A stain is a contamination on the surface of a material, such as textiles. Stains can occur in a variety of ways, and have a broad range of causes. Here, there are four main categories:
In addition, there is also a category of special stains, such as rust and the so-called mixed stains, which consist of a combination of different stain types.
Because no two stains are the same. There is a broad range of stain types with very different structures and properties. If the aim is to remove a certain stain, the stain remover must take into account the respective structures as well as properties and counteract them. Surfactants which reduce the surface tension of water and facilitate the stain removal are used for a successful stain removal, for example, of grease stains. In pigment-containing stains (e.g. pen or makeup) certain active substances dilute and release the pigments and through this remove to the stain. Bleachable stains are removed by oxidation, i.e. with the help of oxygen. To effectively remove most common stains, Dr. Beckmann therefore offers a range of eight customized stain removers, which are specialized for the removal of certain stain types.
Unfortunately, no. Non-removable stains can, for example, be caused by
Stains which are pigment-based and have been washed before the stain removal and/or have been ironed in, also can't be removed anymore.
Stain soap consists of soap and an extract from the gall-bladder of an animal, which is industrially produced according to high quality standards. The purpose of the gall-bladder is to emulsify fats and to make them soluble in water.
Bleaching agents remove stains from fruits, vegetables, tea, coffee, wine etc. through oxidation, i.e. with the help of oxygen. They also brighten the whites and have an antibacterial effect. Because of the brightening effect we recommend carrying out a colour-fastness test on coloured textiles before the actual treatment. Textiles made of new or merino wool as well as cashmere may not be treated with bleaching agents, because these would attack the protein-rich natural fibres.
The reaction of a substance with oxygen is commonly referred to as oxidation. In a more comprehensive explanation, it is described as a chemical reaction during which electrons are emitted. A practical application for this is the oxygen-based bleaching.
Surfactants are active washing substances, which reduce the surface tension of the water. Thus, a better wetting of the fibres is achieved and especially the dissolving of oil and greasy dirt from textiles facilitated. There are 4 main groups of surfactants: anionic tensides, non-ionic surfactants, cationic surfactants and amphoteric surfactants.
They are certain proteins that speed up various chemical processes within in an organism, or they are what actually enables them. In cleaning applications, enzymes support the decomposition or "dissolving" of organic contaminants, and are therefore used as an essential component of cleaning and stain removal products. Enzymes are highly effective proteins, which are able to even perform functions in small quantities and at low temperatures. Depending on their effect there is a distinction between: amylase, cellulase, lipases and proteases.
Solvents are liquids which dissolve active ingredients without changing their composition. They contribute to the cleaning effect and partly evaporate after the application. They are commonly used for the removal of stubbornly adhesive dirt such as oil, fat, wax, tar, paints, coatings and adhesives.
Laundry additives are products that are used as supplements for the washing powder and boost the washing performance.
Optical brighteners are compounds with fluorescent properties. Their purpose is to increase the whiteness-degree of a textile by compensating for the yellowish tint: the ultraviolet light absorbed from sunlight is radiated again as a weak bluish fluorescence, which is the complementary colour of the yellowish tint. This will cause the textile to appear "whiter".
There are two types of natural fibres:
There are two types of man-made fibers:
Both types of man-made fibers are synthetically manufactured fibers.
For a successful stain removal, it is important to know whether a textile is colour-fast or not. Therefore, we always recommend that a colour-fastness test be performed. For this, soak a clean, white cloth with some Stain Devils solution. Dab this cloth onto a concealed place of the textile, for example, on the inside hem of the fabric. The white cloth may not absorb the colour of the fabric. The stain removal can be performed if neither the colour nor the structure of the fabric has changed, after the test area was exposed to the fluid, and then washed and dried.
Acids are (usually highly) corrosive liquids, which should be handled very carefully (for example, hydrochloric acid, sulphuric acid, nitric acid). With certain acids it is possible to dissolve lime, and to dissolve and remove rust.
Ammonia, soda, sodium, and potassium hydroxide are the main ingredients for dirt-dissolving alkalis, which are able to remove particularly stubborn grease and oil-based deposits (e.g. in the oven) and obstructions (e.g. in the drain). However, alkalis are unable to dissolve lime. Cleaners which mainly consist of strong bases are corrosive. The hazard labels and safety notices must be precisely observed.
In abrasive substances, metal polishes and oven cleaning agents, the so-called abrasive components serve as mechanical grinding and polishing elements. Their grain size and hardness is composed in such a manner, that the surfaces are cleaned without being destroyed.
