An unofficial chapter of the popular Dull Men's Club.

https://dullmensclub.com/

1. Relevant commentary on your own dull life. Posts should be about your own dull, lived experience. This is our most important rule. Direct questions, random thoughts, comment baiting, advice seeking, many uses of "discuss" rarely comply with this rule.

2. Original, Fresh, Meaningful Content.

3. Avoid repetitive topics.

4. This is not a search engine
Use a search engine, a tradesperson, Reddit, friends, a specialist Facebook group, apps, Wikipedia, an AI chat, a reverse image search etc. to answer simple questions or identify objects. Also see rule 1, “comment baiting”.

There are a number of content specific communities with subject matter experts who can help you.

Some other communities to consider before posting:

5. Keep it dull. If it puts us to sleep, it’s on the right track. Examples of likely not dull: jokes, gross stuff (including toes), politics, religion, royalty, illness or injury, killing things for fun, or promotional content. Feel free to post these elsewhere.

6. No hate speech, sexism, or bullying No sexism, hate speech, degrading or excessively foul language, or other harmful language. No othering or dehumanizing of anyone or negativity towards any gender identity.

7. Proofread before posting. Use good grammar and punctuation. Avoid useless phrases. Some examples: - starting a post with "So" - starting a post with pointless phrases, like "I hope this is allowed" or “this is my first post” Only share good quality, cropped images. Do not share screenshots of images; share the original image.

You can use citric acid too, or at least I did

Lactic acid is a no no though apparently

Lactic acid is a no no

And sulphuric is right out.

Oh… I guess I’ll just put away my HCl, HNO3, HF and other goodies.

Citric acid works great for this. A $10 bag will last the rest of your machine’s life, and there’s no weird aftertaste like can sometimes happen with vinegar.

I've always used vinegar to descale my coffee machine.

Espresso maker? Living close to edge aren't you sport.

As long as your coffee mug still has 10+ years of black tar in it.

You can get citric acid at most brew/winemaking stores that works fine.
