Simple Green Oxy Solve Total Outdoor Cleaner -- Best All-Rounder
Simple Green Oxy Solve is the most versatile formula on this list. It handles concrete driveways, patios, walkways, garage floors, and even outdoor furniture and siding. The oxygen-activated chemistry lifts dirt, oil, mildew, algae, and general grime effectively, and it works with both pressure washers and manual scrubbing. The biodegradable formula is safe for plants after rinsing, making it ideal for mixed outdoor environments. The concentrated solution offers excellent value per use, and the scent is mild. For homeowners who want a single product that covers most concrete cleaning needs without swapping formulas, this is the most practical choice.
Wet & Forget Outdoor Cleaner -- Best No-Scrub Option
Wet & Forget takes a completely different approach: apply it, then walk away. The formula works with rainfall and ambient moisture over days and weeks to gradually remove algae, lichen, mold, and mildew from concrete and other outdoor surfaces. It requires zero scrubbing and no rinsing. The trade-off is time -- results become visible after the first few rainfall events, with full effect over two to four weeks. For homeowners with large patio areas or concrete paths they want to clean with minimal effort, Wet & Forget delivers impressive long-term results. Reapply annually for ongoing prevention.
Spray & Forget notable Roof Cleaner -- Best for Mold and Algae
Spray & Forget is primarily marketed for roofs but works exceptionally well on concrete surfaces with chronic mold and algae issues, particularly patios and basement entries with limited sun exposure. The biocide formula kills the biological growth at the root and inhibits regrowth for up to a year. Apply on a dry day, do not rinse, and let rain do the follow-up work. It is safe for pets once dry, which is a meaningful advantage over bleach-based alternatives. For shaded concrete areas that continuously struggle with biological growth, this is a more targeted solution than general-purpose cleaners.
Zep Concrete & Masonry Cleaner -- Best Budget Concentrate
Zep's flagship concrete formula is one of the most trusted professional-grade products available at consumer prices. The high-alkalinity concentrate handles oil, grease, dirt, tire marks, and general weathering stains on both sealed and unsealed concrete. At the standard dilution it is suitable for routine cleaning; at higher concentrations it tackles years of buildup. The gallon format delivers the best cost-per-use of any product on this list. Compatible with mops, buckets, and pressure washer tanks. For budget-conscious homeowners who want reliable performance across a variety of concrete stain types, Zep sets the standard.
Black Diamond Stoneworks Ultimate Cleaner -- Best for Indoor and Decorative Conc
Most concrete cleaners are formulated for rough exterior surfaces and can be too aggressive for polished, stained, or decorative interior concrete. Black Diamond Stoneworks is pH-neutral, making it safe for finished floors, countertops, and sealed surfaces without stripping the sealer or dulling the finish. It removes everyday grime, food, and grease from interior concrete with no residue. The ready-to-use spray bottle format makes it convenient for spot cleaning. For homeowners with concrete kitchen countertops, polished basement floors, or decorative garage flooring, this is the only product on this list that will not risk the finish.
How to choose
What to consider
Start by identifying your primary use case. Outdoor surfaces with organic staining (algae, mold, general dirt) benefit most from oxygen-based or biocide formulas. Indoor and decorative surfaces need pH-neutral products. Heavy oil and grease require alkaline chemistry. Volume matters too: a gallon concentrate is more economical for large driveways than a ready-to-use spray bottle. Finally, consider frequency -- some solutions like Wet & Forget are designed for annual application, while others require seasonal reapplication. A good sealer applied after cleaning extends the time between treatments for any product.

Common questions
A concrete cleaner is a broad term covering any formula that removes dirt, stains, or growth from concrete. A degreaser specifically targets oil and grease using alkaline chemistry or solvents that break hydrocarbon bonds. Most good concrete cleaners double as degreasers at higher concentrations, but products marketed only as degreasers may not handle biological stains like mold or efflorescence as effectively.
It depends on the formula. Bleach-based and muriatic acid products will damage plants on contact. Oxygen-based and enzyme-based formulas are generally biodegradable and safe once diluted and rinsed, but you should still avoid direct contact with plant roots or foliage during application. When cleaning near garden beds, pre-wet surrounding soil before application and rinse immediately toward a drain rather than into the garden.
