用手將(jiang)(jiang)水(shui)(shui)多攪幾遍。使(shi)小蘇(su)打(da)(da)(da)(da)(da)能(neng)夠(gou)很好地(di)溶(rong)解(jie)。然(ran)后用這(zhe)樣(yang)(yang)的(de)小蘇(su)打(da)(da)(da)(da)(da)溶(rong)液反(fan)復地(di)洗腰(yao)部。也可(ke)以將(jiang)(jiang)小蘇(su)打(da)(da)(da)(da)(da)粉末放在(zai)(zai)一個容器里，向容器里加(jia)水(shui)(shui)，把(ba)小蘇(su)打(da)(da)(da)(da)(da)粉末調制成膏狀(zhuang)。然(ran)后將(jiang)(jiang)膏的(de)小蘇(su)打(da)(da)(da)(da)(da)，均勻地(di)涂在(zai)(zai)腰(yao)部，反(fan)復多次。每天這(zhe)樣(yang)(yang)地(di)涂幾次，腰(yao)痛(tong)(tong)(tong)就會減輕(qing)很多。

家具的(de)蠟筆(bi)(bi)污跡去(qu)除，家中如果有正在(zai)(zai)成長中的(de)小朋友，他們的(de)很喜歡用(yong)蠟筆(bi)(bi)到處亂(luan)涂亂(luan)畫(hua)，而造成污跡無法(fa)以水(shui)去(qu)除，用(yong)油漆溶劑雖可(ke)去(qu)除，但此法(fa)會剝去(qu)涂料(liao)而使表面受(shou)損。如果改用(yong)小蘇(su)(su)打則(ze)最為適合(he)，可(ke)將(jiang)(jiang)擰干的(de)濕布(bu)沾些小蘇(su)(su)打用(yong)來擦拭(shi)，即可(ke)絲毫不傷家具，把(ba)蠟筆(bi)(bi)污跡完全去(qu)除。用(yong)小蘇(su)(su)打清(qing)理(li)淋浴噴(pen)頭(tou)(tou)(tou)，用(yong)這種方法(fa)去(qu)除噴(pen)頭(tou)(tou)(tou)上積聚(ju)的(de)礦物(wu)質，讓噴(pen)頭(tou)(tou)(tou)出水(shui)更(geng)順暢。1/2杯小蘇(su)(su)打、1杯醋。將(jiang)(jiang)其在(zai)(zai)一(yi)個結實的(de)塑料(liao)袋(dai)(dai)中混合(he)，然后把(ba)袋(dai)(dai)子(zi)套在(zai)(zai)噴(pen)頭(tou)(tou)(tou)上，用(yong)橡(xiang)皮(pi)筋(jin)扎口，讓噴(pen)頭(tou)(tou)(tou)浸(jin)入溶液。靜置浸(jin)泡1小時(shi)。拿掉塑料(liao)袋(dai)(dai)，調到熱水(shui)讓噴(pen)頭(tou)(tou)(tou)持續噴(pen)數分鐘。

小蘇打(da)(da)雖(sui)然屬于(yu)堿性(xing)(xing)物(wu)質(zhi)，可以溶解(jie)掉(diao)一些油(you)脂，但(dan)作用(yong)僅此(ci)而已(yi)。人的皮膚都(dou)是(shi)中性(xing)(xing)，小蘇打(da)(da)是(shi)堿性(xing)(xing)物(wu)質(zhi)，堿性(xing)(xing)物(wu)質(zhi)能夠(gou)清潔皮膚、去除油(you)脂，但(dan)是(shi)對皮膚有一定(ding)的刺激和傷害作用(yong)。

如果把它直(zhi)接敷在臉上勢必會對皮膚造(zao)成一些(xie)傷害。有的(de)人皮膚非常敏感(gan)，如果沾到了過(guo)酸或者過(guo)堿性的(de)東西之(zhi)后，一刺激皮膚就會出(chu)現(xian)一些(xie)不良反應。

另外，小(xiao)蘇打的健康危害(hai)，碳酸(suan)氫(qing)鈉在常溫下是接近中性(xing)(xing)的極微弱的堿(jian)， 如將其固體或水溶液加熱50℃以上時(shi)，可轉變為碳酸(suan)鈉，對(dui)人具有刺激(ji)性(xing)(xing)和腐蝕性(xing)(xing)，對(dui)眼睛、皮膚(fu)及呼吸道粘(zhan)膜有刺激(ji)性(xing)(xing)，引起炎癥。
