Kukonzekera: botolo 1 lachimbudzi chotsukira, burashi yayikulu 1, misuwachi yotayira 2, ndowa imodzi yamadzi ndi gwero limodzi lamadzi.
woyera:
1. Gwiritsani ntchito ndowa potunga madzi.
2. Tsukani fumbi pamwamba pa gudumu ndi madzi aukhondo kaye.
3. Sulani dothi lakuda ndi lachikasu pamwamba ndi chotsukira chimbudzi, ndipo sukani m'mbali ndi m'makona ake ndi mswachi wotayidwa.
4. Pambuyo poyeretsa ndi madzi oyera, zinathetsedwa. Kupatula kung'ambika kwa gudumu la magudumu lomwe silikanatha kutsukidwa, zonyansa zina zonse zakuda ndi zachikasu zidachotsedwa. Ndine wokhutira kwambiri.
Pukutani mawilo ndi siponji yonyowa, yomwe imachotsa fumbi ndi dothi zambiri zotsalira poyambira-kukweza, kuteteza pamwamba kuti zisakanda mawilo.
Chotsani fumbi ndi zinyalala pogula ndi kuyeretsa mawilo a aluminiyamu aloyi m'sitolo, kupewa zinthu zoyeretsa acidic. Sakanizani madzi okwanira ndi choyeretsera mumtsuko. Siponji ankawaviika mu ndowa yoyeretsera wothandizila ndi madzi. Finyani chidebe cha siponji kuti musawononge zoyeretsera. Tsukani mawilo ndi siponji.
