Rust stains are very often in bathroom, especially if you are living in house with old pipes. They can occur if you are using water with high iron content or if your galvanized pipes are rusty. Some rusty stains are very difficult to remove or even impossible if the stains have etched into the porcelain. In this post, you will find how to remove hard stains.

Be aware that you may have to use some strong chemicals. It is a good idea to consult with a specialist before using chemicals, especially if you are using septic systems. It is bad idea to use chlorine bleach, it only sets the iron stain. Usually the rust stains can be removed with oxalic acid solution.

One of the best tools for your fight with the rust is Zud. It is cleaning powder that contains oxalic acid. For rust stains on hard surfaces, you can use oxalic acid crystals. Dissolve them in a small amount of hot water and add some whiting or talc to make a soft paste. Then use the mixture to the stain and let it to dry. When it is dry, just rinse and polish. Be very careful with this mixture because it is poisonous.

The Works is another chemical cleaner good for removing rust stains. It very easy to use, just spray it on the rusty surface, let it set and rinse it. Be VERY CAREFUL because the product contains about 20% hydrochloric acid and can be dangerous and never use it for septic systems.

For around $10, you can buy Shaw’s Pads Toilet Ring Remover. These pads are safe for septic systems because they do not use chemicals. They are very easy to use, you just have to wet the pad and use short vigorous strokes. Then the scale and staining comes free from the porcelain.

To remove small rust stains you can use salty lemon. First, pour a pile of table salt on top of the rust stain and then squeeze lemon juice over it. This pile of salty lemon juice must stay for several hours. When it is ready, you will probably see the rust in this pile of salt and lemon juice.
