3 Criteria to Look For Before Buying a Patio Cleaners (2026)
Key buying criteria so you get the right fit the first time.
Fast Oxidizer vs. Slow Weather Treatment
Oxidizing sprays like Home Armor and 30 SECONDS lift stains in minutes but need a rinse and sometimes a second pass. Slow treatments like Wet & Forget take one to two weeks on green stains and months on black, but need no scrubbing or rinsing at all.
Event this weekend, buy the oxidizer; ongoing upkeep, buy the slow treatment.
Coverage vs. What You Are Cleaning
Concentrates rate coverage after dilution, and it varies widely: Simple Green Oxy Solve claims up to 6,400 square feet, a ready-to-use trigger bottle far less. Measure your patio and add the fence and steps.
Buying a ready sprayer for a big patio means going back to the store.
Plant and Surface Safety
Most of these are plant safe only when you wet the beds first and rinse after, and several warn against new cedar, redwood, or metal. A peroxide or EPA Safer Choice formula lowers the run-off worry near vegetable beds.
Read the surface exclusions before spraying anything near a deck stain or planter.

Frequently Asked Questions
How do patio cleaners actually remove algae and mold?
Fast cleaners oxidize the organic growth so it loses its grip and rinses away, which is why they show results in minutes. Slow treatments like Wet & Forget kill the growth and then let wind and rain wash it off gradually over one to several weeks depending on the stain.
Do I still need to scrub after using a patio cleaner?
With the fast oxidizing sprays, usually a light rinse is enough and heavy patches may want one more pass. With the slow weather-driven treatments there is no scrubbing at all. A stiff deck brush helps on ingrained black spots regardless of the product.
Are patio cleaners safe for nearby plants?
Most are labeled plant safe only when used as directed, which means wetting the surrounding beds and lawn before you spray and rinsing them after. Peroxide-based and EPA Safer Choice formulas lower the risk further. Never let concentrated product pool on soil.
How much patio cleaner do I need?
Measure the paved area plus any fence, steps, and walls, then check the product's coverage after dilution. Concentrates like Simple Green Oxy Solve cover thousands of square feet; a ready-to-use trigger bottle covers far less and is really for spot cleaning.
