Remove rust stains from the bathtub

Four coatings are common in bathtubs, from which the formation of rust stains and their method of disposal depend. Plastic, ceramics, porcelain or enamel can either bind rust or, if the surface is damaged, "migrate" corrosion raw materials from ferrous substructures onto the surface.

Rust or deep corrosion

Modern bathtubs and sinks are often made entirely of specialty plastics with fiber reinforcements. If rust marks form on their surfaces, they are deposits. Depending on the nature of the plastic and its sensitivity, it is above all middle combinations that usually have good acidity during removal.

The same applies to undamaged ceramic and enamelled tank coatings. However, even fine invisible hairline cracks in the surface can cause the escape of corrosive molecules from a ferrous metal substructure. In this case, in addition to removing a post-seal must be performed to prevent constant redevelopment of rust spots.

Partial and complete removal

Especially old bathtubs and freestanding models have a metal body. If it is ferrous metal, depending on the intensity of the corrosion attack, intensive rust removal methods of metal must be used.

In case of deep corrosion under the inner coating of a bath, the body may need to be exposed and the rust stains on the substructure removed. Subsequently, a new inner coating must be applied.

For rust spots on outer components of the bathtub such as feet or outer wall in free-standing models, the corrosion is partially treated, such as on a vehicle.

Auxiliaries for the production of cleaning paste

A bath allows a good incorporation of pastes on the corroded surfaces and points by their shape. As rusting or neutralizing pastes three mixtures can be mixed:

1. Sodium borate and citric acid
2. Tartar and hydrogen peroxide
3. Lime and salt
4. Vinegar and oil
5. salt and lemon juice

All ingredients are available in drugstores and partly in traditional supermarkets. The rust stains are rubbed with the respective pasted paste. After two to four hours of exposure, the dried paste is rinsed with hot water.

Tips & Tricks

Strong acids should not be used during rust removal. If the rust is so stubborn that it resists paste cleaning, there is sealing damage. When toxic acids are used, they can penetrate into cavities and wash out again at a later bath.
