30 ways you have never considered using wood ash

If you’ve got a fireplace or fire pit full of wood ashes and would like to find a more useful purpose for them than simply tossing them in the trash, read on! We’ve come across 30 great uses for ash you may never have considered:

1. Make lye water. To do this, boil 2 or 3 spoons of clean white or gray fluffy ash with water and then sift it through a coffee filter. Lye water is a terrific cleaning agent and sanitizer for everything from clothes, to floors, windows, silverware, plates, and even rust in marble. You can also make lye by adding the ash in a cheesecloth.

SAFETY NOTE: This is a simple version of this process, but for safety’s sake, it’s advised you obtain more information before making lye water as it is potentially dangerous and lye is caustic.
In a bucket with holes on its base, add the cheesecloth and then ash, then hang it up. Add the water with another clean bucket underneath to collect the lye. The lye should have a brownish color, so remove the bucket when clean water starts to sift through. Test the lye by placing a fresh egg in the liquid. If the egg floats, the lye is good to go, if not, repeat the process.

2. A simple paste of ash and water is an effective way to remove stains from furniture.

Apply sifted ash powder generously to cover spills or stains on asphalt, sidewalks, drives, garage or shop floors and allow a little time to absorb (you will see it darken as it works). Scrub the ashes with a broom to loosen clumps and work it into the surface, and stir and spread the ash over the area until all of the ash has darkened and stops absorbing. Sweep up the spent ash, apply more and repeat as necessary until ash powder stops absorbing. Ash powder can be mixed or selected by color and be lightly applied and swept on once the spill is gone to hide and blend away any remaining discoloration and restore the look and dull luster of the affected surface making old, deep or tough stains invisible. If desired detergents, degreasers, or other agents can be applied and worked in to break up stubborn and soaked in residue or discoloration, then absorbed with ash. Spent ash can be placed back into the fire and used again when the absorbed materials are burned or evaporated out. (Caution should be taken not to breathe the fumes, and ash laden with flammables will flash when burned). Keeping buckets of sifted ash in the garage or shop ready to go is an effective way to quickly clean up fresh spills before they stain, soak into, or damage concrete, as petroleum products and other chemical spills will break it down if left on or soak in, and ash will eliminate slip hazards from spills as well.
