Can I decoffee my coffee grinder?

[Drama Llama]

Gonna make some poppy seed roll.  Directions say to ground up a pound of seeds in a grinder.  

I have two, but one is surely nut contaminated.  So that’s out.  My other one had only been used for coffee.  Can I get rid of the coffee somehow so it won’t contaminate the taste? And vice verse?  Turn it back to coffee? 

Or do I just tell my kids they need to ground a pound of seeds with a mortar and pestle?

Honestly, as someone who hates coffee I can still taste it even when they have been throughly cleaned   Do you have a blender or food processor?  You can use those in a pinch to grind.

You can try grinding bread in it. But I think it might still smell a little like coffee.

I have a vitamix.  Can I use that?

I have used my vitamix for this.  Just watch carefully as you can go from grind to paste quickly in it.

I think I want paste.

Yes, use your vitamix

Coffee oil is terribly persistent. I would not even make the attempt--a Vitamix or food processor is a better bet.

The vitamix should work fine! I have actually used mine to grind coffee in a pinch. LOL (we forgot that we didn't have a coffee grinder at the cabin and brought whole bean coffee on vacation.)

Or even a mortar and pestle if you have strong hands and one that doesn't have too porous of a texture (the seeds may just get stuck).

I clean my spice grinder by wiping it out and then running dry rice through it to clean it. Then I use liquid dishwash soap, a tiny bit of water and an old toothbrush to scrub the remaining oils off. I use my kitchen sprayer to make sure to dislodge any grounds from under the blade. Then I dry it, run rice through it again and wash it again. It turns out sparkly like it is brand new and no odors! Mine is all stainless steel, so if there is any other material it may not work as well. 

I have also used my immersion blender to grind somethings that start of course, but it wouldn't make a paste.

I have a designated grinder that I only use for spices - the oils in coffee are amazingly persistent. I also do use a mortar and pestle.

However, you can try getting the oil out of the grinder in the following fashion. I am assuming an electric grinder. Instructions may need to be modified for a manual one. First, wipe it out thoroughly with a damp cloth and then a dry one. Set to dry. Once it's fully dry, take some slightly stale bread, break it up, grind it into crumbs in your grinder. Repeat this step a couple of times, then do it again with some grains of uncooked white rice. Once the rice has been ground up twice or three times it should be more or less good to go.

Be sure to wash the top as well!

The poppy seeds won't contaminate it backwards, so no worries there.

It may be less effort to go to the store and buy a new grinder.
