@iPwnz , please don't confuse your parents even more, they are doing all this just to protect their families.
I lost both my parents years ago and seriously wish to have someone doing the exact same thing your parents are doing around me. This is family mate, the most precious thing one can have. Please don't hurt their sentiments. Having a few zinc/ vitamin C tablets won't harm you!! Which NE state are you from BTW? Always wanted to travel there, but beyond Guwahati and Shilong, never had a chance. Another thing in yhe bucket list.
Sorry, no idea about sanitizers. For last one year we are using what's provided by 3M, it smells like alcohol. I have seen some other alcohol swabs back home, but don't know/ remember any brand.
My job requires handwashing with soap frequently, so sanitizers are not much of use to me. Other than me everyone carries a bottle with them, they are probably all 3M, but I'm not sure.
