Kärcher Multi Purpose Pressure Washer Detergent, Removes Dirt and Grime from Fences, Siding, Patios, Driveways, Sidewalks, Concrete and More, Highly Concentrated, Makes up to 20 gal of Cleaner
This Kärcher detergent is designed to complement most consumer pressure washers, including those from brands like Greenworks or Westinghouse, and stands out for its high concentration, allowing up to 20 gallons of diluted cleaner from just one gallon of concentrate. Unlike surface cleaners that focus solely on flat surfaces, this soap helps loosen dirt across various materials, making it ideal for combining with surface attachments like the Westinghouse 16.5″ model for enhanced results. While it excels at general cleaning and is compatible with multiple brands, it requires a separate attachment for surface cleaning, which could be a drawback for those seeking an all-in-one solution. Tradeoffs include the need for a pressure washer to use it and manual application for best results. This product makes the most sense for homeowners who want a highly concentrated, multi-surface cleaner compatible with their existing pressure washer, but not for users seeking an all-in-one surface cleaning tool.
Pros:- Highly concentrated, making up to 20 gallons of cleaner from just one gallon
- Compatible with most consumer gas and electric pressure washers
- Effective across multiple surfaces including concrete, siding, and fencing
Cons:- Requires a separate surface cleaner attachment for flat surface cleaning
- Manual application may be needed for optimal results
Best for: Homeowners needing a versatile, concentrated detergent for large cleaning jobs across different surfaces

- Compatibility:Most consumer gas & electric pressure washers
- Made in:USA
- Material:Concentrated liquid
Bottom line: This detergent is ideal for users seeking a powerful, versatile cleaning solution that works with their existing pressure washer, but not for those who want an all-in-one surface cleaning attachment.

This 15” surface cleaner from Westinghouse is designed for large-scale flat surface cleaning, boasting a maximum PSI of 3400, which makes it suitable for decks, driveways, and patios. Compared to the Greenworks 12” model, this attachment covers a wider area, reducing cleaning time significantly, especially on expansive surfaces. Its universal compatibility with most pressure washers using a 1/4” quick connect makes setup straightforward. However, at 4 pounds, it’s lightweight but may require careful handling at higher pressures to prevent wobbling. Tradeoffs involve a slightly lower PSI maximum than the Westinghouse stainless steel model, but it offers greater coverage for bigger jobs. This pick makes the most sense for homeowners or small businesses tackling large, flat surfaces with compatible pressure washers, but less so for those with smaller or more delicate areas.
Pros:- Wide 15-inch cleaning path for faster coverage
- Universal 1/4-inch quick connect compatibility
- Lightweight at 4 lbs for ease of handling
Cons:- Maximum PSI of 3400 may be insufficient for some heavy-duty cleaning

Not ideal for: Users with small or intricate surfaces requiring precise, detailed cleaning
- Max PSI:3400
- Connector:1/4 inch quick connect
- Weight:4 lbs
- Cleaning Width:15 inches
Bottom line: This surface cleaner is perfect for large-area jobs where speed and coverage are priorities, but not for heavy-duty or highly detailed cleaning tasks.

This stainless steel 16.5” surface cleaner from Westinghouse offers a higher PSI capacity of 4400, making it suitable for demanding cleaning tasks on large surfaces such as brick, concrete, or wood. Compared with the 15” model, the increased size and PSI capacity enable faster, more aggressive cleaning, which is ideal for professional or serious homeowner use. Its durable construction ensures longevity, even under frequent use. The quick-connection system simplifies setup with most gas and electric pressure washers, and the 180-day warranty adds peace of mind. However, its larger size and weight might be slightly less maneuverable for tight spaces. Tradeoffs include higher cost and increased size, but the durability and PSI capacity justify it for heavy-duty projects. This product is best for contractors or homeowners with extensive flat surfaces and high pressure washers who prioritize durability and efficiency, but less so for casual users with smaller areas.
Pros:- Higher PSI capacity of 4400 for tough cleaning
- Stainless steel construction ensures durability
- Larger 16.5-inch cleaning path speeds up large-area cleaning
Cons:- Bulkier and heavier than smaller models, reducing maneuverability

Greenworks 12″ (in.) Surface Cleaner Pressure Washer Attachment
This Greenworks 12” surface cleaner is ideal for users with smaller pressure washers, such as the 1800 PSI Ryobi, and excels at gentle cleaning of patios and decks. It’s praised for its ability to clean without damaging delicate surfaces, unlike some larger attachments or high PSI pressure washers that can strip color or roughen surfaces. Compared to larger surface cleaners like Westinghouse’s stainless steel model, this one offers less coverage but greater control, making it suitable for detail-oriented tasks. Its compatibility with most 1/4-inch quick connect pressure washers simplifies setup. The 3-year warranty adds a layer of reliability. However, its smaller size means it takes longer to cover large areas, and it may not handle the most stubborn grime as effectively. Tradeoffs involve a smaller cleaning path for more precision and surface safety. This makes sense for homeowners who prioritize surface preservation and detailed cleaning over speed, but less so for large, tough jobs.
Pros:- Gentle on delicate surfaces, preserving color and texture
- Compatible with most 1/4-inch pressure washers
- Three-year warranty for peace of mind
Cons:- Limited coverage due to smaller 12-inch width
- Less effective on stubborn grime compared to larger or more powerful models

Compared with the Westinghouse 16.5” stainless steel model, this one offers a slightly smaller cleaning width but incorporates more accessories, including extension wands and multiple nozzles, for versatile cleaning. The splash-free skirt minimizes overspray, and the heavy-duty build prevents lift-off under high pressure. However, its weight and complexity might be overkill for casual users or small projects. Tradeoffs include a higher price point and additional accessories, but the durability and efficiency are unmatched for demanding jobs. This product suits contractors or serious DIYers with large, tough surfaces, but less so for occasional light-duty cleaning.
Pros:- Handles up to 4000 PSI for tough cleaning tasks
- Durable stainless steel housing and four wheels for mobility
- Includes multiple nozzles and extension wands for versatility
Cons:- Heavier and more complex to operate than smaller attachments

Factors to Consider When Choosing Best Pool Deck Pressure Washer Surface Cleaner
Choosing the best pool deck pressure washer surface cleaner requires understanding several key factors. While higher PSI and larger coverage areas might seem appealing, they are not always necessary for smaller decks or light cleaning. Considering ease of maneuverability and compatibility with your pressure washer ensures a smooth experience. Additionally, durability and maintenance needs can greatly affect long-term satisfaction. Here are the main factors to keep in mind before making a purchase.Power and PSI Ratings
Power is a primary concern when selecting a surface cleaner. Higher PSI ratings—around 3500 to 4500 PSI—enable effective removal of stubborn stains and dirt from concrete and stone surfaces. However, excessively high PSI can risk damaging delicate surfaces or your equipment if not compatible. Evaluate what your pressure washer can handle comfortably, and match it with a cleaner that provides enough force without overdoing it. Remember, a powerful cleaner is most beneficial if paired with a suitable pressure washer.
Size and Coverage Area
The size of the surface cleaner directly impacts how quickly you can complete your job. Larger models, like the 20-inch units, are ideal for expansive decks or driveways, reducing the number of passes needed. Smaller cleaners are more maneuverable but may take longer for extensive areas. Consider your typical cleaning scope and storage space—larger units can be cumbersome to handle and store but save time on big projects. Striking a balance between coverage and ease of handling is key.
Build Quality and Durability
Durability matters for frequent use. Look for stainless steel housings and heavy-duty wheels, which resist corrosion and withstand rough conditions. Cheaper plastic components may save money upfront but tend to wear out faster. A well-built cleaner with quality materials reduces replacement costs and keeps your deck looking good longer. Think about how often you’ll use it and whether investing in a sturdier model makes sense for your situation.
Ease of Use and Maneuverability
Design features like lightweight construction, smooth-rolling wheels, and ergonomic handles contribute to easier operation. Some models come with adjustable nozzles or extension wands, helping you reach difficult spots without strain. If you plan to use the cleaner frequently or on larger surfaces, choosing a model that minimizes fatigue will save time and effort. Conversely, smaller, simpler units might suffice for occasional use or smaller decks.
Compatibility and Attachments
Ensure the cleaner is compatible with your pressure washer’s PSI and connection type. Most models use a 1/4-inch quick connector, but verifying this prevents fitting issues. Some cleaners come with additional nozzles or extensions, broadening their application. Compatibility is especially critical if you own a less common pressure washer brand or model, as mismatched equipment can be unsafe or ineffective. Always double-check specifications before purchase.
Frequently Asked Questions
Can I use a surface cleaner on my wood deck?
While some surface cleaners are versatile enough for multiple surfaces, most are designed specifically for concrete, stone, or similar hard materials. Using a high-PSI cleaner on a wood deck may cause damage, such as splintering or gouging. For wood, it’s better to use a gentler approach, such as a low-pressure setting combined with a soft-bristle brush or a specialized wood cleaner. Always check the manufacturer guidelines to avoid accidental damage.
What size surface cleaner is best for my small pool deck?
For smaller decks, a compact cleaner—around 12 to 14 inches in diameter—provides sufficient coverage without being cumbersome. Smaller units are easier to maneuver in tight spaces and store after use. They may take longer to cover larger areas, so consider your typical project size. The key is to balance ease of handling with enough coverage to make the job efficient.
Will a higher PSI pressure washer damage my concrete patio?
It’s possible if the PSI exceeds the recommended limit for your surface, typically around 3000 PSI for concrete. Higher PSI can etch or erode the surface over time. Always verify your pressure washer’s PSI and match it with the cleaner’s specifications. Using a nozzle that reduces pressure or adjusting the flow rate can help prevent damage while still achieving a thorough clean.
Are there maintenance tips to extend the life of my surface cleaner?
Yes, regular cleaning of nozzles and brushes, inspecting wheels and seals, and avoiding harsh chemicals prolong the life of your cleaner. After each use, rinse off debris and check for wear or damage. Storing it in a dry, protected area prevents corrosion, especially if it has metal parts. Following the manufacturer’s maintenance recommendations ensures your cleaner remains effective over time.
Is it worth investing in a larger, more expensive surface cleaner?
Investing in a larger, higher-quality cleaner can save time and effort on big or frequent cleaning projects. While the initial cost is higher, the durability and efficiency of premium models often justify the expense. For occasional or small-area use, a more affordable, compact model might suffice. Consider your cleaning frequency and the size of your surfaces to determine if a premium investment makes sense.
Conclusion
For most homeowners, the Westinghouse 16.5” Surface Cleaner offers a great balance of power, size, and durability, making it the best overall pick. Those with larger areas or frequent cleaning needs might prefer the MEKOH 20” Surface Cleaner for its extensive coverage and high PSI. If budget is a priority, the Greenworks 12″ Surface Cleaner provides reliable performance at a lower cost, ideal for occasional use. Beginners or casual users should consider models with simpler controls and lighter weight, while professionals or heavy users should look at premium options with heavy-duty build quality. Matching your specific needs ensures you get the best results for your pool deck and outdoor surfaces.
