Save Your Coffee Grounds! Turn Them in to Gardener's Soap

354,134 Views
Instead of throwing away my used coffee grounds, I saved them to make a gardener's soap. This recipe scrubs away dirt while the shea butter softens your skin.
Time: 1 Hours Cost: $10 Difficulty: Easy

I used to put my leftover grounds on my rose bush, but I don't have a rose bush any more. I have to be careful dumping them outside because I have free range chickens. I don't need a bunch of caffeinated chickens running around.

Start by melting your soap base. I used 8 ounces of melt and pour soap. I microwave it for 30 seconds at 80 percent power and stir. Just be careful that it doesn't start to boil.

You want to let it cool until a scum forms on the top. Meanwhile, mix .5 tablespoon bentonite clay with an equal part distilled water to make a paste.

Once the soap cools, add the clay and water mixture, 1 tablespoon cornmeal, .5 tablespoons dried coffee grounds, .5 tablespoon shea butter, and 1 teaspoon of orange or lemon essential oil.

    • I read that coffee grounds help clean out your drains???Ceal Whalen April 28, 2016
    • Just remember your kitchen sink is not a garabage disposal.
    • I use coffee grounds twice weekly on my hands to get rid of dead cells and exfoliate my skin! I just take some lotion soap in my hands, add coffee grounds and rub on my hands for a few minutes. Then I rinse and wash again with just the lotion soap. Feels so good and helps immensely with my dry hands!
    • The amount of coffee grounds in one bar of soap, let alone from one hand washing, is not going to effect the drains one way or another.
    • Agreed Mikkigirl. I'm sure if large amounts of coffee grinds were dumped in your drain it would clog the drain over time, however when using a small amount of coffee grinds like what is present in this soap or scooped into the palm of your hand during a twice a week exfoliative handwashing, it shouldn't harm the drains particularly when used with soap. I would be more concerned about the excess Shea Butter going down my drain however, I use bleach and other cleansers to clean my sinks, toilets and bathtub/shower and I'm sure that breaks down coffee, Shea Butter and the like as well. I go to coffee shops and ask for their cappuccino coffee grinds as those are very finely ground and come in handy compacted rounds with most of the water pressed out of it. When I make homemade body, hand and face scrubs I only use the cappuccino grinds. They are very small but still exfoliate very well and I still get the benefit of the caffeine for my skin. They also work better in my soil as they are dryer and more finely ground. (^_^)
    • The biggest reason they don't want coffee grounds going down your drain... in areas where water goes into the ocean, streams and lakes, it polutes the water. They claim they have found high levels of caffeine in some of the lakes, streams and even areas of the ocean. I say, find a way to remove it and make a new coffee drink. LOL!
    • Seriously, by the time coffee goes through the process of getting to the ocean there's not much caffeine left. If you put the used grains down the drain, use a vinegar and baking soda cleaner regularly. It will dissolve any "clumping" and run hot water as a follow up. Where I would be concerned in depositing anything down your drains without using a garbage disposal unit is if you have cesspools. You stand the risk of clogging your tanks.

    • @Valerie I believe it said 5 TBLSPS dried coffee grounds above, I think the link is a missprint
    • 5 T coffee - the 1/2 T is the amount of bentonite clay.
    • Hmm...the recipe above does state .5T of coffee grinds

    Sounds wonderful - but where do you buy all those weird ingredients? I live in the middle of nowhere - but occasionally get to a craft store - thanks.

      @Texasgranny They are all linked in the post. Amazon has most of the ingredients.

    Are you sure it's only .5 (1/2) tablespoon of the bentonite clay, water, and coffee grounds? I made this recipe yesterday and only got 2 1/2 bars of soap; plus they have very little color. Definitely not a solid dark shade like yours!! Thank you

    Could you make these from bars of soap instead of the soap base?

    I think these measurements are incorrect 1/2 tsp .5 wouldn't even be enough grounds for one bar of soap

    Could you please check the queries in your comments re the measurements for this recipe - thank you.

    I save slivers of bar soap, add a little water at a time, microwave for 45 seconds at a time (I'm working with about 2 cups soap slivers) until melty and thick. Then I pour it into a mold and let harden in a cool dry cabinet with a tray of clean cat litter to speed the drying process. I don't see any reason you couldn't recycle the coffee grounds along with the soap slivers for the potting shed soap! Also, if you work a little soap up under your nails before you start digging, it'll be a lot easier to have clean hands when you're done if you are like me and don't like to wear gloves.
