How to get rid of rust spots on concrete
Many people face the problem of some rust spots appearing on concrete, especially if their homes use well water, as this water contains a large amount of iron that helps in the formation of this rust, and in fact, it is difficult to prevent the appearance of these spots or remove them completely. Especially if it has been in existence for many years, but there are some means by which it can be greatly reduced and made invisible clearly.
How to remove small rust stains:
Before starting the cleaning process, the concrete must first be washed well-using soap and water, to prevent dirt from accumulating between the clean areas and rust spots because this hinders the cleaning process and gives ineffective results. After the concrete is washed and dried, is sprayed Lemon juice on the rusted area.
Lemon is one of the most important materials that can remove rust and stains, as the citric acid in it facilitates the cleaning process, so after spraying lemon, it is left in the place of rust for about 10 minutes and then rubbed well using a wire brush, bearing in mind that the brush has dry bristles And that the cleaning process is done in small circles.
If the stains are difficult, white vinegar is used instead of lemon, and after completion, the place is washed well with cold water and then the concrete is left to dry, and this previous step can be repeated more than once to ensure that the stains are disposed of well, as washing helps for several times to get better results in cleaning.
If the surfaces are thin or painted, the wire brush can be held with a sponge moistened with warm water and used in the cleaning process, with the need to ensure that the cleaner does not harm the paint. A cup of vinegar and water can be prepared to wash the surface with it in a circular motion. This step is required to be repeated more than once to obtain satisfactory results.

It is also possible to use hydrochloric acid in the cleaning process, as experience has proven that it is the best in removing rust stains, but leaving it for a long time on the surface may lead to a blue color, so it is preferable to dilute it with a little water, and leave it for a period not exceeding About 10 minutes after which it is removed and cleaned.
A nylon brush with dry bristles is used to scrub the place of rust, where the cleaning is in circular motions, and after completion, the cleaning place is washed well to get rid of the rust permanently, and the cleaning must be expedited so that the cleaner does not cause discoloration of the surface as a result of leaving it for a long time without rinsing it
If there is a problem in the process of washing the stains or difficulty in rubbing it, it is possible to use a hose to press the water, as it ejects the water with great force, which makes it able to clean the place of the acid well, and its concentrated force helps to remove the remains of stains on the surface in a way ultimate.
