Clean in india is so far from being clean in Canada

So we wash our hands before every meal and we are always amazed at the amount of dirt that comes off our hands. This place is plain and simple dirty. In India its normal for me to go 3-4 days without a shower. I've been wearing the same pair of pants for the last 10 days, possibly more I've lost count. You recycle your clothes all the time. Ofcourse we get our laundry done but it never comes back perfectly clean so you just continue to build ontop of the dirt.
