People have been cleaning their ears with cotton swabs for years. What other tools are being inadvertently used wrong?

I swear every time my spouse tries to use wd40 I have a stroke. We have several kinds of specific lubes for different situations ffs, all in the same easy to access bin, stop trying to use wd40 as a catch all super lube that's not how it works.
People don't send letters much anymore but please don't lick the envelopes. Just dip a finger in water. Just as easy, less germy, and doesn't cause a lingering chemical taste.
Nobody seems to understand how to use dental dams. Look it up, stay safe people.
- Greetings from my wife. She wanted me to send you this picture:
  
  Having grown up with Red Green I'm team duct tape 100% but I'll die on my WD40 hill
  
  Hehe. Sometimes it's just the way it is. We all have boundaries and our personal limits. 😆
  
  Duck*
  
  Both have been used at different times so the words are effectively interchangeable. However I'd also like to point out that in my example specifically duct tape is the proper word to use as that's how it is used in Red Green:
  
  As a huge fan of ol' Green (born & raised Michigander), and I don't recall him ever using it on ducting, yet I can easily remember a plethora of examples where he used it for its hydrophobic sealing properties.
- Wd40 isn't lube at all, it's a solvent. Though the wd40 brand does make a whole lot of lubricants too.
  
  Yea, it's called Water Displacement formula 40. A penetrating oil mixed with stuff. Not nearly as goid as grease
  
  Grease isn't always the right thing either. For plastic-on-metal, you definitely don't want grease.
  
  Didn't know that. Turns out some lubricants cause plastic to swell or harden and crack. Recommended to use silicone or special lubricants. https://readingplastic.com/choosing-the-right-lubricant-for-plastic-parts/
  
  Hmm, most my door hinges have a little plastic ring on them I assume to reduce squeaking. Sounds like I should switch away from grease for those. Didn't realize this
- But those envelopes are tasty...
  
  It's so sad stamps don't need to be licked anymore.
  Nothing beats a licked envelope followed by a stamp chaser.
  
  Do you let out an airy 'aaah, yep' and slap the envelope onto the table, too? I just kinda want to see someone exasperated and hunched over a USPS counter being like 'another!' as they pull letters out one at a time and the register worker hands them just a single envelope and stamp each time.
  
  I guess I could see them being tasty if you've got the palette of an 80 year old smoker who grew up eating poverty suspended in aspic.
  
  Lol, that's me!
- Casually suggest using WD40 as lube for the next sexy time. When they say "what," you can say "why not? You use it for everything else." Maybe it'll click.
  Of course, this advice may negatively impact this, and possibly several future potential sexy times, but it's a small sacrifice if it keeps people from using god damned WD40 as a fucking lube.
- Dental dams.
  I know what it is yet never found it selling.
  Licking envelopes.
  There was a time when the glue was somewhat sweet. I grew out of it quick enough - wasn't willing to stick paper in my mouth - but not quick enough to not build that memory.
  WD40
  It has a very wide range of uses but there is a limit for it.
- So... being one of those spouses who uses wd40 on everything. Do you have link to some easily understandable info on when to use the right lubricant?
  
  One easy rule of thumb is if you're looking to lubricate something WD40 is never the correct choice. It's not a lubricant, it's for cleaning/breaking shit loose.
  
  The only thing worse than people using WD-40 instead of a better product, are the mental gymnastics performed by people pretending a product which is 35% oil and sold as a lubricant, actually isn't.
  
  If you want to use it as a lubricant go ahead. Just be prepared to have to do it more often than you would with a more suitable product.
  
  Wd40 is good for preventing rust, and helping to get things that are seized moving again. If you want to lubricate a door hinge, something like 3 in 1 oil is a good choice.
  
  Yeah it has uses but specifically people seem to use it as a catch all which is where the misuse comes in. I've used it to unfuck rusty screws before it is great at that
  
  Not OP, but not really. The real issue is that WD-40 is kinda like duck tape. It definitely has its uses, and hoo boy are there a lot, but it's too much power too fast, and corrupts young engineers and repair people into using it as a "fix all tool."
  Sewing machine oil is a wonderful penatrating oil. This is what you use on tools inside the house that mostly just get a bit dusty.
  WD-40 does contain some oils and can be used as a penatrating oil, but it's mainly a cleanser. You shouldn't leave it on anything that will be damaged by cleansing solutions, so motherboards, plastic in general.
  For a general use oil, for hinges and things, I will clean with WD-40, and then once I have cleaned it I wipe it down with 3 in 1 penetrating oil, for things like door hinges, or sewing machine oil for more delicate tools.
  Edit: I had not seen the flowchart below when I wrote this comment, but it illustrates my first point beautifully
  
  Upvote for correct use of "duck tape" 😁
  
  Thank you, I'll try to remember this next time something squeaks around the house :)
  
  Mechanical stuff you're looking at grease, oil, penetrating, or dry. I found this with a quick search for more info. Personally I've found white lithium grease to be the best general purpose one for my needs (squeaky hinges, drawer wheels) but it can be pretty messy if used in the wrong spots. For most fast moving things with fine parts (like a bike chain) I really like wax lubes but they can get gummy sometimes so silicone works well too.
  For sex I prefer water based because it is easier on toys and doesn't make me fear for my life when trying to wash off in the shower after. It isn't usually as long lasting as silicone based but it can be 'revived' with some water or other fluids. Anal I prefer oil based (shout out to Boy Butter because the name and logo are ridiculous but it works amazingly) but it also damages condoms so like if you're not using an insertable go for the protection and silicone combo. For oral I'll concede that wd40 actually has a use case here.
  
  Ive never used wd 40 during sex before. I'm sure it'll be a surefire way to get an insurance covered vasectomy, also known as testicular cancer.
  
  I'm supposed to get mine removed next year but insurance is giving me the middle finger. Hoping my WD40 habits get me into the doctors sooner and with insurance.
  
  Thank you for that... thorough explanation. You really know your lubes :)
  
  If you're looking for an actual "all-purpose" lubricant try tri-flow lubricant. It's technically a chain lube but it works pretty well for most light duty household stuff and it sticks around a whole lot longer than WD40. Generally wherever you think WD40 is a good idea that stuff will usually work better. The only downside is that it smells strongly like bananas for a while after you spray it on because it contains banana oil. It's not a bad smell but it's definitely noticable.
  WD40 is a bit of a catch all. It kind of does a lot of things but it isn't great at any of them. It's kind of a penetrating oil for busting things loose but it doesn't work nearly as well as an actual penetrating oil. It's kind of a part cleaner but it won't work nearly as well as an actual part cleaner. It's kind of a lubricant but it won't work nearly as well as an actual lubricant. If you had one can of stuff to bring with you to a deserted island then WD40 would be the best thing to bring. But other than that there is always a better dedicated spray for whatever you want to do.
  
  Simple. WD40 for most things, WD40 silicone for vinyl windows. Grease for bike chains.
  
  My soul 😭
  
  😂
- I had to look up dental dams, TIL.
  
  I knew what they were but I am still not understanding the connection to WD40.
  
  I have tmj and so my jaw can lock shut sometimes. WD40 can be used to quickly un-seize my jaw so I can get some proper lube in there and keep enjoying what's on the other side of a dental dam.
  
  Glad to spread the word! They're an important piece of PPE that a lot of people overlook
- Burns the ding dong
  
  For real, those envelopes chemicals are no joke
  
  RIP susan
