Had to clean a ceramic teapot they had been left with used moist tea leaves in it.

Soaked and most of the yuck wiped away.

Could not get the bottlebrush everywhere inside the spout behind the leaf filter.

Hydrogen peroxide left soaking in the lower spout for 24 hours removed 98% of the remaining stain.

Odourless.

#Alcohol or #HydrogenPeroxide? When to Use

Both #rubbingalcohol and hydrogen #peroxide kill #germs, making them tempting to use on a cut or #wound. But with those germs, they’re also killing good #bacteria and irritating your #skin.

This seems an excellent result:

"Herein, we report the efficient photocatalytic production of hydrogen peroxide... Significant photocatalytic hydrogen peroxide generation occurs under ambient conditions at an unprecedented rate of 23.7 mmol g–1 h–1 and an apparent quantum efficiency of 11.3% at 450 nm."

H2O2 can be a significant help in certain difficult fossil fuel substitution cases. And we use 6+ million tons/year.

Efficient photocatalytic production of hydrogen peroxide using dispersible and photoactive porous polymers - Nature Communications

Current industrial production of hydrogen peroxide suffers from hefty energy penalties and toxic byproducts. Here, the authors report efficient photocatalytic production of hydrogen peroxide by protonation-induced dispersible porous polymers with good charge-carrier transport properties.

Whitening the case using hydrogen peroxide and an UV lamp for fingernails. I'm pleased with the result so far. Sadly, the lamp is a bit too short, so I have to repeat from the other side.

The glow stick consists of a transparent #plastic cylinder filled with phenyl oxalate #ester and a glass tube with hydrogen peroxide inside. When the stick is broken, the two substances merge and react with each other. A #chemiluminescence reaction takes place. This ester is #toxic to humans.

A photocatalyst that can produce hydrogen peroxide from oxygen and water

Hydrogen peroxide (H2O2) is a colorless liquid compound with strong oxidizing properties that can have numerous industrial and medical applications. This compound is generally synthesized through the anthraquinone process, through which the compound anthraquinone combined with palladium-based materials catalyzes the oxidation of dihydrogen (H2) to H2O2 with O2 from air.

A safe synthesis of hydrogen peroxide inspired by nature

Hydrogen peroxide is a ubiquitous chemical found in most homes and used in everything from dying hair to treating wounds. It is also an invaluable agent for many industries from food, textiles, and even in semiconductor production.
