Chifukwa cha mafunso awa okhudzana ndi chilengedwe ndi kuchuluka kwa mankhwalawa akugwiritsidwa ntchito masiku ano, zikuwoneka kuti ndi bwino kuchepetsa kugwiritsa ntchito kwathu pamene tingathe. Yambani posankha ndi pocketbook yanu ndipo musagule mankhwala ochapa zovala ndi opatsa kuwala!
Njira Zapamwamba Zotsuka Nsalu
Kuvala zovala mumadzi a mandimu ndi madzi musanayambe kutsitsa ndiyeno kuwapachika pamzere wouma dzuwa limagwira ntchito ngati chithumwa. Pulogalamu ya hydrogen peroxide ndi madzi imathandizanso. Njira yowonjezera yogwirizana ndi kugula limodzi mwa mabungwe ambiri omwe si a chlorine omwe amachokera pamsika, monga Seventh Generation ya Natural Oxy Stain Remover .
