Flitz vs food grade mineral oil

I've been using flitz for a while and it seems to polish and stave off rust just fine (although I live in a fairly dry environment), and it's also safe for food prep. Is it worth it to shift to food grade mineral oil (like boker's or kurobara's) to treat steels such as A2 and 1080 or is flitz just better?
 
Mineral oil isn't for polishing.

It's a seal to keep the knife from oxidizing.

When I use and wash my blades, they still darken, and patina according to their steel type..... It's just that mineral oil is food safe.


Are you wanting to use your knives for food cutting?

I use them for anything from wood processing to food prep. I recently switched to carbon steels and been using flitz (as apparently it prevents oxidation, and it is quite effective at removing any eventual previous oxidation, as well as any scratches or little imperfections, all the while being food safe). I was considering buying mineral oil at first but flitz seems to do all that mineral oil does (aka preventing and eliminating rust) while also polishing your blade, and all while being food safe. Is there anything I’m missing about food grade mineral oil, or is there a reason why people tend to gravitate towards the latter rather than flitz?

From what I understand, after using Flitz you should be washing it off with soapy water. It's apparently non-toxic but it's still a polish with polishing agents that you don't want to be consuming. Mineral oil doesn't necessarily need to be washed off unless it has dirt or crap that has stuck to the oil. It's the same stuff they used for years as a laxative.

I think generally people use Flitz for removing patina/stains/rust and then wash the blade. Generally people use mineral oil as a coating to prevent rust. I wouldn't recommend using Flitz as a coating if you are doing food prep, although it's probably not going to kill you.
 
I didn't know flitz was food safe...?
most people don't comment on that.


I use wood and micarta handles and I like to keep them oiled as well. Mineral oil helps give them that not dried out look.
 
I never knew it either but Flitz says, non toxic.

So I wanna see someone use it for toothpaste. Because you know, someone on this planet has used it for toothpaste.
 
non toxic is not the same as food safe.
from the flitz website, regarding use on surfaces that contact food:

You mention countertops, appliances, and serving pieces; Is Flitz safe to use on surfaces in contact with food?
Yes, Flitz Polish is completely non-toxic. Flitz can be safely used on serving pieces, such as silverware, without any danger. After polishing, just wash the piece in warm soapy water and dry off as usual. The Flitz will not leave any flavor or smell behind.

Yeah I was a bit taken aback by that too. I don't think Flitz polish is food safe. I definitely wouldn't eat it. I don't even think it's good to have it on your skin for too long. Even if it is, I would still suggest washing your hands immediately after. I wear nitrile gloves whenever I use Flitz.

It's probably fine after you thoroughly wash it off. I definitely would not polish something with it and then immediately use it for food prep or eat with it without washing it first.
