Simple Green Oxy Solve House Siding Cleaner
The Simple Green Oxy Solve House Siding Cleaner is a peroxide-based concentrate designed for exterior cleaning on multiple siding types. It targets tough stains and discoloration caused by algae, moss, mildew, and general grime. The formula uses peroxide power to lift embedded dirt without relying on harsh solvents, making it suitable for vinyl, aluminum, stucco, wood, and brick with proper dilution. This versatility is particularly helpful for homeowners who deal with seasonal mildew or after-storm algae growth on exterior walls.
When used as directed, the product can simplify large cleaning jobs by reducing the number of passes required to achieve a uniform appearance. It performs well on textured surfaces and can be diluted for lighter soils or high-traffic areas. Always test a small, inconspicuous area first and follow safety guidelines, including wearing eye protection and gloves. After cleaning, a thorough rinse helps prevent residue that could attract new dirt. This cleaner shines in projects that mix vinyl siding with other exterior materials in the same facade.

Simple Green Oxy Solve Total Outdoor Cleaner
The Total Outdoor Cleaner from Simple Green is a versatile, peroxide-powered detergent designed for a broad spectrum of outdoor surfaces. It excels at lifting dirt, grime, and stains from mold, mildew, moss, and algae across materials such as wood, composite, vinyl, metal, fabric, plastic, stone, brick, and concrete. The concentrated formula is intended for mixing with water in pressure washers, allowing homeowners to tailor strength to the job at hand. It’s particularly effective for large exterior cleaning projects, including decks, fences, and driveways that require thorough mold and algae removal.
In practical use, this product supports efficient cleaning workflows by covering extensive areas with a single dilution. The peroxide-based action helps drive deeper staining to the surface, reducing the need for aggressive scrubbing. As with any chemical cleaner, it’s important to protect surrounding plants and landscaping and to follow the manufacturer’s mixing ratios. Its multi-surface capability makes it a solid all-around option for soaking large exterior sections with consistent results.

Zep House And Siding Cleaner Concentrate
Zep’s House And Siding Cleaner Concentrate is a construction-grade formula designed for heavy-duty exterior cleaning. This concentrate is formulated to restore the look of vinyl, aluminum, and wood siding and is compatible with pressure washers to speed up large cleaning tasks. The product’s broad surface compatibility also includes hard coat stucco, brick, and cement types (such as Hardie Plank). It’s well-suited for property maintenance projects where a robust cleaner is needed to cut through months of built-up grime and environmental staining. Proper dilution is important to maximize efficiency and minimize surface impact.
Users typically apply this concentrate to pre-wet surfaces, allow a dwell time for the solution to penetrate grime, and then rinse thoroughly with a pressure washer. It’s designed to be used on exterior surfaces that face weather exposure and can dramatically improve curb appeal with repeated application. As with other industrial-grade cleaners, wear eye protection and gloves, and scout-test on an inconspicuous area before broader use to avoid any unexpected changes in color or finish.
- Restores vinyl, aluminum, and wood siding
- Safe for use on stucco, brick, and cement surfaces
- Pressure washer compatible for fast cleaning on large areas
BEEST Vinyl Siding Cleaner
BEEST Vinyl Siding Cleaner is an ultra-concentrated formula designed to be economical for large exterior cleaning tasks. It promises to restore a “green” or weathered look by removing dirt, grime, and airborne algae from vinyl siding, fences, and other outdoor surfaces. A notable feature is its high yield: the product makes up to 26 gallons of cleaner from a single gallon, making it a cost-effective option for sizeable homes or multi-building properties. It’s marketed as a multi-surface cleaner, expanding its usefulness beyond vinyl to stone, plastics, and painted surfaces, which can be convenient for mixed-material exteriors.
For best results, BEEST recommends pre-wetting surfaces, applying the concentrate, allowing dwell time for soils to loosen, and thoroughly rinsing. The strong concentration means lighter soils may only require partial dilution, while heavy staining calls for stronger mixes. As with any strong cleaner, ensure proper ventilation and protect plants and adjacent surfaces during application. This product is ideal for homeowners who want significant cleaning power and a broad surface range without purchasing multiple cleaners.
- Ultra-concentrated; up to 26 gallons of cleaner per bottle
- Multi-surface versatility: vinyl, stone, concrete, plastics
- Restores exterior cleanliness and curb appeal
30 SECONDS Foam Cannon Kit
The 30 SECONDS Foam Cannon Kit brings a foaming solution to exterior cleaning with a dedicated foam cannon and cleaning soap. The kit emphasizes heavy foam action that clings to siding, decks, driveways, and other outdoor surfaces, enabling dirt to loosen on contact. The soap is designed to be gentle on surfaces while still delivering effective cleaning, making it suitable for vinyl siding, wood decks, and concrete driveways. The control features allow adjusting foam output and spray width, giving users the ability to tailor the cleaning action to the surface being treated and to switch to a rinse mode when the foam has done its job.
Foam cleaning can reduce scrubbing time and minimize water run-off. It’s particularly helpful for routine maintenance on large homes or properties with multiple exterior surfaces. As always, test on a small area first and follow the manufacturer’s dilution guidance. When paired with a compatible pressure washer, this kit can provide a convenient, all-in-one approach to siding and outdoor surface care.
- Powerful foaming action for quick dirt loosening
- Safe to use on siding, decks, and driveways
- Adjustable foam output and rinse mode for versatile cleaning
Buying Guide
When selecting a siding cleaner for a pressure washer, consider surface type, soil level, and the desired balance between convenience and cleaning power. Concentrates generally offer greater value per gallon and allow you to tailor strength to the job, but ready-to-use formulas may be easier for casual, smaller projects. Peroxide-based cleaners excel at lifting mold, mildew, and algae from exterior surfaces, yet you should follow dilution guidelines to avoid discoloration or damage on sensitive finishes.
Surface compatibility is a critical factor. Vinyl siding benefits from gentle, peroxide-based cleaners that remove surface staining without etching. Wood requires products that prevent raised grain or warp, especially on pressure-washed applications. Brick and concrete substrates can tolerate stronger formulations but still demand proper rinsing to prevent residue and staining. For large-scale cleaning, concentrated products paired with a foam cannon can save time and water, but ensure your equipment is compatible and the spray pattern suits the area being treated.
Application method matters. Some products are designed for direct spray, others for soak-and-rinse workflows. Always pre-wet surfaces, follow dwell times recommended by the manufacturer, and rinse thoroughly with a pressure washer. Testing a small area first helps verify colorfastness and finish integrity. Environmental considerations include protecting landscaping and using the minimum effective dilution to reduce chemical runoff. Finally, consider packaging size and yield: ultra-concentrates can be economical for multiple exterior projects but require careful handling and storage.
Quick comparison by surface type
- Vinyl siding: Look for peroxide-based concentrates that lift surface stains without harsh bleaching.
