“I got no car and it’s breaking my heart, But I’ve got a driver and that’s a start!”
General answer: it cannot be done (or maybe it can – I was not familiar with the Schick product that @Little_Nemo mentioned). More specific answer: I don’t recall this ever being a problem with traditional double-sided razor blades in the classic handle that our fathers and grandfathers all had, before we were inundated with an infestation of the “modern” multi-blade disposables. I’ve been meaning to order some of those old style grandpappy things (available on Amazon, but practically nowhere else) but for decades now my solution has been some combination of (a) electric razor, (b) modern disposable razors with just one blade – these still clog but you can swipe them with a tissue to more or less unclog them, and (c) just resigning myself to looking like Santa Claus, which I do from time to time.
I just knock it out on the edge of the bathroom sink/basin.
Ultrasonic cleaners work great for similar purposes, in my experience. I use them to clean the heads on electric razors (which have similar gunk and similarly fine tolerances, even if the geometry is different).
I’m sure you know this, but they make these artificially long vids because YouTube somehow rewards them for it. If a video is longer than X, there will be an advertisement half-way, so YouTube and the vlogger make more money. X used to be10 minutes, but in 2020 it was shortened to X = 8 minutes. Here’s a 5-minute video explaining it. 
Compressed air??
Or, you know, just buy normal double-edged razor blades. Probably cheaper, too.
Back to the thread… from a chemical Safety Data Sheet
Odor: characteristic
not to exacerbate this hijack too much, but try Duane Reade/Walgreens/CVS/what drugstore does not have at least one brand of plain safety-razor blades?
Way back when Lifehacker was still a thing, they had a listicle about optimal shopping at Ikea. One of the items was something like: You’ll save time and distance on your shopping trip if you park your car in the no-parking loading zone near the exit, and leave it there while you go shopping for stuff.
And you’ll save a lot of money if you load up your car and drive off without paying.
If you look carefully, you can often find conveniently located parking spaces marked with a wheelchair symbol.
Check out Henson Shaving. Their razors are great, and Canadian made. They sell 100 blades for less than $13.
I use a Piksters size 3 interdental brush every so often. Pick out the stuff behind the blades with it, Then just gently run the brush @ 90° along the blades while rinsing under hot water. The bristles on the picks are really soft plastic and don’t seem to harm the razor blades.
Wow! Thank you for that tip! CAD $89.99 seems pricey for a basic handle for a double-edged blade, but it’s probably worth it if you can’t get it anywhere else. I’ll order one if I can pick up a stash of regular blades, and get back to my old style of shaving!
Back when I shaved, I bought the cheapest disposable available – they’re currently about $30 for a pack of 200 on Amazon, and I’m sure you could find them in higher bulk for even less. That’s about $0.15 per razor, and I’d just toss it out after a single use.
Horrible for the environment, and perhaps pricey over a lifetime (let’s see: about $3,500 for 65 years of daily shaving, no idea how that compares with anything else.) I’m a bad man but at least I don’t go to Starbucks.
I’ve probably saved thousands of dollars by not shaving for the last 59 years.
I do that and also use an old toothbrush just for this task.
To save money at McDonald’s drive-thru, skip the first window and just go to the second window.
You’d be amazed at how many students in cafeterias don’t know this one.
I needed paintball CO2 canisters filled for my water carbonation system before I found a gas place to do it cheap, so I was at a Dick’s Sporting Goods place.
I was getting irritated by how slowly the process was proceeding. I almost walked out several times. When I was finally paying the cashier asked for ID. I told her I left it in the car. No problem, says she, just give me your birthdate. I’m in my 60s. On a good day I can pass for someone in their late 50s. This wasn’t a good day.
I gave a date. She entered it and got an error message. She reentered the date . Rinse, repeat, over and over. She is flustered and confused. She gets a manager and shows the screen to him. He points out that the date entered makes me 135 years old. She still doesn’t understand. He overrides and I pay.
(Yes, I was a dick. In my defense, the store’s name was Dick’s)
I knew a guy who was a veterinarian. He went through a messy divorce. He kept the house, but she took the contents of the house. He had a big, empty house.
He was at an auction. There were chairs which he thought would be perfect for his business waiting room. He bid and won on a price per chair. There were dozens more than he needed, but they were dirt cheap so he bought them all.
He used ten for his waiting room. The other three dozen or so he took to his home and just lined the living room, dining room, and entryway with chairs.
That was bad enough. But over the next decade the chairs at his office were beat up pretty badly. Whenever a chair looked like shit, he’d take it home and swap for a nice chair. He didn’t get many visitors at home, but those who saw his situation get a chuckle.
