Iron stains, or rust, are common issues that affect many bathtubs. Iron in the water supply can often lead to a gradual build up of iron stains, but also leaving metal products lying around can cause a similar result.
Most iron stains can be wiped away, if spotted early enough. Most bathroom cleaners applied to a damp cloth will be enough to clean the bathtub. If left untreated though iron stains can become stubborn and much harder to clean.
There are many bathroom cleaners on the market, although it is essential that any products used on the bathtub are non-abrasive, otherwise they may cause some damage in the form of small scratches. Additionally there are many rust removal agents available to buy as well, these of course will move iron stains from bathtubs as well. Some care though is needed because most of these products contain oxalic acid, which can be dangerous. One of the most common products though used to remove iron stains is known as CLR, (Calcium, Lime and Rust Remover, although this to does require some care as over use can damage the bathtub.
Stubborn iron stains though may require a lot more elbow grease and the use of a pumice stone, or pumice scouring pad, in addition to any iron stain removal product.
It is also possible to make your own iron stain removal products through the use of oxalic acid crystals, talc and hot water. This creates a paste, but again care needs to be taken as oxalic acid is poisonous and thus dangerous. Although less dangerous the use of hydrogen peroxide as a cleaning compound as similar dangerous connotations. Chlorine bleach is a common household cleaner, although it may not work especially well on iron stains as it does occasionally cause the stain to be come more set in.
There are though a number of possible solutions to the cleansing of iron stains which does not involve the use of cleaning products. Many products found around the home can be used to make iron stain removal products. A paste made from baking soda, or simple non-abrasive toothpaste can be used to remove iron stains. Another more unusual cleaning product though makes use of salt and lemon juice. Pouring salt onto an iron stain and then dripping lemon juice onto it will result in a chemical reaction. After a few hours the rust transfers from the bathtub into the pile of salt.
Iron stains can be removed from bathtubs, although they are easier to remove if dealt with quickly. Some elbow grease may be involved but a bathtub can be free from iron stains.
