At the present time there is a problem in storage of agriculture machine-tractor park, because when operating of agricultural machinery parts thereof are covered by contamination. The most heavily becomes dirty machinery working in the toughest conditions. Pollution promotes decrease the operational reliability, accelerating of corrosion and aging, reduce the quality of maintenance service and performance technique. One of the number of important factors when setting technique for storage is the clearing of by of various types pollution, because the during storage of cleaned surfaces, components and parts are subjected still greater destruction and corrosion. Removal of various kinds of pollution is an important technological process which has a significant impact on the preservation of appliances, performance of work, the quality of the repair and maintenance of cars, culture, production and human health. The article contains a classification of contamination depending on the difficulty of their removal and density, basic information on techniques and devices for purification of units and parts of agricultural machines, as well as on substances used for this. We have reviewed bombardment of surfaces with contaminated carbon dioxide ice particles that leads to its full destruction. We have improved technology and created a universal device and the experimental plant for cleaning parts and assemblies prior to storage, which are not only inferior, but also in the majority superior to technical and economic performance of existing analogues

The carried out analysis studies the influence of various factors on the preservation of agricultural products and shows that it is largely determined by design features of machinery and technological methods of use. The efficiency of agricultural and mobile trailer machines has been forming by service and storage. Low quality of work associated with the storage of agricultural machines is conditioned by the fact that the lack of financial capacity of rural producers on acquisitions of modern equipment and materials for carrying out the preparation of for long storage, and also the construction of modern agricultural machinery storage sites. If a car can be fully or partially protected from the solar radiation, rain and snow, simply by removing it in the room, under a canopy or covered with a protective cover, by the formation of condensation on the surface of the machine units and parts these ways to protect do not work. Enhancing of preservation of agricultural machinery is possible when protecting the vehicles from atmospheric precipitation in the form of snow and rain, influence of solar radiation, and also due to the change heat exchange processes of the machine with the environment that prevents the formation of moisture condensate on its surface, ie. we have to create conditions when cooling rate at which the surface of the machine would be equal to or less the rate of cooling air. This is possible through the use of a special design, which would prevent the intense heat radiation of the machine into the environment, ie, would reflect heat rays using its surface and return them to its surface and thus fulfill the role of the heat shield
