Rabbi Aryeh Lebowitz

So Mishmur explains that that's asr because the garment is made more beautiful in such a way, and that's similar to kibbutz.

So Yaqub Yosef points out that even though shaking off dust from a baguette is mutzah, because no water is used, scrubbing a stain, even without water, is going to be asr.

So according to the Mechaber, who says that dusting off is mutter, you're allowed to peel away a stain with your fingernail, even if the stain is not going to be visible, because that's similar to removing dust.

But you're not allowed to forcefully scrub the fabric against itself, because that's an act of kibbutz.

the one caveat to the Pesach of the Shulchan Aruch is this forcibly scrubbing the garment is to remove the dust that's the big thing but how does the Ramah reconcile these two Halachos so the Ramah in Sif Aleph

that shaking off dust that settles on a baguette is asr, but he seems to agree that removing a stain by folding the garment and slowly peeling away the stain is mutter.

So how do we deal with that?

So the Sharetzion discusses this.

And he refers to Rabbi Kik Weiger.

Again, I'm just not sure how much we should get into it.

What emerges is that there are two situations where you're allowed to remove a stain from your baguette.

Let's say you're wearing a jacket and you have a stain.

Number one is if after removing the thickness of the stain, it's still visible in your jacket, so you haven't really beautified the baguette.

And the other situation is if it's a type of stain that doesn't bother you at all, and you'd walk out of the house with that stain on your baguette.

So in that situation, you're even allowed to completely remove the stain with your fingernail, just like you're allowed to brush off dust from a baguette if the dust doesn't bother you.

However, the Bir Halacha says that an actual stain that's not just dust,

If you have an actual stain, it's not really so common that you'll be able to do that.

Meaning if let's say you have a dried piece of barley from the chalant that goes on your jacket, you could take that kernel off because it's like a feather falling on your baguette.

But using your fingernail to clean away a chalant stain that's on your jacket is usser unless it's so inconspicuous that it wouldn't bother you and you would leave your house with that stain during the week.

So, what's the best Eitzoh to remove the stain?
