1/2 cup plus 2 tablespoons white distilled vinegar
1 teaspoon castile soap
15-20 drops lemon essential oil

mix all the dry ingredients together in a large bowl

gradually add vinegar a little bit at a time and mix well

You may not need the entire amount of vinegar, so add it a little at a time.

mix in castile soap and lemon essential oil

pack well into two ice cube trays (take your time doing this and make sure they are well compacted)

set ice cube trays out to dry for at least 24 hours in a sunny spot

take tabs out of trays and store in a tight-lidded container
