Utywala obunogxininiso lwe 75% Idla ngokugqabhuka xa ibekwe elangeni. Ukuba lulwelo olunokutsha, inokukhanya kwe-20°C, nasehlotyeni, ubushushu bangaphandle bunokunyuka ngaphezu kwe-40°C, kwandisa kakhulu umngcipheko wotywala ngokuzenzekela kunye nokuqhushumba elangeni.
Ukugcina ngokukhuselekileyo 75% utywala, kufuneka igcinwe kwindawo epholileyo, indawo enomoya opholileyo apho ubushushu bungagqithi kuma-30°C. Isitya kufuneka sivalwe ngokukhuselekileyo kwaye sigcinwe ngokwahlukileyo kwii-oxidizers, iiasidi, iintsimbi zealkali, kunye neeamines ukuthintela nakuphi na ukusebenzisana okuyingozi. Kucetyiswa ukuba kusetyenziswe izibane ezingagqabhukiyo kunye neenkqubo zokungenisa umoya, kunye nokuvalwa okungqongqo koomatshini kunye nezixhobo ezinokuvelisa iintlantsi.
