Dry cleaning of fabrics. It is carried out using organic solvents. Dry cleaning of antique fabrics is often the only way to remove dirt, and is then used, when wet cleaning is not possible. Fabrics must not be washed, when they are sensitive, brittle or not permanently colored or painted in a way that does not allow immersion in water.
Dry cleaning should be carried out, when the fabric is dry, decayed, and its fibers. they crack in water. This also applies to fabrics made of different fibers or a combination of different materials. Dry cleaning, generally, is more oriented towards respecting the monument than wet cleaning. The cleaning effects are also different. When using organic solvents, the fabric fibers do not swell, and there is no fear of shrinkage or shape deformation, which is especially important when it comes to clothes. Fragments of fabrics already present as compact limonite, they are also cleaned with organic solvents. Accelerated drying is achieved in this way, the necessary reinforcement is obtained by the simultaneous application of the impregnating agent.
Water-insoluble dirt is removed with organic solvents, especially grease-containing dirt. Often, however, they are not the main contamination of fabrics. Sometimes, after wet cleaning, it is necessary to carry out chemical cleaning, e.g.. lost, which have only now been revealed.
However, dry cleaning is often recommended for vintage fabrics, however, they must be pre-tested with specific organic solvents. It is also necessary to use solvents sparingly.
