Miswaak should be exclusively for only teeth not for any other purpose, we can use small brushes to clean keyboard...!

40 days! You must be using the same bristles for days on end. Isn't is unhygienic to use the same bristles for so many days? [Plus, the acid in the bristles eventually run out, so whats the point of brushing with them?]

20 days sounds just about right. Which means I'll have to cut off old bristles every 1-2 days.

You are right bro, I'll do it in around 20 days next time.
