Seems to be to "go to" solution to prevent rust from forming on tools. I put these blocks in my toolbox box and still waiting to see how it works. It does have an odor, but it's not unpleasant.

I put these in my safe to prevent rust on my firearms. I also put a piece in the drawers of my tool boxes. These work great for that!! No more rusting tools. They will slowly dissolve so they need to be replaced every few months (3-6) but they're cheap so not a big deal. Much cheaper then an expensive tool rusting up! An added bonus, when I open my safe, I get a slight whiff of Camphor and it's a pleasant smell.

I heat peanut oil and add a block of camphor to the hot oil then use the cooled mix on my horses hooves as a conditioner. Works well.

I use camphor to make a paste for poison ivy, or in my case, poison sumac. There used to be a liquid you could use called Ziradryl. It was great. Put it on once or twice and you were healed. It worked well so of course they stopped making it. I had an old bottle and figured out a similar "recipe" that I use on myself whenever I get into the sumac. I have a bunch in my garden so I will be using a lot of the mixture and camphor is one of the ingredients. I will be cleaning out all the sumac so wish me luck.

I used it in my mop water also to help purify my home and it did it help with the smell and size is real good plus it performance good.
