A toilet brush is a tool for cleaning a toilet bowl. Generally the toilet brush is used with toilet cleaner or bleach. The toilet brush can be used to clean the upper area of the toilet, around the bowl. [1] However, it cannot be used to clean very far into the toilet's U-bend and should absolutely not be used to clean the toilet seat.
Toilet cleaner is sprayed around the rim and into the bowl of the toilet prior to the use of the toilet brush. The toilet brush is used to scrub the toilet, removing stubborn stains and biological debris. In recent times, automatic toilet bowl cleaners that clip onto the rim of the toilet and clean with every flush have also become prevalent ...
The NIOSH Power Tools Database contains sound power levels, sound pressure levels, and vibrations data for a variety of common power tools that have been tested by researchers. Data are collected for both the unloaded and loaded use of power tools. The database was created by the National Institute for Occupational Safety and Health (NIOSH).
In 2008, a disinfectant was added to "kill 99.9% of bacteria flush after flush" in an apparent response to competitive pressures; Ty-D-Bol has claimed to "kill 99.9% of toilet bowl germs with every flush" since 1994 and crystal bowl cleaners have made claims to "kill millions of germs" since Sani-Flush's 1911 introduction.
Sani-Flush was an American brand of crystal toilet bowl cleaner formerly produced by Reckitt Benckiser.Its main ingredient was sodium bisulfate; it also contained sodium carbonate as well as sodium lauryl sulfate, talc, sodium chloride, fragrance and dye.
Initially, Vanish sold their product in a white 22-ounce showing the bowl cleaner coming from the bottom of the "I". After World War II, Vanish advertising started to show a woman pouring the product into a toilet bowl, and then a hand, obviously female, pouring powder into a toilet bowl. Dunaway won on appeal. [3]
Mains hum, electric hum, cycle hum, or power line hum is a sound associated with alternating current which is twice the frequency of the mains electricity. The fundamental frequency of this sound is usually double that of fundamental 50/60 Hz , i.e., 100/120 Hz, depending on the local power-line frequency .
The result is a wide-bandwidth high-power source. Conventional diodes can be used in breakdown. The avalanche breakdown also has multistate noise. The noise output power randomly switches among several output levels. Multistate noise looks somewhat like flicker ( ) noise. The effect is process dependent, but it can be minimized.
