3. Safety: Removing harmful contaminants such as oil, grease, and chemicals helps prevent accidental slips and injuries in the workplace. Cleaner parts also reduce the risk of fire hazards that can arise when flammable substances accumulate on machinery.
   
4. Cost Savings: Regularly cleaning and maintaining parts extends their useful life, which can ultimately save money by reducing the need for replacements or costly repairs. Using a parts washer also helps reduce manual labor, which can be time-consuming and inconsistent.
   
5. Environmental Benefits: Modern parts washers are designed with environmental concerns in mind. They often use non-toxic, biodegradable solvents and allow for the recycling of used fluids, reducing waste and helping businesses comply with environmental regulations.
   

How Parts Washers Work
The operation of a parts washer depends on its design and the type of cleaning mechanism it employs. Here’s a breakdown of how typical parts washers function:

1. Solvent or Water-Based Cleaning: Parts washers generally use either a solvent-based solution or a water-based solution to remove contaminants from parts. Solvent-based washers are effective at dissolving grease and oil, while water-based cleaners are more environmentally friendly and less toxic.
   
2. Mechanical Action: Many parts washers utilize mechanical mechanisms such as rotating brushes, spraying nozzles, or agitating baskets to clean the parts. These actions help dislodge stubborn dirt and grime that may be stuck in hard-to-reach places.
   
3. Heating: Some parts washers have heating elements that warm the cleaning solution, making it more effective at breaking down grease and grime. Heated solutions also speed up the cleaning process, allowing for quicker turnaround times on cleaning tasks.
   
4. Filtration and Recycling: Advanced parts washers feature filtration systems that help remove debris and contaminants from the cleaning solution. This allows the solution to be reused, reducing waste and lowering operating costs. Some machines even have oil skimmers or coalescers to separate oil from water-based cleaners.
   
5. Drying Process: After cleaning, some parts washers have drying mechanisms such as forced air or heating elements to ensure that the cleaned components dry quickly. This helps avoid the accumulation of moisture, which can lead to rust or corrosion.
   

Types of Parts Washers
There are several types of parts washers, each suited for specific cleaning needs and applications. Let’s take a closer look at the most common types:
1. Solvent Parts Washers
Solvent-based parts washers use chemical solvents to break down grease, oil, and other contaminants. These washers are particularly effective in environments where heavy grease buildup is common, such as in the maintenance of machinery used in construction or mining. Solvents such as petroleum-based products, citrus-based cleaners, or bio-based solvents are often used.
Advantages:

• Effective at dissolving grease and oils
  
• Great for cleaning heavy-duty equipment
  
• Available in both manual and automated models
  

Disadvantages:

• Environmental concerns due to the use of chemicals
  
• Toxicity of certain solvents
  
• Disposal of used solvents can be costly
  

2. Water-Based Parts Washers
Water-based parts washers use a water-based solution, often combined with detergents or other cleaning agents, to remove contaminants from parts. These washers are environmentally friendly and safe to use in a variety of applications. They are suitable for cleaning parts where grease and oil are less prevalent.
Advantages:

• Environmentally friendly
  
• Less toxic than solvent-based washers
  
• Easier to dispose of used cleaning fluids
  

Disadvantages:

• May not be as effective for heavy grease buildup
  
• Requires periodic changes of the cleaning solution
  

3. Aqueous Parts Washers
Aqueous parts washers are a type of water-based washer that uses heated, pressurized water mixed with biodegradable detergents. The heat helps dissolve grease and oils, and the pressurized water makes it more effective at removing contaminants from parts.
