Definitions

• Liquid all-purpose detergents for household and commercial use have taken their place in the past decade because they are easy and straightforward to use.
• the agents are usually marketed as preferably aqueous concentrates. They can be applied diluted or undiluted to a damp, absorbent cloth of any nature or a sponge, with which the hard surfaces made of metal, lacquered wood, plastic, ceramic products such as porcelain, tiles, tiles and the like can be wiped off and thereby dust, greasy dirt and stains are removed.
