One of the easiest ways for me to get any boat projects accomplished without the two little monkeys destroying my progress is to make the work fun and including them in the job. Ever since Eben fixed the hoses on the front head the odor in there has diminished but it is still noticeable, especially when it gets daily use from multiple people; what an embarrassment to have a stinky bathroom when you have guests aboard. 
   Before the hoses were fixed I dabbled in a few different air fresheners and absorbers but found that the artificial scents made the odor nauseatingly worse. The solution, and project of the day, Home Made Natural Odor Absorbers. I jumped online and found a few different options, but two struck me as easy to do, cheap, and natural. 
Ingredients we used: 
1/2 cup of Baking Soda
1 Tbs of coffee grind
10 drops of essential oil (scent of your choosing) OPTIONAL
1 Coffee filter
1 Piece of yarn, rope, ribbon
The instructions are very easy. Mix the ingredients together in a bowl, then place the mix into the center of the coffee filter. Gather the edges of the filter, wrap the yarn around the top, creating a bulb. Then hide in whatever spot you wish to absorb odors. (The essential oil is optional, the baking soda and coffee grinds will act like absorbers, the essential oils are for air freshening. We chose to use Eucalyptus essential oil in this batch.) 
The life expectancy of these bulbs is a couple of months. If ever the bulbs feel like they are loosing their kick before that time, just give them a few flicks to mix up in the ingredients inside and they will be good as new.
The girls favorite part about this project was hiding the odor absorbers around the boat. We made 6 of them, I made note of where we hid them, so that I can remember their locations when it is time to make replacements a couple of months from now.

The second recipe I found interesting, but we have not tried it yet, mostly because I am not patient enough to have them sit on my counter for 48hrs while they harden, and because I fear with the moisture in the air here they would take much longer than 48hrs to cure. But here it is, with a link to a blog of someone who has made them.
2 cups Baking Soda
1 cup Distilled Water
6-8 drops Essential Oil
1 silicone muffin tray
Mix oil and water together and slowly mix into the baking soda until you have a thick paste. Divide mixture into muffin mold. Let sit to dry for 24-48hrs until completely dried and solidified. Pop out of mold and place odor absorbers in the bottom of garbage cans, diaper pails, etc. Keep unused ones in an airtight container. See One Good Thing for step by step pics and reviews.

Here’s to staying naturally stink free.
