I don't recommend bleaching wool, silk, mohair, leather, spandex and non-colorfast colors.
Bleach is corrosive. It can eat erode, or eat away, metal surfaces. Don't use it on copper, stainless steel, aluminum, or other metals. And don't use bleach to get rid of rust, especially on fabric.
You can safely bleach cotton, polyester, nylon, acrylic and rayon. Always avoid bleaching wool, silk, mohair, leather or spandex, even a small percentage. Once you confirm that the clothes you want to wash are made of a bleach-safe fiber, then you check if the color is colorfast to bleach.
Bleach can also brighten and whiten fabrics and help remove stubborn stains. Sodium hypochlorite bleaches (also called chlorine or liquid household bleach) are the more powerful laundry bleaches; they disinfect, as well as clean and whiten. They work on many whites and colorfast washables - but not on wools or silks.
Not everything is bleachable. Remember to check the label. I don't recommend bleaching wool, silk, mohair, leather, spandex and non-colorfast colors.
Protein fibers such as wool and silk will get badly damaged by bleach and should never be discharged. These fibers are weak to the effects of bleach and get dissolved. Cellulose fabric like cotton, linen, hemp, and rayon can be bleached to change their color. They can take bleach with minimal damage.
When rubber is exposed to bleach solutions, it can experience a number of different types of failures. The most common type of failure is cracking and weakening of the rubber due to the oxidation caused by the hypochlorite present in the solution.
› Chlorine bleach is a very aggressive chemical, it can and will corrode stainless steel. Remember that stainless steel is primarily steel, chromium and nickel. Chemicals can discolour these materials if care is not taken. Certain acids etc can also cause problems.
Bleach left behind on surfaces after cleaning, even when dried, can still be toxic.
While bleach can effectively clean grout and tiles, its harsh chemicals can also cause damage over time. Additionally, if left on the tiles for too long, bleach can cause stains and discoloration.
Stainless steel, iron, copper, nickel Mixing with bleach releases oxygen in a closed system (e.g., piping, equipment) which can lead to pressure build-up and rupture. Bleach will corrode metal including metal wastewater pipes.
Bleach and ammonia produce a toxic gas called chloramine that can cause chest pain and shortness of breath. Ammonia can be found in some glass and window cleaners, dish detergents, drain cleaners, and urine (use caution when cleaning litter boxes and diaper pails). Bleach and rubbing alcohol create chloroform.
Bleach has a corrosive nature and should be kept in a container made of high-density polythene (HDPE) plastic. Such a container will conserve the chemical properties of bleach and maintain its efficiency for a longer time.
Solution dyed fibers, including acrylic, nylon, polyethylene, and polypropylene, and high-energy polyester exhibit strong colorfastness when exposed to bleach. Polyurethane-based fabrics can also be treated with a finish that enables them to withstand both bleach and high concentrations of rubbing alcohol.
Bleach is a powerful chemical that can degrade certain types of plastics, particularly those that are not designed to withstand harsh chemicals. When exposed to bleach, these plastics may become brittle, crack, or even release harmful chemicals into the food or beverages consumed by them.
Bleach corrodes many metals. It should never be used on stainless steel, aluminum, copper, brass, marble, or granite. Bleach is neutralized by dirt and other organic material, so it isn't very effective when used on a surface that hasn't been cleaned.
It is not advisable to use strong commercial bleach to clean silicone. These can be harsh chemicals and may damage your silicone's properties and deteriorate its quality.
Harsh chemicals or cleaners not specifically formulated for glass surfaces can damage the windows or leave behind stubborn residues, compromising their appearance and longevity. Harsh chemicals such as ammonia or bleach can corrode or etch the glass, leading to permanent damage.
Do not use tyre dressings with bleach because they may make your tyres look weary and grey and can stain your wheels.
If you do have plain white polyester linens, bleach is fine to use in small amounts. If there's a very stubborn, dark stain on a white tablecloth or napkin, you may want to directly apply a diluted bleach mixture on the stain and leave it on for a few minutes before tossing it in a washing machine.
Rinse the area with cold water to remove any excess bleach. Create a thick paste by mixing together some baking soda and water. Spread this over the stain evenly. Leave to dry and then brush off gently – you may want to use an old toothbrush.
It can be stored for about 6 months at temperatures between 50 and 70 degrees Fahrenheit. After this time, bleach will be begin to degrade at a rate of 20% each year until totally degraded to salt and water.
