When you use a paint sprayer, some paint inevitably gets left behind in the machine. Over time, this paint can dry and harden, making it difficult to remove and causing the paint sprayer to become less effective. If you don’t clean your paint sprayer properly after each use, it can lead to clogs and other issues that can affect the quality of your work.
That’s why it’s important to know how to remove old dried paint from a paint sprayer and to make sure you do so regularly. In this article, we will explore some of the most effective methods for cleaning a paint sprayer and answer some common questions about the process.

Materials and Tools
Before you begin cleaning your paint sprayer, there are several materials and tools you’ll need to gather. These include:
- Paint thinner or rubbing alcohol (depending on the method you choose)
- Dish soap (optional)
- Water
- Clean rags or towels
- A small brush or toothbrush for scrubbing
- Safety glasses
- Gloves
- Respirator or mask
Make sure you have all of these items on hand before you start cleaning your paint sprayer. Safety glasses and gloves will help protect your eyes and skin from any harmful chemicals or solvents, while a respirator or mask will help prevent you from inhaling any fumes. Additionally, it’s important to work in a well-ventilated area to avoid any potentially harmful exposure to fumes.
How to Remove Old Dried Paint from a Paint Sprayer
Disassembling the Paint Sprayer
To clean a paint sprayer properly, you’ll need to disassemble it to access all of the parts that need to be cleaned. Refer to your paint sprayer manual for specific instructions on how to take apart your machine. In general, you’ll need to:
- Turn off and unplug the paint sprayer.
- Remove the nozzle and other removable parts, such as the spray tip, fluid filter, and guard.
- Use a wrench to remove the inlet and outlet valves, if applicable.
- Use a brush to remove any excess paint on the inside of the paint sprayer.
Cleaning the Paint Sprayer
Using Paint Thinner
Paint thinner is a common solvent that can effectively dissolve old dried paint. Here’s how to use it to clean your paint sprayer:
- Pour some paint thinner into a bucket or container.
- Soak the paint sprayer parts in the paint thinner for several hours.
- Use a small brush or toothbrush to scrub away any remaining paint.
- Rinse the parts with water and dry them with a clean towel.
Note that paint thinner can be a hazardous material and should be handled with care. Be sure to wear gloves, a mask, and safety glasses when working with paint thinner.
Using Rubbing Alcohol
Rubbing alcohol is another effective solvent for cleaning a paint sprayer. It works best on water-based paints. Here’s how to use it:
- Mix equal parts rubbing alcohol and water in a bucket or container.
- Soak the paint sprayer parts in the rubbing alcohol solution for several hours.
- Use a small brush or toothbrush to scrub away any remaining paint.
- Rinse the parts with water and dry them with a clean towel.
Rubbing alcohol is less hazardous than paint thinner, but you should still wear gloves and safety glasses when using it.
Using Dish Soap
Dish soap can be an effective and gentle way to clean a paint sprayer. Here’s how to use it:
- Fill a bucket or container with warm water and a few drops of dish soap.
- Soak the paint sprayer parts in the soapy water for several hours.
- Use a small brush or toothbrush to scrub away any remaining paint.
- Rinse the parts with water and dry them with a clean towel.
Dish soap is a safe and affordable option for cleaning a paint sprayer, but it may not be as effective on stubborn or old paint stains.
Reassembling the Paint Sprayer
Once all of the paint sprayer parts are clean and dry, it’s time to reassemble the machine. Refer to your manual for specific instructions, but in general, you’ll need to:
- Reinstall the inlet and outlet valves, if applicable.
- Reattach the nozzle and other removable parts.
- Test the paint sprayer to make sure it’s working properly.
It’s important to make sure all of the parts are properly secured and tightened before using the paint sprayer again.
Can You Use Other Methods to Clean a Paint Sprayer?
While using paint thinner, rubbing alcohol, or dish soap are effective methods for cleaning a paint sprayer, some people may wonder if there are other methods they can use. Here are some other options to consider:
Using a Power Washer
A power washer can be a convenient way to clean a paint sprayer, but it’s important to be cautious. High-pressure water can damage the paint sprayer or cause it to malfunction if water enters the motor or other internal components. If you choose to use a power washer to clean your paint sprayer, be sure to:
- Use a low-pressure setting to avoid damaging the paint sprayer.
- Hold the power washer nozzle several feet away from the paint sprayer to avoid causing damage or water entry into the motor.
- Cover any electrical or motorized components with plastic bags to prevent water from entering them.
Using a Cleaning Solution
There are many commercial cleaning solutions available that are designed specifically for cleaning paint sprayers. These solutions are typically more expensive than using paint thinner, rubbing alcohol, or dish soap, but they may be more effective at removing stubborn paint stains.
When using a commercial cleaning solution, be sure to follow the manufacturer’s instructions carefully. Some cleaning solutions may require you to mix them with water, while others may be applied directly to the paint sprayer. You may also need to let the cleaning solution soak on the parts for a specific amount of time before scrubbing and rinsing them.
It’s important to note that some commercial cleaning solutions can be hazardous to your health or the environment. Be sure to wear gloves, a mask, and safety glasses when using them, and dispose of any leftover solution properly according to the manufacturer’s instructions.
Conclusion
Cleaning old dried paint from a paint sprayer is an important task that should not be overlooked. Neglecting to clean a paint sprayer can cause it to malfunction and produce poor results, and can even damage the machine permanently.
The good news is that there are several effective methods for cleaning a paint sprayer, including using paint thinner, rubbing alcohol, or dish soap. However, it’s important to disassemble the paint sprayer and follow proper cleaning procedures to ensure that it’s working properly and producing high-quality results.
Additionally, it’s important to use safety equipment, such as gloves and safety glasses, when handling cleaning solutions. With proper cleaning and maintenance, a paint sprayer can last for years and produce professional-looking results.
