When you're putting your hands through some serious dirty work. It takes a strong soap to get the garbage off. In this area, there aren't too many better than Lava. Lava is a heavy duty soap that was specifically made for hard workers. The soap gets its name from the active ingrediant pumice, which happens to be a volcanic rock. The soap feels much rougher than your average hand soap, you will immediately notice the difference.
The soap is said to be easy on hands but tough on dirt, grease, paint, ink, and many other materials. In my line of work, I sometimes deal with paint, oil, and grease, only to name a few. When I use to get done and jump into the shower, I would notice that the regular bars of soap did very little with getting the stuff off my hands. I began to use Lava, and after washing my hands with it for a few short minutes. The material would rub right off. The soap has a grit-like feel and you could see the things peeling off.
The bar normally lasts for a very long time, because it doesn't take much to get the job done. Also in my case, I don't do these things too often. The soap comes in two forms that I know off; as the bar and in a liquid bottle. The bar now has hand moisturizers, in which it didn't years ago. The only issue I can think of is using it on the face. Besides the fact of it being a hand soap, I just don't trust it on my face, and I'll never take that chance.
The soap really doesn't have much of a smell that is worth noting, but it's not meant to be a beauty product anyway. I recommend Lava to those who are doing very dirty work like car or boiler mechanic, gardening, or dealing with tar. I really like the soap and it's among my favorites for these types of jobs. But recently, Gojo Hand Soap has proven to be the better of the two, and I would recommend that before this.
