Oh man, you have heart to be willing to do something like this, I must say. I've left used "makas" out several times in the strainer for a couple of days (I can get that lazy once in a while) and woweee that stench is rancid. Especially if you use enough milk in your brew. You might want to wear a surgical face mask for this one. Unless you're the minority who enjoys basking in air from a barnhouse.
