Any body use these.

If I use these camphor blocks as a rust preventive in my tool boxes and cabinets, how many do I need to use. 1 per drawer or 1 per box/cabinet. What is the area coverage of a block.

How does Camphor work as a rust preventative?
I have desiccant bags in my drawers.

Don't know why it works, but it does. But the blocks evaporate and need replacing periodically. I used to find them at the nearby drugstore, haven't seen any lately....

When I was a kid, all of the really old men wore blocks of camphor in a woolen sock tied around there neck to ward off "the grippe". You could smell the old buggers coming from a half mile away if the wind was right.

We always put just one in the bottom drawer of each box. Pierce the wrapper of the one block with a sharp tool, such as a pocket knife or a scribe. Don't unwrap it anymore than that. The camphor works itself upwards, even into the upper compartment of most tool chests, such as Kennedy or Gerstner.

I have heard of this being an old-timey thing before for keeping your tools rust free. Nice to hear some first-hand accounts that it works. How long does a block last before it evaporates away? Do the wrapped ones keep for a long time?

I live in Arkansas, how many do you need to do a whole room. God do I hate the temp swings in the spring.

Uses

Modern uses include camphor as a plasticizer for nitrocellulose (see Celluloid), as a moth repellent, as an antimicrobial substance, in embalming, and in fireworks. Solid camphor releases fumes that form a rust-preventative coating, and is therefore stored in tool chests to protect tools against rust.[9]

Some folk remedies state camphor will deter snakes and other reptiles due to its strong odor. Similarly, camphor is believed to be toxic to insects and is thus sometimes used as a repellent.[10] Camphor crystals are sometimes used to prevent damage to insect collections by other small insects. They are also used as a cough suppressant.
Interesting, never heard of it before now...
It would likely be good in my gun safe too...

If camphor works to keep tools from rusting that don't get used that often then I am going to put some in my underwear!:cool:

Aren't they the same as common "moth balls"? I've heard of using them to prevent rust, but never tried it. Air conditioning seem to work well in my case as all my stuff is in the BSMT. Bob.

Camphor has been used as a moth repellant and may have been made into math balls at some time in the distant past. The common moth ball is naphthalene-somethingorother and the smell is different from that of camphor, more pervasive and very unpleasant, IMO.

I'd be leery of the "camphor" products hawked on Amazon: one purchaser commented that he was shipped incense (that may or may not have been infused with camphor).

And here's a description of the "camphor" product being sold on the Walmart online marketplace:

"Camphor is well known for its ability to help restore spiritual vigor and renew the spirit- Some also believe it can aid with psychic abilities and prophetic dreams- Many herbalists also use it as a home remedy for cough and congestion."

Mothballs made of naphthalene have been illegal in the UK since (I think) 2008 because it's bad for us.

Camphor sublimates and deposits a thin coating over the surface of the metal which acts as a rust preventer.

It also keeps the mice out of the tool boxes. I started using it about 2 years ago because I was finding mouse nests in little-used drawers. None since.

Camphor works very well but it's a little smelly.

OTH there is this stuff:

Look up "VPCI" (vapor phase corrosion inhibitor) emitter.

If VPCI (or camphor) is to be effective it has to work in an enclosed volume like a lidded tool chest or in packaging of some kind. The goodies escape from a vented locker or closet. The vapor evolves slowly. If you access the protected tools frequently the vapor protection is lost every time you open the chest and the vapor has to re-establish itself.

"moth balls" from grade nine science circa 1965 were paradichloralbenzene

That's "paradichlorobenzene", I think.

Here's what I got. It's 100% camphor:

Enquired at our local drugstore, small town (3000 people) and they still sell them, $2.50 each though.

The ones that I just pierced with a sharp point would last almost a year. The ones not opened at all would be gone in less than two years.
