Reply To: What's black and white and yellow all over?

Popa: the tears one expends in tefilla do not need washing out. Hashem collects them. But pungent sweat is a different story. And I’m not talking washing daily, weekly or even monthly. Even twice a year makes a real difference. Say just before Pesach then right after Simchas Torah should be the minimum for any uneccentric, mildly decent person…

Mod 20: Cleaners cannot make a yellow tallis white again but the cleaning does preserve the whiteness of a still-white tallis! BTW you dont have to spend $250 for a new tallis. And annual purchases are not necessary. Once in a few years in fine.
