A more effective weed and grass killer, according to SFGate, is 1 tablespoon of dish soap, 1 tablespoon of 20 percent vinegar, 1 tablespoon of gin and a quart of water mixed together. This mixture kills the roots as well.
Garden Guide mentions a larger solution that requires one gallon of vinegar and chopped garlic cloves, allowing the mixture to sit in a small bucket for 24 hours. Get rid of the garlic cloves through a cheesecloth and add 1.25 cups of salt to the bucket.
Garden Guides discusses another vinegar solution by mixing it with salt. This solution kills weed and grass, but there is a chance of nothing growing in the sprayed area for the next few months. Bleach also kills grass and weeds directly, and gardeners can plant new items in the area in the next few days.
