2. Cleaning agent - Wikipedia

   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.

3. Concrete sealer - Wikipedia

   en.wikipedia.org/wiki/Concrete_sealer

   Topical sealers can provide visual enhancement as well as topical protection from stains and chemicals. They require a dry, clean surface during application to gain adhesion. Topical sealers may alter the coefficient of friction which can make substrates slick when wet – a condition that can be remedied by adding anti-skid materials.

4. Calcium Lime Rust - Wikipedia

   glycolic acid; sulfamic acid; disodium capryloamphodipropionate; ethylene glycol n-butyl ether; citric acid; One formulation is (by weight) lactic acid 12–18%, gluconic acid 2.50–3.75%, lauramine oxide 1.50–3.25%, with the remainder being water. [3] The product also contained phosphoric acid at one time, [citation needed] but it is now ...

5. Descaling agent - Wikipedia

   en.wikipedia.org/wiki/Descaling_agent

   Limescale build-up inside a pipe reduces both liquid flow and thermal conduction from the pipe, so will reduce thermal efficiency when used as a heat exchanger.. A descaling agent or chemical descaler is a liquid chemical substance used to remove limescale from metal surfaces in contact with hot water, such as in boilers, water heaters, and kettles.

6. Hydrochloric acid - Wikipedia

   en.wikipedia.org/wiki/Hydrochloric_acid

   Hydrochloric acid, also known as muriatic acid or spirits of salt, is an aqueous solution of hydrogen chloride (HCl). It is a colorless solution with a distinctive pungent smell. It is classified as a strong acid. It is a component of the gastric acid in the digestive systems of most animal species, including humans.

7. Toilet cleaner - Wikipedia

   Toilet cleaner is sprayed around the rim and into the bowl of the toilet prior to the use of the toilet brush. The toilet brush is used to scrub the toilet, removing stubborn stains and biological debris. In recent times, automatic toilet bowl cleaners that clip onto the rim of the toilet and clean with every flush have also become prevalent.

8. Calcium hydroxide - Wikipedia

   en.wikipedia.org/wiki/Calcium_hydroxide

   This reaction is the basis of aerated concrete. [8] It does not corrode iron and steel, owing to passivation of their surface. Calcium hydroxide reacts with hydrochloric acid to give calcium hydroxychloride and then calcium chloride. In a process called sulfation, sulphur dioxide reacts with limewater: Ca(OH) 2 (aq) + SO 2 (g) → CaSO 3 (s ...

9. Stain removal - Wikipedia

   en.wikipedia.org/wiki/Stain_removal

   Oxalic acid is used widely as an acid rinse in the laundry industry due to its ability to remove rust and ink stains. Oxalic acid converts insoluble iron compounds into a soluble complex ion. It is because of this property that oxalic acid is one of the primary components in commercial solutions used to remove scale from automobile radiators. [5]
