So, I regularly hear about how cakes of shaving soap last for weeks or months. But my soap cakes are lasting about a week and a half, I'm wondering if perhaps something is wrong with my technique? So let me describe what I do with them.
I use classicshaving's regular cakes of soap. When I run low on soap in my mug, I drop a cake in and microwave it for 40 seconds to make it fit perfectly in the mug. I then let it solidify for a few hours before I try to use it. I run my water as hot as a I can, then I hold my brush (Vulfix's bottom-of-the-line boar brush) under the water for a few seconds. Then I fill the mug with hot water and submerge the brush in it. I then take a quick shower (usually about 5 minutes on a weekday) then I get out. I drain almost all the water out (I need to keep a little in, because the brush doesn't hold much water, and I usually need to add more water once or twice while shaving because the lather gets pasty) then I just put the brush in, with moderate downward force, then swirl it back and forth in a circular motion until there's a good lather in the brush. At least, I think it's a good later. I work it until there's no bubbles and I can spread it on my face with a slightly creamy feeling instead of a liquid one, and I can't see my skin underneath for about 10 minutes. So that's what I do. Why is the soap going so quickly?
