Depende din kung paano mo gamitin yung disinfectant.I started using disinfecting wipes for our door knobs,remote controls basta anything na madalas hawakan sa bahay and I use half isopropyl alcohol half water to disinfect his toys so far its working!Our state has one of the highest case of flu here pero so far wala pang nagtatrangkaso sa amin..also,I make sure to wash our hands esp pagka galing ng school and change his school clothes immediately kasi dun sya lagi nahahawa ng sakit sa mga kaklase nya.lastly,I prefer the chemical brands than the natural or organic brands...I tried it,doesnt worked tsaka me kamahalan pa.
