Yeah Rick, it might, but sometimes with these older blades you'll find that what happens is that most of the rust comes off and you reach a point where the blade is pretty clean, then it starts to colour up again and if you're not too much of a fanatic, you can get a reasonable stain job straight out of the pineapple juice without using arsenic. I suspect that what might happen is that the residual arsenic is activated by the juice.

Just remember to brush daily with a soft toothbrush under running water.

Would you try to degrease it before a pineapple juice soak, Alan ?

Or no ?

A. G. Maisey · 27th August 2010, 03:28 AM

Definitely yes, Rick.

This is a standard part of the process.

I usually do it in the kitchen sink with warm water, dishwash liquid and soft toothbrush, then I rinse off and dry thoroughly before putting into the juice.

Rick · 27th August 2010, 03:32 AM

No solvents ?
I have a Sumatran/Bugis blade that I cannot get free of oil; no matter what I do to it, including acetone .
I have used everything ; and still it smells of scented oil !!
If it still smells of oil; then it is not degreased; no ?

Sorry to digress ......

No mate.

If the ferric material is porous the oil penetrates down into the body of the blade. You'll never get rid of the smell.

You could wash a blade off with turps, I suppose, acetone tends to dry a bit too quickly for my liking, but all I ever use is dishwash --- when I think its necessary

I've got blades that I've stripped and stained and oiled with kenongo/cendono, and then I come back 12 months later and they still smell of the oil that was on them before I cleaned them up.

I suggest you ignore the smell. Just give it a scrub with dishwash and go ahead with the job.

Yep, that is just what I did Alan; I was amazed at the persistence of the smell through all that preliminary stuff .

I think David had a go at that blade if I recall .

My response is interpolated:-

Interesting posts.
I have at my disposal (listed in ease of obtainability in NZ):

pineapple syrup (canned pineapple slices in syrup)
YOU CAN FORGET THIS.
WHAT YOU NEED IS PINEAPPLE JUICE.I'M IN AUSTRALIA AND I USE GOLDEN CIRCLE, WHICH USED TO EXPORT TO NZ.GOLDEN CIRCLE IS NOW OWNED BY HIENZ FOODS A US COMPANY, YOU MIGHT LIKE TO RING THEM AND ASK IF PINEAPPLE JUICE IS AVAILABLE IN NZ

malt and white vinegar
CHEAPEST WHITE VINEGAR IS OK.
IF ITS A BIT TOO ACIDIC, WHICH YOU CAN GAUGE BY THE SPEED WITH WHICH IT REMOVES RUST, YOU CAN ADD A BIT OF WATER TO DILUTE IT

cooking tamarind solution
NEVER USED IT ON KERIS
BUT ITS ACIDIC AND WOULD WORK AS WOULD ANY OTHER MILDLY ACIDIC LIQUID
I HAVE USED PINEAPPLE JUICE FOR YEARS AND I LIKE IT BECAUSE IT DOESN'T MATTER HOW LONG YOU LEAVE THE BLADE IN THE J8ICE YOU WILL NEVER DAMAGE IT.

methylated spirits (denatured alcohol)
METHO IS NOT A REAL GOOD DEGREASER
YOU SHOULD ALSO BE ABLE TO BUY MINERAL TURPENTINE (TURPS) ITS PRETTY HARD TO PAINT WITH ENAMELS IF DON'T HAVE TURPS.
BUT AS I'VE ALREADY SAID:- ALL YOU REALLY NEED IS DISHWASH, AND YOU CAN GET THAT ANYWHERE

kerosene
FORGET KERO

isopropyl alcohol (70% solution)
NEVER HEARD OF IT

I feel a potential project coming on. I'll have a look for posts on cleaning and depending on availability of time try and use from the above ingredients to clean up the blade.
Any pointers greatly appreciated.

Iff you realy want to do the job as good as it can get, dont use acetone beter use apolar(non polar) solvents, like hexane, petrolether, toluene and so on. Also you can "cook"or boil the blade in water and let it cool down... afther that lot of dirt wil come out of the pores of the blade. But do reconsider about the state of the blade before you try to do this. Also NaOH (sodium hydroxide) can be used to degrease or break oil or fat like dirt on the blade.

Highly technical Kulbuntet, and highly unnecessary.

I've been doing this now for a very long time, I have never had a failure --- I mean not ever, not even one time --- and all I've ever done is as I've just told it.

I do vary things a bit sometimes, depending on the blade. If its really heavily rusted I use vinegar first until the bulk of the rust is off. This saves money, because vinegar is much cheaper than pineapple juice.Vinegar is a bit quicker than pineapple juice too.

If a blade obviously doesn't have any oil on it, I don't wash it at all.

Cleaning and staining a blade is not rocket science, it takes just a little bit of knowledge and just a little bit of experience to produce a pretty decent job.You don't need to get all technical, things will work out anyway, if you just let them.
