According to this article, most Poskim do allow one to brush one's teeth on the three minor fasts, especially if they are going to be in some level of discomfort.
..While the Kaf Hachaim (OC 567:13) forbids rinsing even with less than a revi’is, most poskim are more lenient, especially when one is uncomfortable. Thus, the Rema (Darchei Moshe OC 567:2), ...

It is logical to think that the priests were careful, so that the blood only landed on the floor, and not on the actual curtains.
Regarding Beit HaMikdash, the whole place was covered with aqueducts and water channels from the surrounding rivers/lakes. These would lead the blood (and other remains) outside.
For example, the Mishna in Yoma 5, 6 talks about ...

Rabbi Ribiat discusses this in The 39 Melochos (in the corrected edition, Misrad Hasefer 2004), Section 3/C/b-3.
He says that most poskim (notably, ערוך השלחן שכ"ו י"א) rule that one is allowed to use liquid soap on Shabbos, because Memarayach (a toldah of Memachaik) does not apply to liquids.
However, some poskim (notably, אגרות משה שו"ח ח"א קי"ג) rule ...

To supplement, not supplant, Cauthon's good answer, I'll note that the mishna (Midos chapter 3) says that the altar and its ramp would be cleaned every Friday with a cloth, because of the blood. (This is Rabi's statement, but the commentaries note that he's explaining and not arguing on the other rabbi in the mishna.)
(It's not completely clear to me ...

Regarding washing on Yom Kippur, the Tur (OH 613) writes:
ביה"כ...ואם היו ידיו מלוכלכות בטיט וצואה מותר לרוחצן שלא אסרו אלא רחיצה של תענוג ...וכן בכל היום אחר שעשה צרכיו וקנח או הטיל מים ושפשף בידיו וכתב גאון מי שהוא איסטניס וצריך לקנח פניו במים ואין דעתו מיושבת עליו כל היום עד שיקנח יכול לקנח בי"ה וכ"כ רי"ץ גיאת אם יש ליכלוך על פניו או על גבי עיניו יכול ...

Chicago Community Kollel Parsha Encounters Oct 23, 2009 discusses the issues with bar soap.
The Rama (326:10) writes that it is forbidden to wash one's hands with
soap on Shabbos. Three reasons are given for this prohibition. The
Rama explains that using soap on Shabbos causes it to turn into
liquid, which is a violation of Nolad (creating a new ...

The Radvaz (Teshuvos, chelek aleph: 135) and the Chayey Adam (119:6) explain that the reason we clean cracks and crevices from chametz is because maybe we may come to eat it on Pesach (because it might get into food).
Otherwise, the Gemara Pesachim on 6b says that crumbs are not important at all. The Magen Avraham (S.A. 434) even says that crumbs are "batel"...

The best way to wash a wool tallit katan is by hand washing it. Washing machines and dryers can severely mess up a wool tallit katan if you're not careful. I would suggest hand washing the tallit katan in a mild fragrance-free hypoallergenic detergent, in cold/warm (not hot) water, and then hang it out to dry.
If you have a trusted dry-cleaner, some have ...

Today's HalachaText said that clothing should be worn for at least 30 minutes. I asked them for a source and they said this number came from Rav Elyashiv Ztl.
שוב מצאתי I was looking for something else in Rabbi Simcha Bunim Cohen's Laws of the Three Weeks, and found that he quotes Rav YS Elyashiv there as saying a half an hour (page 85); in a footnote he ...

In addition to the other answers, we have some evidence that blood did land on the veil in the Holy of Holies when the Kohein Gadol (High Priest) sprinkled it there on Yom Kippur, and that they weren't too good about cleaning it.
The gemara in Meilah 17b quotes the sage R' Elazar Bar R' Yose as having seen the curtain in the treasury in Rome, and it had ...

Buy something what is called WOOLITE. This is special detergent for wool, you can find it in every supermarket. Put your talis in the bucket, fill with warm, not hot water, add cup of Woolite and leave it for 3-4 days.
For better effect you can change water ever day and fill the bucket with fresh water, don;t forget to add some woolite.
After 3-4 or more ...

I relayed your question to the sofer who maintains our scrolls. Here's what he said (my notes from a verbal conversation):
The "dust" that came off of the scroll is white mold, not the parchment flaking off. (Not all mold is black.) You should therefore clean your scrolls in a well-ventilated place and consider wearing a mask. Because he does this a lot ...

The page you link to indicates that the solution disinfects the lenses. Per Torah.org a disinfecting solution may not be used on Shabbos.
On Shabbos, the lenses may be soaked in saline solution [so that the
lenses do not harden] but not in disinfecting solution.
See also Rabbi Kaganoff.

The OP mentions "less than a kazayis" as well as "crumbs". It is proper to note that the two terms are not automatically the same in Halachah. A question can be asked as to when does a small piece of chametz achieve crumb status?
There are two concerns of chametz on Pesach related to the OP(besides the prohibition of deriving benefit):
Not to own chametz.

There are two melachoth that could be violated during an act of squeezing - dosh/mefarek (extracting) or melabein (cleaning). With regard to the former, your point is to absorb the moisture into the napkin, not to release it. If some was unintentionally extracted as well, that would be considered a davar she'eino mithkavein (unintentional) and therefore ...

I got this in an email from a "dailyhalacha" service:
During the Nine days (beginning Rosh Chodesh Av) the custom is that
one does not wear freshly laundered clothing. Therefore, one should
wear all the clothing one will need during the Nine days for a short
while (according to many Poskim - 20 minutes), sometime before the
start of the Nine days. ...

A similar question was posted yesterday, regarding a talis katan.
To quote from ezra's answer:

Probably the issue is hashmaat kol (leaving a noisy device running on shabbos that is considered a profanation of it's sanctity). - https://www.naaleh.com/hashmaat-kol-noise-on-shabbat-v5n9

I always bring my kittel to the dry cleaner. It always comes back nice and clean (and freshly ironed).

Your friend's explanation has its source in the Gemara Pesachim 8a. "Rava says: A courtyard does not need to be checked for chametz since crows are to be found there." This is the accepted Halachah.
You are right in that your lawn is your property/domain. It is true that one may not keep chametz there over Pesach, just like the house. However, we need some ...

As long as there's no reasonable chance of encountering it on Pesach, then no. (This comes up more often as people try to find any chametz behind their fridge, but the same idea -- try sweeping underneath if you can, but you don't have to move the fridge!)
Rabbi Hershel Welcher in Queens has a pre-Pesach shiur on this. "Let's pick one day a year for people ...

R. Moshe Stern (Be'er Moshe 6:62) explicitly permits one to clean glasses on Shabbos, by both blowing on and wiping the glasses. He does not cite the Rema's ruling (OC 319:17) in which he finds spitting [into the wind] liable of winnowing. R. Binyamin Zilber too (Az Nidbaru vol. 13, no. 14) permits the above case and likewise does not discuss winnowing. My ...

I don't know about the rest of the week, but as a starting point, we are enjoined to make an effort before the onset of Shabbat.
It writes in Shulchan Aruch (Orach Chayim 262:1):
לקדש השבת בשלחן ערוך ובכסות נקיה: ובו ג"ס
יסדר שלחנו ויציע המטות ויתקן כל ענייני הבית כדי שימצאנו ערוך ומסודר בבואו מבה"כ: הגה ויהיה שלחנו ערוך כל יום השבת וכן המנהג ואין ...

It says in Pesachim 111b " איסרא דעניותא נבל שמיה" "The angel over poverty is called dirt"
Rashi, however interprets it as being unclean regarding bread

Some say yes, some say no.
The issue is not only wringing, but also whether the paste turning into froth is considered nolad, something new that came to be on Shabbat. For a comprehensive overview of the issues involved and which poskim have ruled what, see Yabia Omer Vol. IV O"H #30, where Rav Ovadia rules that it is permissible to brush your teeth using ...

I just bought this in Israel (it helps to keep the tzitzis from being tangled, similar to the sock method mentioned in one of the answers, but this allows the water to reach the strings so that they get cleaned well too):

Great trick for keeping zizit from tangling.
My wife takes my cotton begged zizit and washes with other clothes, buy she has a great trick for making sure the actual zizit strings don't get tangled.
She takes the four zizit and puts them inside a sock, then makes a knot of the sock, with the zizit inside and tosses it in the washing machine with ...

People have told me soaking it in ammonia also works. I soaked my oil glasses in ammonia for a couple of days and it worked pretty well. I did keep it outside while I was soaking it because of the smell and because I have little kids around.
