Given that the DeWalt pressure washer provides only 200 PSI, it falls into the category of light cleaning tasks.
Types of Stone and Cleaning Considerations
When it comes to cleaning stone, various types will present their own challenges. Common types of stones include:
- Granite: Durable yet can be susceptible to scratches if pressure is too high.
- Marble: Porous and can stain easily, requires gentler treatment.
- Slate: Can be easily chipped or broken at higher pressures.
- Flagstone: Can withstand moderate cleaning but may still require caution.
Each type of stone can differ significantly in its durability and finish, and this should influence how you approach cleaning.
Is 200 PSI Enough to Clean Stone?
While 200 PSI might suffice for light tasks such as washing vehicles or garden furniture, its effectiveness on stone surfaces largely depends on several factors:
1. Type of Stone Being Cleaned
As mentioned earlier, different stones have varying resistance to pressure. Softer stones like marble are more likely to sustain damage at higher pressures, while harder stones like granite may withstand a light wash at 200 PSI.
2. Nature of the Stains
The type and depth of stains on the stone surface also play a crucial role. Light dirt or grime may be washed away easily with a DeWalt 200 PSI, whereas stains caused by oil or mildew may require higher pressure or additional cleaning solutions.
3. Distance and Angle of the Spray
The distance you maintain from the stone surface and the angle of the spray can greatly influence the performance of the pressure washer. A closer distance with a direct angle may focus the spray and enhance cleaning effectiveness, but it may also risk damage to fragile surfaces.
4. Use of Chemical Cleaners
Utilizing a compatible chemical cleaner or detergent can significantly improve cleaning efficiency, especially when using lower PSI machines. A mild stone cleaner can help break down tough stains, allowing the 200 PSI output to better assist in rinsing the residue.

Step 2: Choose the Right Nozzle
Most pressure washers come with interchangeable nozzles. For stone surfaces, a wider nozzle (25-40 degrees) is recommended as it allows for a broader spray, reducing pressure while still effectively cleaning.
Step 3: Pre-clean and Reassess
Consider pre-treating heavily stained areas with a chemical cleaner. Allow it to sit for the specified time before using the pressure washer. Reassess the state of the surface after pre-cleaning—if the stains are stubborn, you may need higher PSI.
Step 4: Maintain Distance and Angle
Stand at a distance of approximately 2-3 feet from the stone surface and angle the spray downwards to minimize the risk of damage. Always test a small, inconspicuous area first to see how the stone reacts.
Step 5: Rinse and Inspect
After cleaning, allow the surface to dry and inspect it for any remaining stains. If necessary, you may want to repeat the process or consider a different cleaning method for tough stains.
Alternatives to 200 PSI for Cleaning Stone
If you find that the DeWalt 200 PSI pressure washer is insufficient for your stone cleaning needs, here are some alternatives to consider:
Higher PSI Pressure Washers
Investing in a pressure washer with higher PSI (2000 PSI or more) will provide greater cleaning power. This will especially be necessary for external stone walls, driveways, or heavily stained areas.
Professional Cleaning Services
If the job is especially large or the condition of the stone is concerning, hiring professional cleaning services can save you time and ensure the work is completed safely.
Conclusion
In summary, the DeWalt 200 PSI pressure washer can be used to clean stone surfaces, but its effectiveness is dependent on various factors, including the type of stone, nature of the stains, nozzle choice, and cleaning techniques employed.
