Hard water increases films and stains from soaps, minerals, and other substances. Bathroom fixtures, sinks, dishes, and other surfaces need more frequent cleaning. Calcium and magnesium in water leave hard deposits called lime scale on fixtures and equipment.
These minerals make cleaning products less effective. To clean limescale, you need a “sequestrant” cleaner. Sequestrants capture and deactivate minerals in the water (Calgon is an example of a product with sequestrants). Deactivated minerals cannot react with other materials to form foam, film, or lime scale.
Also, think acid. Anything with acidity can help remove hard water stains on any surface. The general types of cleaners described below will help you remove stains from surfaces in the house. It is better to clean the stains regularly. If they are allowed to penetrate the surface, they become more difficult to remove.
Be sure to follow label directions for safe use of cleaners. You may need to open a window or use a fan for proper ventilation. Store cleaners in a safe place and properly dispose of empty containers.
Basic limescale removal
* Scrub the area with warm tap water to remove dirt and soap residue first. Afterwards, dry with a towel or cloth. The lime stain is much more difficult to remove with the dirt and soap scum intact, so you must first deal with the problem layer by layer, or you risk making the stain worse and harder to remove.
* Vinegar or lemon juice can be rubbed on the stain to dissolve it. Many people use vinegar to clean coffee makers, dishwashers, and garbage disposal. Go get some Heinz white vinegar or even something generic; It does not matter which one. Soak a brush in vinegar and begin to scratch the stain.
Lemon juice is also suggested because it works on the same principle as the white vinegar solution. You can use the juice or exfoliate with the lemon itself; that is, cut a lemon in half and rub it directly on the stain.
The acetic acid from either method should cut through the soap scum and help dissolve the organic compounds left in the bathroom grime. Rinse well. After stains have dissipated, follow up frequently with white / lemon vinegar cleanings to prevent stains from reappearing.
* Use a brass brush and a little bleach. Bleach is a chemical that removes color or bleaches, often through oxidation. Common chemical bleaches include household “chlorine bleach,” a solution of about 3-6% sodium hypochlorite (NaOCl), and “oxygen bleach,” which contains hydrogen peroxide or a peroxide-releasing compound such as perborate. sodium or sodium percarbonate.
Sodium hypochlorite is used in endodontics during root canal treatments, disinfecting the canal and dissolving any remaining pulp tissue; The same process is used to dissolve hard water buildup in bathrooms, sinks, pots and pans.
* Boil some rhubarb in a lime-stained pot. Rubarb is a genus of perennials that grow from short, thick rhizomes. The plants have large leaves that are somewhat triangular in shape with long, fleshy petioles, and the latter are readily available in most grocery stores.
Rhubarb is particularly effective at removing lime stains because it absorbs most brands through the abundant amount of absorbent acid it contains. When you’re done, throw away the debris from the plant and then clean it up as usual.
* Ammonia can work too, but should never be mixed or used in conjunction with bleach because they can form toxic fumes.
* If all else fails, consider using stronger acids to finish the job. For example, oxalic acid is effective as a rust remover; Phosphoric acid is often found in cleaning products that remove hard water deposits; and hydrochloric and sulfuric acids are sometimes used in dilute concentrations in toilet bowl cleaners.
Commercial lime stain remover
Shop around if vinegars and lemons aren’t enough; you may need a more powerful approach. Check hardware stores and grocery aisles for tougher chemical cleaners. Commercial products designed to remove hard white limescale can be used if the label says they are surface safe.
* Lime-A-Way is a product found in most stores; if you have hard water, it is a must. You can use it for many applications. To clean the sink and tub, spray it on the stained spots and let it sit for up to 15 minutes, depending on how dirty they are, then clean and rinse.
Once you’ve cleaned the sink / tub, use the same sponge to quickly go through the taps – it makes them so shiny and clean you’ll think they’re new.
* Bar Keepers Friend is a powdered cleaner that works wonders in pots and pans. However, do not use it on non-stick surfaces. Dampen the surface of the pot and sprinkle a generous amount of BKF into the pot. Use a sponge to rub in a circular pattern. Rub and rinse. Your pots will shine.
* Calgon is a product that consists of powdered sodium hexametaphosphate (amorphous sodium polyphosphate), which in water would form a complex with the ambient calcium ion and certain other cations, avoiding the formation of unwanted salts and the interference of those cations with the actions of soap or other detergents.
