Pretreating a surface before pressure washing offers several important benefits:

Pre-Treatment Benefits

• Breaks down dirt and grime – Cleaning solutions loosen embedded dirt, grease, and organic buildup so they rinse away more easily.

• Kills mold, mildew, algae, and bacteria – Pretreatment eliminates organic growth instead of simply blasting it off, helping prevent rapid regrowth.

• Produces a cleaner finish – Stains, black streaks, and green algae are removed more evenly, leaving a brighter, more uniform appearance.

• Reduces the need for high pressure – Since the cleaning solution does much of the work, lower pressure can be used, reducing the risk of damaging concrete, siding, wood, or painted surfaces.

• Saves time and labor – Less wand time and fewer repeat passes are needed, making the cleaning process more efficient.

• Improves the effectiveness of post-treatment – On surfaces like concrete, pretreatment followed by a post-treatment helps eliminate remaining spores and extends the clean appearance.

• Extends the life of exterior surfaces – Removing harmful organic growth helps prevent premature deterioration and staining.
