CLEANING IN GENERAL; PREVENTION OF FOULING IN GENERAL

Introduced: September 1968

Description

B08B covers general cleaning methods and apparatus not specific to particular surfaces or objects, along with techniques for preventing fouling (unwanted accumulation of deposits, biological growth, or corrosion). This subclass includes mechanical cleaning processes, chemical cleaning treatments, and combined cleaning systems applicable across diverse industrial and commercial contexts. It encompasses preventive measures such as coatings, additives, and operational methods designed to inhibit fouling on equipment and structures. More specialized cleaning directed at particular substrates, machinery types, or applications is classified in related subclasses.

Of 17 combined children, 10 exist in both systems.

7 codes are CPC-only extensions.

Note: 7 CPC extensions are marked as secondary classification only.

3 shared codes have differing titles between IPC and CPC.
