Sodium hypochlorite solution, 3–6%, (common household bleach) is typically diluted for safe use when disinfecting surfaces and when used to treat drinking water. [31] [32] A weak solution of 2% household bleach in warm water is typical for sanitizing smooth surfaces before the brewing of beer or wine. [citation needed]
A 12% solution is widely used in waterworks for the chlorination of water, and a 15% solution is more commonly [36] used for disinfection of wastewater in treatment plants. Sodium hypochlorite can also be used for point-of-use disinfection of drinking water, [ 37 ] taking 0.2–2 mg of sodium hypochlorite per liter of water.
When diluting a product, one must be aware that the volume of the diluted solution may not be the sum of the volumes of product and water. For example, one ml of 5.25 wt% NaClO bleach added to ten liters of water, will yield a NaClO concentration of about 5.76 mg/L, and 5.48 mg/L of free chlorine. [24]
Also, use diluted bleach wisely. For small spots, dabbing with a cotton swab of diluted bleach might be a simple and powerful solution. Last, air dry your white clothing outside, if possible.

In 1928, a study found that airborne microorganisms could be killed using mists of dilute bleach. [18] An air disinfectant must be dispersed either as an aerosol or vapour at a sufficient concentration in the air to cause the number of viable infectious microorganisms to be significantly reduced.
No green thumb? No problem. We put together a guide to 10 plants that are hard to kill, including cast-iron plant, ZZ plant, and pothos.
Bonsai enthusiasts use undiluted lime sulfur to bleach, sterilize, and preserve deadwood on bonsai trees while giving an aged look. [5] Rather than spraying the entire tree, as with the pesticidal usage, lime sulfur is painted directly onto the exposed deadwood, and is often colored with a small amount of dark paint to make it look more natural.
