Here are two versions. Let me know which one works best for you.

1 gallon full strength vinegar
1 cup orange oil
1 teaspoon Dr. Bronner’s Peppermint Soap or other mild soap

or

1 gallon full strength vinegar
1 cup orange oil
1 cup molasses
1 teaspoon Dr. Bronner’s Peppermint Soap or other mild soap  I use Bio Wash.

Vinegar strengths vary. 5% is regular vinegar. 10% is pickling vinegar. 20% is the strongest you should ever use and it is dangerous and needs to be handled carefully. Avoid contact with skin and breathing the fumes. Be sure to keep the mix well shaken while spraying. Avoid products that are made from glacial acetic acid.
