Many people assume that once a cleanroom is built, the job is done. In reality, what determines success or failure over time is what happens afterward. Cleanroom maintenance is not basic housekeeping—it is a long-term, risk-driven management system built around standards, engineering controls, and operational discipline. As a professional cleanroom engineering provider, Wonclean uses this guide to explain what cleanroom maintenance really means and why it matters. What Is Cleanroom Maintenance—and Why Is It Different from Regular Cleaning? The goal of regular cleaning is simple: make a space look clean. The goal of cleanroom maintenance is very different: maintain continuous environmental control. Key differences include: Different control targets: focus on airborne particles and microorganisms, not visible dirt Standards-driven execution: all actions follow ISO 14644, GMP, USP, and related regulations Higher risk level: improper cleaning can lead to contamination, batch rejection, or regulatory penalties In real-world facilities, cleanroom maintenance functions as an ongoing clean room process, not a one-time task. Where Does Contamination Come From? Based on Wonclean’s project experience, contamination sources fall into four main categories: Primary Contamination Sources Personnel (>80%): skin flakes, hair, oils, respiratory aerosols External introduction: materials, tools, unclean equipment Internal generation: equipment wear, material aging Cleaning itself: shedding wipes, incompatible chemicals This is why training, procedure control, and proper tools are essential parts of any cleanroom program. Core Principles of a Standardized Cleaning SOP A compliant cleanroom maintenance program always starts with a clear and enforceable SOP. Four Golden Rules of Cleanroom Cleaning Top to bottom, clean to dirty Unidirectional movement—no backtracking Clean first, then disinfect (observe required contact time) Dedicated tools by area, with color coding to prevent cross-contamination These principles apply to all cleanroom classes, with increasing strictness at higher grades. A Step-by-Step Cleanroom Cleaning Example Many facility managers ask questions similar to how to clean your room step by step. Below is a typical workflow: Three-Stage Cleaning Process Stage 1: Preparation Personnel complete gowning procedures Approved wipes, disinfectants, and HEPA vacuums are prepared Non-fixed items are removed Stage 2: Execution Ceiling and air diffusers → walls → equipment → work surfaces → floors Overlapping “S-pattern” wiping with frequent wipe folding Floors cleaned dry first, then wet-disinfected Stage 3: Recovery Visual inspection under proper lighting Used materials sealed and removed HVAC recovery time observed and documented This structured approach defines true cleanroom cleaning, not casual sanitation.

Answer:Ensure the establishment of a scientific and strict sterile pharmaceutical production environment, process, operation and management system. Eliminate biological bacteria and produce high-quality and safe pharmaceutical products. If one link is not well controlled, no matter how good the production process is, no matter how good It is also difficult to ensure the quality of drugs
Through certain technical means, remove particles, bacteria, viruses, harmful gases and other pollutants in the air within a certain range, and at the same time, control the cleanliness, temperature, humidity, air pressure, wind speed, noise, and lighting parameters in the area Within a certain range of requirements. This project is called the purification project. This room is a clean room. The clean room originated in a hospital. In the 1880s, Lauder List realized that bacteria can cause infections in surgical wounds. Removing bacteria from the operating room can prevent infections, laying the scientific theoretical foundation for clean rooms. The clean room is developed in the precision instrument manufacturing industry. During World War II, people discovered that in order to improve the quality and reliability of guns, tanks, and aircraft equipment, the cleanliness of the production environment must be improved. Therefore, the first clean room for industrial production appeared in the United States. It can be said that the victory of World War II also contributed to the clean room. In the 1850s, the emergence of high-efficiency filters promoted the development of clean rooms. At this stage, clean rooms are widely used in industries such as microelectronics, optoelectronics, medicine, medical treatment, microorganisms, instruments, meters, aerospace, aviation, food, health products, and cosmetics. From our professional point of view, clean rooms are basically ubiquitous. There are many parameters that need to be controlled in the purification project, the most important thing is the number of particles, that is, the control of cleanliness. According to the maximum allowable concentration of particles of different particle sizes in the air, we mainly look at the particle concentration of 0.5 micron and 5 micron to divide the air cleanliness of the clean room into 100, 10,000, and 100,000 grades.
