I dunno. After each shave I take the blade out, rinse it and place it on a block I have for that purpose. The razor I rinse and wipe down. Never had a problem and we don't have soft water either.
Most times Dawn and a toothbrush will do the job.
I'm calling pics or it didn't happen. OP's razor is stainless steel. If you can etch SS with BKF and a toothbrush, I'd be genuinely interested in such sorcery. I've included a pic of my 6 year-old SS ATT razor that I've used this method on consistently. And just for fun I threw in a brass head as well - brass being considerably softer than SS.
Both cleaned prior to pic with BKF and toothbrush.

I have etched stainless cookware as well. BKF is a last resort.we have etched all clad stainless steel lids with bar keepers friend on accident. The active ingredient is oxalic acid. There is a reason the instructions say leave the paste on for just 1 minute or so. If you leave it longer it will etch the steel.
Try some toothpaste or baking soda.Here are the before and after pictures. What I have tried so far:
(1) soak in laundry rinse for a few hours then scrub with ultra soft tooth brush (my only option)
(2) soak in hot water for a few hours (water cools off obviously) then scrub with same ultra soft toothbrush
(3) use alcohol wipe to try and scrape off some of the difficult bits.
As you can tell it's still not clean and I have no idea how to get the various holes cleaned.
Nice try, NotThatMatt, but the OP razor is a Feather AS-D2. It is not raw stainless steel like your ATT razor. It is coated with an extremely thin layer of chrome. BKF could potentially mar the coating.

NotthatMatt your razors look to be tumbled finishes so you may not notice anything other than a swirl here or there. Not adised for plating or high polished finishes.
I would LOVE for someone to show me an example of this destruction. Seriously, I restore a lot of vintage things and I rely on BKF and GoJo for 90% of it. BKF if it's organic matter (including oxidation), and GoJo if it's petroleum based gunk. Naptha if your doing really intricate watch parts. I've tried so many things to clean and restore, and I've found what works for me. If you don't want to use it, by all means don't; totally up to you. But I keep hearing "potentially" and "accident" and "may not." No one is showing pictures of any of this. If this is really happening, it's in my best interest to be educated about it so I don't mess up something that really matters. What I'm telling you is that BKF is far less abrasive than any metal polish, and far more productive than vinegar or toothpaste or eye of newt or whatever. But again, don't use it, not my business.
What I find more often than not is that people tend to look at precious things and believe them to be perfect. Even under layers of gunk. But that gunk is filling in some gaps; when we actually remove the gunk, and reveal the scars, do we blame ourselves? or oxidation? or time? or the 100 times we dinged our pot lid against a spatula? Nope, we blame the cleaner. Cuz those blemishes weren't there before I cleaned it.
At great peril to my own collection of razors, I went upstairs and proceeded to clean any number of things I could find that would persuade the casual reader. A brass Gillette New that I had replated in chrome (chromed nickel anyway). A Fatboy also plated the same way. A SS RazoRock Hawk with a bright finish. And just for fun, the cap of my Schick type C Injector that has a whisper of gold plating over brass. You could breath on it and take the gold off. Magnification to show that there are swirls, or brush marks, or etche.
noSo here is my genuine and humble request. Please take a picture and post. I've put several hundreds of dollars worth of my own stuff on the line to make a point. Please return the favor. And if anyone want's to really drive home their point, take a before and after shot where you were able to etch something, and then etch it again in a predictable way. I'm not looking for anyone to destroy anything of value, go to town on a spoon in your drawer. Anything.
I avoid all this by just giving it a good rinsing under hot water and wiping it down after each shave. It only adds an extra minute to the process but pays dividends later. Then every month or two a lite scrubbing with Dawn and a soft tooth brush. Problem solved...
