Evaluating these variables ensures you choose the optimal system for your facility’s production workflow, maintenance goals, and compliance standards.
Parts washers represent a crucial investment and require regular maintenance to ensure optimal performance. For parts washers that are used frequently, weekly checks may be necessary to maintain their efficiency and proper operation. Below are some key steps to follow when assessing the condition of a parts washer.
The first step in effective maintenance is to familiarize yourself with the parts washer's components. Understanding how each part functions helps in identifying potential problem areas that may require closer inspection. Components such as tanks, heaters, pumps, nozzles, filters, and turntables can experience malfunctions or may not perform as expected.
The filter is a crucial component of the parts washer and should be checked regularly for buildup that can lead to clogging. It is generally recommended to replace the filter monthly, or more frequently based on the frequency of use. To prolong the life of the filtration system, consider pre-cleaning parts before placing them in the washer.
In spray-type parts washers, spraying is the most straightforward and cost-effective method for cleaning parts. It is important to regularly check the spray patterns to ensure they provide complete coverage and verify that the water pressure is adequate.
The pump generates the necessary pressure for the system and should be inspected for proper alignment and any required adjustments. Regular maintenance should include checking the pump’s bearings, depending on their location, and ensuring they are properly lubricated.
Certain cabinet parts washers feature a turntable that rotates parts for thorough cleaning. The turntable is driven by a set of gears, so it's crucial to ensure it operates correctly. Regularly check the bearings for proper lubrication and ensure the gears are aligned to prevent slippage. Additionally, monitor the turntable's weight capacity to avoid overloading. While washing more parts at once can reduce the overall cleaning time, the pump must have a high gallons-per-minute capacity to adequately cover all surfaces.
The turntable cleaning method can also incorporate indexing, where parts are washed individually. In an indexing system, parts are loaded onto a rotating fixture either manually or robotically. The fixture then indexes through timed cycles, typically ranging from three seconds or longer, moving the parts into high-pressure spray zones to effectively remove chips and oils.
Proper leveling of a parts washer is crucial for its optimal performance. Leveling is typically part of the installation process. Although rare, it is advisable to check the washer’s level if a malfunction occurs. For small, portable parts washers, ensuring the device is level during setup is essential and usually outlined in the manufacturer’s instructions.
Parts washers produce waste during the cleaning process, and proper disposal is essential. This waste should not be disposed of in onsite septic systems, as it can cause contamination. Waste may be managed by evaporation in some systems, but local regulations vary. Some municipalities allow waste to be discharged into the sewer system, so it is important to check with local regulatory agencies to ensure compliance with disposal guidelines.
When preparing parts for cleaning, avoid overfilling or tightly packing the cleaning basket, as this can result in inadequate cleaning and may require re-cleaning. To ensure parts are thoroughly cleaned, use methods such as visual inspection, particle counting, and other testing techniques.
Parts with burrs, cleaned using solvent or aqueous methods, can present challenges during the cleaning process. Thermal deburring is the most effective method for ensuring complete removal of these burrs.
Choosing the right solvent or cleaner is crucial for effective parts cleaning. Parts that are coated with oil-based coolants from machining processes require solvents specifically designed for hydrocarbon removal. For parts cleaned from grinding or lapping operations, an aqueous cleaning method is typically more suitable. Selecting the correct cleaner and cleaning process can significantly improve efficiency and reduce the time needed for parts washing.
When the cleaning solution becomes saturated with grime, dirt, and other contaminants, its ability to effectively clean diminishes, as the solution can no longer handle the volume of grease and oil. While using a skimmer or sludge scraper can help manage this issue, they do not completely eliminate the need for periodic cleaning of the parts washer tank.
A key component of a parts washer is the type of chemical or detergent used for cleaning. The choice depends on the type of parts being cleaned and the cleaning method. Chemicals and detergents for immersion cleaners differ from those used in ultrasonic or spray parts washers.
Parts cleaning often involves detergents and solvents that can be hazardous, dangerous, and toxic. Effective parts washer management includes monitoring the workplace environment to ensure proper control of these materials, thereby preventing potential injury and illness.
Washing parts is a complex process that requires specialized materials to effectively remove grease, grime, oil, chemicals, and soil from high-volume parts production.

There are a variety of methods used to assess the cleanliness of parts. These methods range from simple visual inspections, such as wiping a part with a cloth, to more sophisticated tests involving chemical reactions. Because there are no universal cleanliness standards, the evaluation of cleanliness can be somewhat subjective. Below are some commonly used tests for determining part cleanliness.
The cotton swab test is a straightforward method where the surface of a part is wiped with a white glove or cotton swab. The glove or swab is then inspected for any residual contaminants. This visual inspection determines whether the part meets cleanliness standards based on the presence or absence of residues.
The dyne test measures the surface wetness or tension of a part. This simple test involves marking a flat area of the part with a pen, marker, or ink. If the ink beads up instead of spreading out, it indicates that the part's surface is contaminated.
The gravimetric test quantifies particulate matter on a part by measuring different levels of microns (ÎĽm), from as low as 2 ÎĽm to several microns. Initially, the part is washed with a solvent to determine its level of contamination. After cleaning with a chemical like acetone, the solvent is filtered to separate non-soluble contaminants. These contaminants are then analyzed for amount, weight, size, and type.
FTIR is used to assess organic cleanliness by scanning the infrared spectrum absorption rate of a part. The part is first rinsed in a solvent and then scanned to evaluate the organic residues before and after cleaning.
The TOC test measures the total, organic, and inorganic carbon content in dissolved carbon dioxide and carbonic acid salts. This test is performed before and after cleaning to gauge the efficiency of the cleaning process and to check for any remaining alkaline content.
This test checks for the presence of oil and hydrophobic films on freshly cleaned metals such as stainless steel, titanium, steel, aluminum, and brass. The part is immersed in clean water at an angle. The formation of water droplets that do not spread evenly indicates the presence of residues or oils.
The conductivity rinse test is conducted before, during, and after the rinsing process. Changes in the conductivity of the rinse water are used to evaluate the effectiveness of the rinsing process.
The ROSE test detects ionic contamination by using solvent solutions to extract ions from the part's substrate. The resistivity of the solution is analyzed before and after cleaning to determine the level of ionic contamination in units per square inch.
Similar to the ROSE test, ion chromatography uses thermal extraction to collect ionic species into a solution, which is then analyzed using an ion chromatograph. The test measures the level and type of ionic species and the conductivity of the extracted solution.
Precision cleaning is crucial for removing contaminants, meeting cleanliness parameters, and adhering to industry standards. While the concept of cleanliness might seem straightforward, each industry has its own interpretation, parameters, and requirements for cleanliness. Additionally, companies set their own cleanliness goals that must be met before a part is approved for use or shipment.
Parts washer manufacturers produce equipment that cleans parts to precise micron (µ) or micrometer levels, which are significantly smaller than inches or millimeters. This precision is critical due to the specific nature and use of the parts. Some parts washers clean to as low as 2 µm, while others may clean to 50 µm.
Accurate and precise cleaning is essential for ensuring the proper functioning of parts and preventing damage to equipment and components.
Precision cleaning is increasingly essential for enhancing the usability, safety, and longevity of parts. Modern manufacturing processes introduce various contaminants and unnecessary materials that must be removed through multiple cleaning methods.
