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.
Let borax sit for a half hour after scrubbing, and when stains are removed, turn the water supply on and flush. To clean a toilet with bleach, measure a half cup of dry bleach powder and allow it to sit in the bowl for up to two hours. Flush once you see that stains are removed. As a last resort, use a pumice stone and a toothbrush to get rid of extreme toilet stains.
