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.
, I have owned a residential cleaning and home management business for 20 years. Lime-Away toilet bowl cleaner (not spray cleaner, which is a different product) is EXCELLENT at getting out really tough stains in toilets. I have been successful cleaning toilets brown with water stains decades old with this product. It may take a few uses, allowing it to sit on the toilet bowl for several minutes at a time, but it will get it clean.
