No such thing. Ask away!
!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.

Other commenters have good suggestions also, but one option I haven't seen mentioned would be to buy a powdered acid and make your own dilutions
It's easy to get citric acid in a dry form (like the crystal coating on sour candy), you can get 10 lbs (enough to make many gallons) of it for like $30-50 online. I put a small scoop in my dishwasher to keep my cups from getting foggy from our hard water, and I use it to descale our kettle and in our laundry, too.
Just be careful, acid dilutions are no joke. Whether you get the cleaning vinegar or make a citric acid solution for yourself:
use nitrile or latex gloves when working with the acid solutions
wear something to protect your eyes, glasses are probably good enough but goggles are better
if you have an acid solution and want to dilute it, pour the acid into the water, not the water into the acid!!!
flush your skin or eyes with water immediately if the acid gets on you or your clothes
These rules might seem like overkill but better safe than sorry!
Citric acid is slightly stronger than acetic acid so if I were you I'd make like a 20% solution to have a similar effect to the cleaning vinegar (so like 100 g powdered acid to 400 mL water). You might have to mix it on the stove so that the water is simmering to get the acid to dissolve.
Again, be careful! But as long as you're smart about it, take your time, and prioritize safety, you can definitely use this for descaling and cleaning (and cooking!)
TIL:
I feel stupid. I just realised why candy rots teeth.
🤯
Oooh it's even cooler than that!! You're spot on, acid is the problem. And acid from food, candy, coffee, etc. is harmful for enamel for sure.
But sugary stuff that isn't acidic also rots teeth. Why? Because the bacteria in your mouth do what's called lactic acid fermentation. Basically, when they take a sugar molecule and want to make "usable" energy out of it (in the form of something called ATP, or adenosine triphosphate), they end up creating lactic acid as a byproduct. In essence, the stuff living in your mouth makes acid out of sugar.
We also need to break sugar down into ATP, but we do something called cellular respiration instead. It uses oxygen and creates CO2 as a byproduct! That's why we need oxygen to breathe, and why we breathe out carbon dioxide. But, when you work your muscles hard (lifting weights, sprinting), you might use the ATP in your muscles faster than your body can make it with cellular respiration. In that case, your cells will also do lactic acid fermentation! That's what we're feeling when we "feel the burn" (well, that and micro-tears in the muscle, in some cases).

Thank you for the cool information!
This interaction made me feel like I was reading a comment in Reddit 10 years ago, I've missed that, thanks for that as well!
Agreed!!
Woah! Thank you so much for sharing!!
Hey did you ever do that experiment where you spit in a tube and see how long it takes to turn it acodic enough to damage teeth?
Cellular respiration, the Krebs cycle, oxidative phosphorylation, citric acid cycle, glycolysis... I miss having these processes in my head. I was such a biology nerd once.
