Evening all. I’m making a console table, mostly Cherry but with some Walnut for accent. I have noticed my hands pick up a bit of a dark stain, mainly on my fingers and a bit on the palms. I first noticed this when I built my cutting board (Maple and Walnut) and the walnut sawdust stained the white maple. I assume I’m not gonna grow a third eye or anything like that???? Any thoughts? Thanks.

Happens to me too. Walnut and white oak get them black. Hard to get it off too. I believe it is the tannins (sp?) in the wood.

Same here. I’m currently doing some arts and crafts furniture in walnut…constantly looks like I have dirty hands.

Every day when I go to my day job in corporate America I feel like Edward Norton in Fight Club when he shows up to work all beat up.

It usually wears off my hands after a couple of days out of the shop.

Lemon juice, guys, or vinegar. Or, my secret tip, Barkeeper’s Friend. The acid takes out the tannins.

The higher the moisture content the worse it gets. I am using some at about 6% and no problem but just pick up a freshly dropped waltnut with the outter shell just darking and hands get really black. Thanks shampeon, I
ll heed your advice next season. As we have 5 large trees on our property to contend with their production of nuts each fall; and my hands look like farret feet.

Tannin + iron = blackish-purple stains.

Walnut is very high in tannin and many woodworking tools have iron parts. Doing work with walnut almost inevitably causes purple stains on the hands. I suspect there’s iron content in people’s sweat too.

There was another discussion about this a while back:
