The best pressure washer detergents for patios compared, concentrates that run through a washer to lift grime and oil from paving, by dilution and chemistry.
By Gardening Is Ezee Editors
7 min read5 products evaluated
Running plain water through a pressure washer blasts loose dirt but leaves algae film and oil behind. A detergent drawn through the washer or pre-sprayed does the chemical work so the water just rinses. We compared five current pressure washer detergents for patios on dilution, coverage, and what each formula targets.

How We Built This Shortlist
Each pick was assessed across 3 criteria weighted for real-world use.

What Matters Before You Choose a Pressure Washer Detergent for Patios (2026)
Key buying criteria so you get the right fit the first time.
Washer Compatibility
Not every detergent is safe to draw through every pressure washer's injector, and some are labeled for a specific brand. Kärcher's multi-purpose formula explicitly works with most consumer machines. Check your washer's manual for approved detergent types before you fill the tank.
Using the wrong detergent can clog or corrode the injector.
Dilution Ratio
These range from Kärcher's one gallon makes forty down to formulas closer to one to five. The higher the ratio, the more patio a bottle cleans and the lower the real cost. A dedicated degreaser at a lower ratio can still be worth it for stubborn oil.
Compare cost per gallon of mixed detergent, not per bottle.
Surface: Masonry vs. Wood
A concrete-and-driveway detergent is built for hard mineral surfaces and can be harsh on wood. A multi-surface formula like Oxy Solve Total is rated for decking too. If your patio is timber or composite, do not use a concrete-specific product on it.
Match the detergent to the softest surface you will spray.
Match a Pressure Washer Detergent for Patios (2026) to Your Garden or Yard
By Priority
| Priority | Recommended Pick |
|---|---|
| Paved patio with oil and tire marks | Simple Green Oxy Solve Concrete and Driveway |
| Lowest cost per clean | Kärcher Multi-Purpose Detergent |
| Years of built-up grime | Krud Kutter Multi-Purpose Concentrate |
| Patio plus deck and siding | Simple Green Oxy Solve Total |
| Whole-house single session | Zep All-in-1 172oz Concentrate |
By Budget
| Budget | Recommended Pick |
|---|---|
| Lowest cost per mixed gallon | Kärcher Multi-Purpose or Krud Kutter |
| Mid-range | Zep All-in-1 or Simple Green Concrete and Driveway |
| Larger outlay | Simple Green Oxy Solve Total |
Concrete-Specific vs. Multi-Surface: The Verdict
The softest surface you will spray decides this.
- Choose concrete-specific if
- Your patio is entirely paving, masonry, or driveway, like Simple Green Oxy Solve Concrete and Driveway.
- Choose multi-surface if
- You will also spray timber or composite decking and a fence, like Oxy Solve Total.
For a Patio With Heavy Oil Staining Specifically
- Look for
- A commercial-strength penetrating degreaser with a stated dwell time, not a general algae cleaner.
- In this comparison
- Krud Kutter Multi-Purpose penetrates oil and grease over a three to five minute dwell.
Before You Bring One Home
Do I need a special detergent for a pressure washer?
Yes. Household cleaners can foam excessively, clog the detergent injector, or damage seals. Use a product labeled for pressure washers, and check your machine's manual for the detergent types it approves before drawing anything through the low-pressure siphon.
Can I use pressure washer detergent without a pressure washer?
Most of these can also be applied with a pump sprayer or watering can, left to dwell, and rinsed with a hose. Kärcher's and Krud Kutter's labels both allow manual use. You lose some cleaning speed but the chemistry still works.
Is a concrete detergent safe on a wood deck?
Not necessarily. Concrete and driveway formulas are built for hard mineral surfaces and can be harsh on timber or composite. If your patio area includes decking, choose a multi-surface formula like Simple Green Oxy Solve Total that is rated for wood.
How much detergent do I need for a patio?
Measure the area, then check the coverage figure for the diluted product. A highly concentrated detergent like Kärcher's, at one gallon makes forty, covers a large patio several times over. A lower-dilution degreaser covers less but hits tougher stains harder.
