Electrical transmission towers support wires that carry electricity from power plants to homes. Electric current is electric charge in motion. It can take the form of a sudden discharge of static electricity, such as a lightning bolt or a spark between your finger and a ground light switch plate.
To clean stubborn stains from your toilet bowl, first if you have a wet/dry vacuum, suck out all the water so you have a virtually liquid free bowl. Then, pour in hydrogen peroxide. It will get rid of all stains and lime. I would suggest using 1/2 a bottle for each cleaning. You might need more or less.
Turn the water supply back on and flush once the bowl is clean. Trisodium phosphate, a heavy-duty cleaning powder that can be found at your local home improvement store, is another great product that can be used to remove tough toilet stains.
