Remove Lacquer on knife

[OllieOllie]

Hi everyone,

I need some help with removing lacquer from a knife. I tried using acetone, but it didn't work. What other options do I have besides using sandpaper?


Thanks,
Ollie

Flitz

Thanks! Does cape cod work the same?

Hmm not sure, I've never used the product specifically, but it seems like it would work. I've only needed to do that level of liquor removal on myojins. Whatever he puts on there does nooot come off.

Are you using 100% acetone? No reason that should not dissolve the traditional lacquer used by makers to protect the blade. Give the blade a good soak, then use clean clothes to wipe the blade, avoiding going over the blade with the same area on the cloth. Repeat if necessary.

If using acetone, make sure to wipe with a clean cloth each pass. Otherwise, you just end up just spreading around the lacquer that you're trying to remove

Boiling acetone in a suitably tall container does a great job. Not recommended on a gas stove though. If things go whoomph you’re likely to tip the knife in the ensuing burst of activity.

Acetone should work. It doesn't just wipe off though. It can be stubborn. Let it soak in a bit. I found that higher quality makup remover cotton pads help lift it off better.

I just tried cape cod. No it doesnt work. I will try Flitz.

Yes 100% acetone, apparently it doesnt work. Tried nail polishing removal it doesnt work too.

 

[Heckel7302]

And I'm highly suspect of flitz or any other metal polish being able to remove lacquer

Yes 100% acetone, apparently it doesnt work. Tried nail polishing removal it doesnt work too.

In case it is shellac, alcohol works. So does a splash of ammonia in some water.

Flitz won't work. Ok, so what brand knife are you working on? Ku finish or Migaki?

Next thing to try is vanish stripper. Just don't get it on the handle. Same principle of clean cloth each pass over the blade. If that doesn't work you have a problem.

Or if you know anyone who works in a Chemistry Lab try N-methylpyrollidone. In my experience this will dissolve practically anything synthetic. Or look for a paint stripper that has this in its formulation.

Lacquer thinner.

I removed lacquer from my myojins with acetone but I must say it was more intense than the most brutal workout. Hate that stuff

Acetone almost always work even on the thick silicone kinda thing in my experience. Sometimes you need many (can be 10 plus) passes. Honyakis sometimes come with super thick lacquer. Best is probably old white tee. Like someone else said, use a clean cloth, paper, etc with every pass. I personally don’t think you want or need to use flitz, but won’t harm the knife either.

Silicones yield well to hydrocarbon solvents like mineral spirits (ligroin, petroleum ether, Leichtbenzin). Acetone is usually the best choice, but it is too polar for silicones.

In my experience acetone/nail Polish remover will take off the lacquer. Do you have pictures of what you are trying to take off?

Yes! This is critical. Worked this out quickly my first time.

I call it “silicone kinda thing” but I have no idea what it is lol last time I took chemistry was more 20 years ago…

No worries. I figure I’ll speak on matters in or neighboring on organic chemistry. Thus do I add value to offset my love for the playful.

Hi guys,

Thanks for the suggestions.

Here are photos of the knife with a layer coating the ura side.

Adding with acetone still won’t work.

Trying flitz when it arrives.

 

[OllieOllie]

Tried flitz.

won’t work.

 

[tostadas]

Are you wiping it or just pouring stuff on top?

Looks like a flitz beauty mask

Wipping it with flitz. Doesn’t work.

Any suggestions? Haha

Some sort of hardcore paint stripper?

 

[plantgainz]

Mount Doom lava?

 

[aporigine]

Mount Doom lava?

Only if that’s a Kurosauron

Mount Doom lava?

Last resort. I probably won't be returning, but if I do, I might have that one knife to rule them all.

In case it is shellac, alcohol works. So does a splash of ammonia in some water.

Will try this.

I'll give this a try as well. If alcohol or boiling acetone works, will update.
