Bronner's castile soap is our favorite non-specialized product for surface cleaning indoor concrete floors. Dr. Bronner's is a nearly pH-neutral cleaner that comes in a variety of natural scents. Because the soap is concentrated, a few drops in a gallon of water is plenty.
Interior Concrete Floors:
Do Not use Dawn, Simple Green, Ammonia or harsh cleaners as they will work to damage and even strip the wax. The wax should last for several months or longer, but when it does start to dull or scuff, clean and let dry, then reapply a fresh coat of wax and let dry.
In fact, vinegar removes mold from concrete better than bleach. Bleach will only remove the top layer of mold, causing the mold to return.
You can use Simple Green Oxy Solve Concrete and Driveway Cleaner to clean a concrete patio with or without a pressure washer. It removes oil, grease, grime and most stains and discolorations. Its biodegradable formula is safe for lawns and pets.
Don't: Never use everyday floor cleaning products, such as Pine-Sol; always select a pH-neutral cleaner. Never use products such as ammonia, vinegar, bleach, muriatic acid, or other harsh cleaners on concrete floors.

Vinegar is an all-natural solution for cleaning concrete. It kills mildew and mold, removes grime, and helps treat set-in stains. Before cleaning concrete with vinegar, it's essential to dilute it so you don't affect your sealer.
It is exactly the same price per gallon, seems to offer better dilution ratios, and has a pH of 9.5 which is much less alkaline than Zep Citrus's 12.0 rating. Simple Green is approved for auto wheels, and even washing the entire vehicle at the correct ratios.
Simple Green Oxy Solve Concrete and Driveway Cleaner can be used with a pressure washer or for manual cleaning of concrete surfaces including driveways, sidewalks, patios, and walkways. The non-corrosive and non-degrading formula utilizes the natural power of peroxide to provide high-performance cleaning.
But that's not all; chlorine bleach can also be used for cleaning the concrete driveway. Of course, you should dilute it with equal parts of water or a 1:1 ratio. With the mixture ready, spray it on the driveway, allowing it to sit for 10 minutes. Then, use a stiff brush before rinsing with clean water.
As a gentler cleaner, bleach can't harm concrete's durable material. Aside from being an effective cleaner and stain remover, it also acts as a disinfectant to the concrete surface.
Pressure washing is one of the fastest, most effective ways to get your concrete white again. Concrete can change color over time due to pollen, algae, or dirt buildup, but a good pressure wash can easily remove dirt and stains and make your concrete look new again.
Use Concrete Sealer After Power Washing
It soaks up everything! An effective pressure wash cleans the pores of your concrete. Make sure to apply concrete sealer after pressure washing.
The Liquid peroxide cleans, refreshes, and brightens concrete, tile, and grout without leaving watermarks or residue in contrast to other cleaning chemicals.

Other possible side effects are:
Eye irritation. Skin irritation. Nausea.
