Outdoor MAX vs. Outdoor Spaces: Maximizing the Clean of Your Outdoor Spaces

By Wet & Forget

Most homeowners want their outdoor spaces to look clean and well cared for. A tidy patio, a clean driveway, or fresh-looking siding can change how your whole home feels. The challenge is knowing what to use and when, especially when outdoor surfaces start to show wear from the elements. Green and black stains can slowly appear on areas exposed to moisture and shade. These marks can make patios, concrete, and exterior surfaces look older than they really are. When that happens, many homeowners start looking for an outdoor cleaner that fits their space and their comfort level.

The Quick Answer

Wet & Forget offers outdoor cleaning solutions designed for different needs: Outdoor MAX and Outdoor Spaces. Both use the same bleach-free, color-safe formula, one-step application but they are built for different types of projects. This guide can help you decide which one makes the most sense for your home.

Use Outdoor MAX for:

  • Large areas like roofs & driveways
  • Heavier buildup
  • Higher or hard-to-reach surfaces like second story siding
  • Bigger seasonal projects

 Use Outdoor Spaces for:

  • Everyday outdoor living areas such as garden borders and patios
  • Smaller, ground-level projects like walkways and porches
  • Routine upkeep
  • Quick refreshes around the home like patio cushions and planters

What is Wet & Forget Outdoor MAX?

Wet & Forget Outdoor MAX is designed for larger outdoor cleaning projects and bigger surfaces. It is the same powerful formula customers have trusted for years, now rebranded with a new name and updated label. The application methods, bottles, and sprayers remain the same. It is used to treat moss, mold, mildew and algae stains that develop over time on exterior surfaces where moisture usually tends to linger. Many homeowners choose Outdoor MAX when they want an outdoor cleaner that can cover more area and reach higher elevations.

How both products work

Both Outdoor MAX and Outdoor Spaces work gradually with time and weather. After application, the formula begins to break down unwanted growths on outdoor surfaces. Wind and rain help clean black and green stains over time. Green stains usually clean up in a few weeks. Black stains clean up in a few months. There is no scrubbing, rinsing, or power washing required. This makes both options appealing for homeowners who prefer a lower-effort approach to outdoor cleaning projects.

Can you use both?

Yes, and many homeowners do! Both products use the same core formula, so they are often used interchangeably depending on the situation. Some people keep Outdoor MAX for larger areas and Outdoor Spaces for everyday maintenance. In most cases, the decision comes down to the size of the project and how you prefer to apply it rather than differences in the formula. Many homeowners simply reach for the one that best fits the job they are working on.
