The invention discloses a cleaning agent for a bearing and a bearing seat for a pump, and relates to the technical field of equipment maintenance. The cleaning agent is made of following raw materials including, by weight, 15 parts to 20 parts of ore soil, 10 parts to 15 parts of hydrogenated rosin, 10 parts to 15 parts of asbestos wool, 8 parts to 11 parts of tea seed powder, 6 parts to 9 parts of washing powder, 6 parts to 9 parts of stearic acid, 4 parts to 8 parts of cinerite, 3 parts to 6 parts of polyaspartic acid, 3 parts to 6 parts of sodium salicylate, 2 parts to 4 parts of soda ash, 1 part to 2 parts of aluminum powder, 0.5 part to 1 part of borax, 0.2 part to 0.3 part of a silane coupling agent and 200 parts to 250 parts of ethyl alcohol. The cleaning agent is convenient to use, and during use, a user only needs to dip a few cleaning agent by duster cloth to wipe the bearing and the bearing seat; and dirt attached to the surfaces of the bearing and the bearing seat can be thoroughly removed, the bearing and the bearing seat have the antirust function after being wiped, the phenomenon that the bearing and the bearing seat act with water or oxygen in environment to generate the corrosion phenomenon is avoided, the service life of the bearing and the bearing seat is prolonged, and therefore normal running of the pump is ensured.
