Most homeowners do not want weeds in their lawn because it makes their lawn look unattractive. There may also be portions of the lawn where they don't want any grass, such as where they want to set up a swing set for their children. They may just want to put mulch around the swing set. Whatever the reason, you can get rid of grass and weeds with products found in your home.
Pour water in a teakettle until it is almost full. Set the teakettle on the stove and turn the heat setting to high.
Remove the tea kettle once it begins to whistle and pour the contents over the grass and weeds you want to kill. The extremely hot temperatures will cook the roots in the soil and kill the grass and weeds.
Sprinkle salt over the area where you are trying to get rid of the grass and weeds. The salt will also kill grass and weeds, and it will ensure that no grass or weeds grow in that spot in the future.
Pour rubbing alcohol in an empty spray bottle and squirt it over the spot of grass and weeds you want to kill. The rubbing alcohol will dehydrate the grass and weeds so that they wither up and die.
Use straight bleach to kill grass and weeds. Just attach a spray nozzle to the top of the bleach bottle and aim it at the grass and weeds.
