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.
Start by shutting off the water to the toilet and draining the toilet so that the hard water stains are not covered by water. Make a paste by mixing 1/2 cup of Borax and enough vinegar to form a thick paste. Immediately spread the paste onto the hard water stains in the toilet to cover them.
