Selected Halachos Related to Parshas Behar

By Rabbi Doniel Neustadt

The following is a discussion of Halachic topics related to the Parsha of the week. For final rulings, consult your Rav.

My Shabbos shall you observe... (26:2)


Laundering garments is prohibited on Shabbos for it is a tolada of one of the thirty-nine Shabbos Labors, melaben, Bleaching. While laundering usually entails the use of water and/or cleaning agents, removing dirt from a garment even without them may also fall under the halachic prohibition of Laundering. It is this type of Laundering which is the subject of our discussion.


There is a dispute among the Rishonim whether or not removing dust or other dirt particles from a garment is considered Laundering. Some hold that removing any speck of dirt from a garment, even if it is not absorbed into the fabric of the garment but is merely lying on its surface [like a feather or a loose thread], is Biblically forbidden since the garment is being transformed from "dirty" to "clean"(1). A second opinion maintains that removing any dirt, whether it is absorbed into the fabric [like dust] or not, is totally permitted, since a dusty garment is not considered dirty and removing the dust is not considered Laundering(2). A third, middle-of-the road view, holds that only dust which is trapped between the fibers of the fabric may not be removed, while dirt which lies on the surface, may(3).

The basic halachah follows the middle-of-the-road opinion(4), forbidding one to remove dirt that has been absorbed into the fabric(5) while allowing one to remove a feather or a loose thread that has landed on the garment(6) [using one's hands or a soft, dry cloth; a brush may not be used(7)]. Accordingly, one should be careful not to let his clothing fall on the ground and get dusty so that he does not come to desecrate the Shabbos(8). If, however, one's clothes should get dirty from dust, there is a mitigating factor which may permit removing dust from a garment: Removing dust from a garment is only considered Laundering if the person wearing the garment(9) is particular not to wear clothes in such a condition. In other words, if the garment is so dirty that its owner would not wear it(10), then cleaning it is considered Laundering. If the garment is not significantly dirty, i.e., its owner would not refuse to wear it(11), it may be cleaned so long as the following two conditions are met: No brush is used. The garment it is not shaken or scrubbed vigorously; it may be gently shaken or lightly dusted only(12). Can anything be done to a dusty garment [that is significantly dirty] whose owner has no other suitable clothing and is embarrassed to be seen publicly in such a dirty garment?

The poskim permit one to ask a non-Jew to remove the dust(13). While generally one may not ask a non-Jew to do anything that a Jew is not permitted to do on Shabbos, in this case he may, since as stated above, there are opinions who maintain that it is even permitted for a Jew to remove dust from a garment on Shabbos. [It is questionable, though, if one may instruct the non-Jew to use a brush(14).]

If a non-Jew is not available and the owner is embarrassed to be seen in public wearing a dusty garment, some poskim permit a Jew to clean the garment, provided that it is cleaned in an unusual manner, e.g., with one's elbow(15).


Halachically speaking, there are two types of stains: 1) a wet stain which is absorbed into the fabric of the garment, e.g. a ketchup stain; 2) a stain which is made when a piece of dirt or food falls on a garment and hardens there, leaving a stain(16). There are different rules for each of these stains:


A stain which is absorbed into the fabric and can be removed only with water or a cleaning agent is strictly prohibited to be removed on Shabbos. This is the classic Biblical prohibition of Laundering. Even if the stain is so insignificant that the owner will not be deterred from wearing the garment because of it, it is still strictly forbidden to remove it with water or any other cleaning agent.

If no water or cleaning agent is used, then it is permitted to remove the stain if it is insignificant and would not deter the owner from wearing the stained garment. If the stain is significant, however, it is prohibited to remove it if the stain will be removed completely, i.e., it will leave no mark whatsoever on the garment. If, however, the stain is only partially removed - some mark will remain - it is permitted to be removed. Two conditions apply:

No brush may be used.

The stain may not be scrubbed away; it may only be gently wiped off with a dry cloth or removed by hand, with a knife, etc(17).

Dirt which adheres to the garment's surface

A stain which results from dirt or food that has attached itself to a garment can also be removed if it will be only partially removed or when it is "insignificant", as explained earlier. It can be removed either by scratching it off or by rubbing the reverse side of the material until the dirt is dislodged.

There is, however, one notable difference between this type of stain and the wet stain which became absorbed into the fabric of a garment. The removal of this type of stain is subject to the laws of "Grinding", a forbidden Shabbos Labor. If the dirt or food has dried or hardened, scratching or peeling it off will cause it to crumble, a Rabbinical violation of the prohibition against Grinding. Therefore: If the garment was stained by mud and the mud has dried, it may not be rubbed off - even if the stain is insignificant or will leave a mark - because of the prohibition against Grinding(18). If the garment is stained by unprocessed food which grows from the ground, e.g., fruits and vegetables, it may not be removed because of the prohibition against Grinding. But a stain from food which has already been ground, like baby cereal, may be removed because Grinding does not apply to previously ground food(19). Beans or potatoes from cholent are not subject to the prohibition against Grinding, since they are cooked so thoroughly that they are considered "previously ground", and the prohibition of Grinding does not apply to them(20). Even when the prohibition of Grinding applies, it is permitted - when necessary - to ask a non-Jew to remove this type of stain on Shabbos(21).


1. Sefer ha-Zichronos, quoted by Magen Avraham 302:4.

2. Tosfos, Shabbos 147a and many other Rishonim.

3. Rashi, Shabbos, ibid. as explained by Rama and Gra 302:1, and other Rishonim.

4. Rama, Shulchan Aruch ha-Rav and Aruch ha-Shulchan strongly recommend that one be stringent and follow this view [but do not absolutely require it]. Chayei Adam and Mishnah Berurah, however, are of the opinion that the basic halachah is in accordance with this view and one may not be lenient.

5. In theory, there may be some dust which lies completely on the surface of the garment and is not absorbed into the fabric. In practice, however, this is almost impossible to determine. See Salmas Chayim, second edition, 283, concerning surface dust on shoes.

6. A minority view rules like the first opinion that even feathers and threads are prohibited; Chayei Adam 22:9 quoting Magen Avraham; Ben Ish Chai, quoted by Kaf ha-chayim 302:11. See also Aruch ha-shulchan 302:9 who rules like this view in the unlikely event of a person who is reluctant to wear a garment because of the feathers, etc. See Machazei Eliyahu 44-4.

7. Beiur Halachah 302:1.

8. Mishnah Berurah 302:6.

9. It remains questionable whether or not another person [who is bothered by the dirt] can clean the garment if the wearer himself is not particular; Beiur Halachah 302:1.

10. This is determined by assessing the individual wearer's willingness to wear a dusty garment on weekdays, even if he would not wear it on Shabbos, Yom Tov or other special occasion; Harav S.Z. Auerbach (Shemiras Shabbos K'hilchasah 15, note 89 and Tikunim u'Miluim).

11. While this is sometimes difficult to determine, there are two general guidelines to follow: 1) One would normally be reluctant to wear dark (black or dark blue) clothes which are dusty but not brightly-colored clothing; 2) One would normally be particular not to wear new, or freshly laundered clothes which are dirty, but would be less particular if the clothing were obviously worn or faded.

12. Mishnah Berurah 302:36 and Beiur Halachah 302:1 and 7.

13. Mishnah Berurah 302:6.

14. Since this may be prohibited according to all views. If the non-Jew uses the brush on his own, to make his job easier, he need not be stopped.

15. Misgeres ha-Shulchan on Kitzur Shulchan Aruch 80:80, quoted by Minchas Shabbos 80:143. See Beiur Halachah 302:1 who seems to rely on this only when the garment is clearly not new or newly pressed. See also She'arim Metzuyanim b'Halachah 80:36 who disagrees with this leniency.

16. A third type of stain is one where the food was neither absorbed into the fabric nor dried and hardened; it merely remained on the surface and could be easily flicked off, e.g. a noodle. This type of stain is permitted to be removed according to the halachah described earlier, since it is similar to a feather or a loose thread which may be removed.

17. Entire paragraph based on the view of the Mishnah Berurah 302:11 and 36 and Beiur Halachah. This is alos the view of Da'as Torah 302:7. Note that there are poskim who are more lenient and allow a stain to be removed even when it will be completely removed as long as it is not scrubbed vigorously; see Aruch ha-Shulchan 302:9; Ketzos ha-Shulchan 116.

18. O.C. 302:7.

19. See Rama 321:12.

20. See Shemiras Shabbos K'hilchasah 6:9 and 15:28.

21. Mishnah Berurah 302:36 and Sha'ar ha-Tziyun 44.
