When I make soap without any colorants or fragrance is when I notice this little black dust bits and crap on the side of the bars. I wash the molds and dry them before pouring and it still happens. Picture sucks, I apologize. It's more noticeable in person. If you look right above the glare on the soap you can see the bits. It's an easy solve just planing the sides but I'm wondering if anyone runs in to "stuff" on the sides of there white bars or if I need to do a better job. Its driving me insane because how many dirty bars have I sold and not noticed because of the colorant.
