The table shows how the two systems rate high-brightness papers, but there is no simple way to convert between the two systems because the test methods are so different. [4] The ISO rating is higher and can be over 100. This is because contemporary white paper incorporates fluorescent whitening agents (FWA). Because the ISO standard only ...
Purposes of cleaning agents include health, beauty, removing offensive odors, and avoiding the spread of dirt and contaminants to oneself and others. Some cleaning agents can kill bacteria (e.g. door handle bacteria, as well as bacteria on worktops and other metallic surfaces) and clean at the same time. Others, called degreasers, contain ...
Active oxygen bleaching agents include sodium perborate, sodium percarbonate, sodium perphosphate, sodium persulfate, and urea peroxide. These compounds release hydrogen peroxide during the wash cycle, but the release of hydrogen peroxide is low when these compounds are used in temperatures below 45 °C (113 °F).
Let it set for a few minutes and then wipe clean with a lint-free cloth or paper towel. One note: Don’t use Windex on your wood furniture, as the ammonia may damage it. Clean Light Fixtures
Paper chemicals designate a group of chemicals that are used for paper manufacturing, or modify the properties of paper. These chemicals can be used to alter the paper in many ways, including changing its color and brightness, or by increasing its strength and resistance to water. [1] The chemicals can be defined on basis of their usage in the ...
Ozone gas can also be used for retrobrighting, as long as an ozone generator, a suitable container of sufficient size and a source of UV are available, but can take longer than other methods. [ 8 ] A simpler but slower process involving merely exposure of the yellowed plastic to bright sunlight has been described, variously called 'Sunbrighting ...
I always have a jug of white distilled vinegar that I keep under the sink to use to brighten laundry, beat stains with the help of baking soda, spot remove on carpets, clean veggies, and many ...
Sulfur dioxide is one of the few common acidic yet reducing gases. It turns moist litmus pink (being acidic), then white (due to its bleaching effect). It may be identified by bubbling it through a dichromate solution, turning the solution from orange to green (Cr 3+ (aq)). It can also reduce ferric ions to ferrous. [22]
