ElI5: If soap +water or rubbing alcohol can be used to clean a car window to place a sticker, why can’t Hydrogen peroxide be used ?

Hydrogen peroixide is an antibacterial. Alcohol os a solvent that cleans the glass. Soap (a drop mizxed with water) allows the sticker to slide into position before you squeeze it out from underneath.
Who says you can’t? Make it happen, amigo and determine for yourself which one works best.
Soapy water acts as a lubricant allowing you to place the decal exactly without out sticking down too quickly in the wrong location. Once placed you squeegee out most of the water and any air bubbles. When the water evaporates full adhesion occurs.
Alcohol is a fast evaporating solvent. It’s good for cleaning a surface like glass of any impurities. Because it evaporates so quickly and also might weaken certain adhesives, it’s probably not ideal for setting stickers.
Hydrogen peroxide is an oxidizer composed of water with an extra oxygen ion. It reacts primarily with organic substances. It does not evaporate fast so it might be suitable as a decal set but I would be concerned about the oxidizing properties potentially affecting colors or adhesives.
You probably can, but be careful not to spill any peroxide. It can bleach your clothes or certain fabrics.
Soap molecules have two ends: one end that sticks to water molecules, and one end that sticks to oils and dirt and such. So when you clean a window with soap, the soap molecules stick to the oil and dirt on the window, and then they stick to the water that rinses them away, taking the dirt/oil with it.
For rubbing alcohol, it actually dissolves oil residue, which is why you can also use it to clean sticker residue off a window (glue molecules and oil molecules are chemically similar in many cases).
Hydrogen peroxide works by causing a chemical reaction with the things it touches. However, it turns out that the reactions it causes are not really that useful for cleaning a window. We don’t use it because it doesn’t work the way we need it to.
