Patio moss & weeds in cracks

Use distilled white vinegar as a more environmentally friendly way to get rid of patio moss and weeds growing up through cracks. Just pour the vinegar on the affected areas and let it stay there - do not hose it off - and in a couple of days weeds and moss are dead.

If you want more immediate results boil 1/2 cup of table salt in one quart of water and pour the very hot liquid directly on the weeds and moss.
