The objective of this article is to compare and evaluate the most suitable washing technology of cleaning and degreasing machined parts after CNC machining, based on analysis of technological and economic criteria. Based on these criteria, costs of low-quality products are eliminated, production costs of manufactured parts are reduced, and the enterprise reaches higher profit. Increasing of quality of products and services is accompanied by the necessity of permanent investments into new production technologies that would move quality of products to the limit where they maintain or increase profitability of manufactured products, attract new customers, and thus bring profit to the company. Permanently increasing quality of products and services is understood as a never-ending cycle.
