How do you clean warangka interior?

[Neo]

First the cold blue, and now the brushes ... I really need to pay a visit to a gun store. Thanks for the pointers, I will really make the effort. A friend just told me earlier today that lapangan tembak in Senayan may have some gun supplies.

Anyway, just one last question. At first I tried not to ask this because I felt it sounded too paranoid, but then I thought there's some sense to it. Let's say you just had a mranggi make you a NEW wrongko and you saw some sweat dropping into the sheath. It is quite a likely scenario, considering how hot and humid Indonesia is these days. Now, salt and iron is a very bad combo ... bad enough that I couldn't resist asking this question

Is it okay to just quickly rinse the wrongko interior with some liquid to wash away the salt? Say, 95% alcohol? mineral oil? Will that damage the wrongko?

I would think that scraping or wire brushing would be better; at least by this point the salt is dry and can be scraped away .
Wetting it would most likely worsen the problem .

I'm no chemist but I don't believe Alchohol will dissolve salt unless diluted with water .

OK, it's clear. I will visit a gun store, even if it's thousand miles away!!
Many thanks, guys!!

"Bottle brushes", "tube brushes", "pipe brushes", "bore brushes" and "pipe fitting brushes" are available in assorted diameters, often sold as a set containing several brushes varying in diameter from 1/4"-3/4" with 4" long bristle section and about 12" length O/A. Usually available with brass or steel bristles, they can be found at many auto repair and hardware stores. The brass bristles easily bend out of shape and stay that way; they haven't been as useful to me as steel ones. Be aware, in areas/countries which are not particularly "firearm friendly", the words "bore" and "calibre" may set off red flags and cause all sorts of life-disrupting problems you never imagined you could have. Don't mention .17 or .22 calibre, any decimal millimetres, or "gun cleaning brushes" and you'll likely be safe. I've had success with using broken coping saw blades (with teeth reversed, like a 'Japanese pull saw') to pull out tiny bits of wood stuck inside things; for cleaning out the bottom of a pendok, it might help to stick it (the broken coping saw blade) into the end of a 3/8" diameter metal tube (such as the grease tubes sometimes found on large industrial electric motors) and squeeze/flatten that around the saw blade to make an extension. If one is able to somehow gain access to the scrap bins and "short end racks" usually found behind machine shops, auto wreckers, electric motor repair shops, rail yards, the trades department at the local college, etc. these can be a bonanza from far beyond the wildest dreams of the do-it-yourself enthusiast, with all kinds of materials for projects you'd never imagined until you found the stuff to make them.
