Lub vaj hnub ci yog khoom siv uas hloov hluav taws xob los ntawm lub hnub rau hauv hluav taws xob. Cov khoom siv hnub ci tau yuav hauv cov khw muag khoom yuav tsum tau ntxuav tshwj xeeb thiab muaj nyiaj ntau.

Cov Lus Qhia
Kauj ruam 1
Txiav ib daim ntawm cov tooj liab kom nws yog hais txog qhov loj ntawm lub qhov cub hluav taws xob. Ntxuav koj ob txhais tes kom tsis txhob muaj cov stains greasy ntawm daim ntaub. Ntxuav cov ntawv tooj liab nrog xab npum kom tshem tawm ntau yam stains los ntawm nws. Siv cov txhuam txhuam los yog ntom ntawv txhuam kom tshem tawm cov tooj liab oxide txheej. Muab cov ntawv tooj huv si tso rau ntawm lub rooj kub kub thiab tig rov los ntawm kev sib tsoo.

Raws li tus tooj liab pib ua kom sov, koj yuav pom cov xim liab-xim txiv kab ntxwv rau ntawm qhov chaw. Thaum nws kub dua, cov pob hauv yuav dub. Txhua lub xim yuav ploj thaum lub kauv hloov xim liab. Thiab thaum lub qhov cub pib ci, ib daim ntawv ntawm tooj liab yuav tau them nrog tooj liab dub oxide. Cia nws ua noj rau ib nrab ib teev kom tuab lub txheej dub. Nws yog ib qho tseem ceeb los ua qhov no, vim tias cov tuab txheej yuav tev tawm kom yooj yim, thaum cov ntawv nyias yuav lo rau tooj liab thiab nyob twj ywm.

Tom qab ib nrab ib teev, tua lub qhov pa taws, tso cov tooj liab kub ntawm nws kom nws maj mam txias. Tsis txhob txias lub tooj liab nrawm dua, lossis ib zaj nkauj dub oxide yuav tsum ua raws li tus tooj liab. Tooj liab ntsws vim qhov txias. Thiab tooj liab oxide kuj nkag los ntawm nws. Tab sis lawv ntsws ntawm tus nqi sib txawv, uas yuam cov tooj liab dub oxide los ua kom tawg. Tom qab ib ntus, cov thooj loj loj yuav pib poob. Tom qab li nees nkaum feeb, tooj liab tau txias rau chav sov thiab feem ntau ntawm cov yeeb yaj kiab oxide dub tau ploj mus.
Kauj ruam 4
Siv koj txhais tes ntxuav cov tooj liab. Tus txheej txheem no yuav tshem tawm feem ntau ntawm cov me me. Tsis txhob tawm mus tawv ncauj. Tsis txhob khoov daim ntawv, txwv tsis pub koj tuaj yeem ua kev puas txheej ntawm cov tooj liab oxide uas koj xav tau.
Kauj ruam 5
Txiav daim ntawv thib ob ua qhov loj tib yam li thawj (rhuab). Khoov ob qho tib si kom zoo zoo, nyob rau hauv txoj haujlwm no lawv yuav tsum nkag mus rau hauv lub raj mis yas tsis kov ib lwm.
Kauj Ruam 6
Rhais cov tes rau ob daim paib. Txhawm rau ntxiv, txuas cov hlau los ntawm ntshiab tooj liab, thiab mus rau kev rho tawm - cov hlau los ntawm cov phaj nrog oxide. Sib tov ob rab diav ntsev nrog lub rhaub dej kub me ntsis. Ncuav cov sib tov sib xyaw ua ke rau hauv lub raj mis. Lub roj teeb tau npaj lawm!
