How long does it take for 3% hydrogen peroxide to break down completely when exposed to light?

A doctor has provided 1 answer

Hydrogen Peroxide: Hydrogen peroxide's chemical representation is h2o2. It has uses in industry in it's purest form but the product available to most of us over-the-counter is usually only 3% hydrogen peroxide and 97% water. It breaks down quickly when exposed to light so it generally comes in brown bottles that filter out the sun's rays. It is known for its antibacterial qualities.
