  2. Chemical drain cleaners - Wikipedia

    en.wikipedia.org/wiki/Chemical_drain_cleaners

    Acidic drain cleaners usually contain sulfuric acid at high concentrations. [1] It can dissolve cellulose, proteins like hair, and fats via acid hydrolysis. While there are many methods for unclogging drains, one of the most effective solutions is using hydrochloric acid (HCl), a powerful chemical cleaner. [2]

    en.wikipedia.org/wiki/Cleaning_agent

    Hydrochloric acid is a common mineral acid typically used for concrete. Vinegar can also be used to clean hard surfaces and remove calcium deposits. Sulphuric acid is used in acidic drain cleaners to unblock clogged pipes by dissolving organic materials, like greases, proteins, and even carbohydrate -containing substances such as toilet tissue.

  4. Pickling (metal) - Wikipedia

    en.wikipedia.org/wiki/Pickling_(metal)

    Strong acids, such as hydrochloric acid and sulfuric acid are common, but different applications use various other acids. Also alkaline solutions can be used for cleaning metal surfaces. Solutions usually also contain additives such as wetting agents and corrosion inhibitors. Pickling is sometimes called acid cleaning if descaling is not needed ...

    en.wikipedia.org/wiki/Hydrochloric_acid

    Hydrochloric acid is used for a large number of small-scale applications, such as leather processing, household cleaning, [35] and building construction. [7] Oil production may be stimulated by injecting hydrochloric acid into the rock formation of an oil well , dissolving a portion of the rock, and creating a large-pore structure.

  8. Leaching (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Leaching_(chemistry)

    Biological substances can experience leaching themselves, [2] as well as be used for leaching as part of the solvent substance to recover heavy metals. [6] Many plants experience leaching of phenolics, carbohydrates, and amino acids, and can experience as much as 30% mass loss from leaching, [5] just from sources of water such as rain, dew, mist, and fog. [2]

  9. Marble - Wikipedia

    en.wikipedia.org/wiki/Marble

    Outdoor marble statues, gravestones, or other marble structures are damaged by acid rain whether by carbonation, sulfation or the formation of "black-crust" (accumulation of calcium sulphate, nitrates and carbon particles). [10] Vinegar and other acidic solutions should be avoided in the cleaning of marble products.
