Kutsuka ufa ndi mtundu wopangira zothira, ndipo ndichofunikira kwambiri pakhomopo. Pakadali pano, pali mitundu itatu ya ufa wotsuka pamsika, iliyonse ili ndi mawonekedwe ake

1. Mafuta ochapira ochapira komanso owotchera

Wamba kutsuka ufa, tinthu tating'onoting'ono tambiri tating'onoting'ono, kusungunuka mwachangu, thovu ndilolemera, koma zotsekerazo ndizofooka, sizovuta kutsuka, makamaka zoyenera kutsuka m'manja; ufa wochuluka wothira tinthu tating'onoting'ono, kachulukidwe kocheperako, thovu locheperako, koma chotsitsa cholimba (osachepera kawiri ufa wosamba wamba), wosavuta kuyeretsa, kupulumutsa madzi, makamaka oyenera kutsuka makina.

2. Phosphorous kutsuka ufa ndi non phosphorous kutsuka ufa

Mankwala ndi zowonjezera zowonjezera mu phosphate kutsuka ufa, koma phosphorous element ndi yosavuta kuyambitsa eutrophication yamadzi achilengedwe, motero kuwononga mtundu wamadzi ndikuwononga chilengedwe. Phosphorus yaulere yosamba ufa ilibe vuto ngati ili, lomwe limathandiza kuteteza chilengedwe cha madzi. Kuti tikhale ndi moyo wathanzi, tikulimbikitsidwa kugwiritsa ntchito sopo waulere wa phosphate.

3. Wothira mankhwala opangira mavitamini ndi mavitamini

Kuphatikiza kwa chopangira enzyme ndikowonjezera ma michere mu ufa wotsuka, ndipo zonunkhira zowonjezerazo zimawonjezeredwa mu detergent. Kutsuka ufa ndi enzyme kuli ndi ntchito yapadera yochotsa litsiro (monga madzi, inki, banga la magazi, banga la mkaka, madzi a nyama, banga la mkaka, banga la msuzi wa soya, ndi zina zambiri), nthawi yomweyo, ma enzyme ena amatha amasewera mbali yolera yotseketsa, kuyeretsa, kuteteza mitundu ndi kukulitsa utoto. Mafuta onunkhira osakaniza samangokhutitsa kutsuka kokha, komanso amapangira zovala zonunkhira ndikupangitsa anthu kukhala omasuka.
