Concrete surfaces – driveways, floors, patios etc – are durable and versatile. But being porous they can get stained by various substances – oil, grease, rust, organic matter etc. These stains can be tough to remove and if left untreated can cause long term damage. This guide will show you how to tackle tough stains on concrete surfaces with professional cement cleaning service.
Types of Concrete Stains
- Oil Stains:
Oil stains are common on concrete driveways and garage floors, usually from spilled car fluids. These stains can penetrate deep into the surface and are tough to remove. - Grease Stains:
Like oil stains, grease stains are found in commercial kitchens or industrial areas. They are even tougher due to their thick and sticky nature. - Rust Stains:
Rust stains occur when metal objects or structures like rebar corrode and leach iron onto the concrete surface. These are orange-brown in color and are hard to remove. - Organic Stains:
Organic stains are from food spills, soil, plant matter, other natural substances. These can attract mold and mildew if not treated ASAP. - Mildew and Mold Stains:
Found in damp areas like concrete patios and basements, mildew and mold stains are from excessive moisture. They create black or green patches on the surface. - Rust Stains:
Rust stains are orange-brown in color and are from metal items like rebar corroding over time. Needs specialized treatment to lift the iron deposits from the concrete.
Cement Cleaning Techniques
- Surface Preparation
- Remove Loose Debris:
Start by clearing the concrete surface of loose dirt, leaves and debris. Use a broom or a vacuum to clean the surface and remove any obstructions. - Assess the Stain:
Determine the type and extent of the stain. This will help you choose the right cleaning solution and method.
- Choose the Right Cleaning Solution
- Chemical Cleaners:
- For Oil and Grease Stains: Specialized degreasers or commercial stain removers are needed. Products with solvents or surfactants can break down the oils and fats.
- For Rust Stains: Rust removers or phosphoric acid can be used. Phosphoric acid reacts with iron to lift the stain from the concrete.
- For Organic Stains: Mildew removers or bleach solutions are effective. Use these in a well ventilated area to avoid respiratory issues.
- Non-Chemical Solutions:
- For lighter Scratches, warm water and mild dish soap can work. Baking soda and vinegar are natural alternatives for some stains.
- DIY Solutions: Simple solutions like laundry detergent and warm water can work for some stains.
- Pressure Washing and Power Washing
- Using Pressure Washers:
Pressure washers are good for deep seated stains. Adjust the pressure to not damage the concrete. For larger areas like driveways and patios a pressure washer can clean fast and efficient. - Water Temperature:
Hot water dissolves grease and other tough stains better than cold water. Make sure you use clean water throughout the process, not to add contaminants.
- Scrubbing and Brushing
- Manual Scrubbing:
Use a scrub brush or stiff brush to work the cleaning solution into the concrete. For light stains a soft brush will do, for tougher stains a more abrasive brush. - Using a Spray Bottle:
Apply the cleaning solution evenly with a spray bottle. Let it sit for a few minutes to loosen the stains before scrubbing.
- Post-Cleaning
- Rinsing:
Rinse the surface with clean water to remove any leftover cleaning solution. For large areas a garden hose or high pressure water stream will do. - Sealing and Protection:
After cleaning, apply a concrete sealer to protect the surface from future stains. Sealers create a barrier that prevents stains from penetrating and makes future cleaning easier. - Maintenance:
Regular cleaning and maintenance will prevent tough stains from building up. Schedule regular cleanings and address spills as they happen to keep your concrete surfaces looking good.
- Advanced Techniques for Severe Stains
- Chemical Strippers:
Professional grade chemical strippers for extremely tough stains. These products will break down and remove tough stains. - Deep Cleaning Methods:
Professionals may use advanced cleaning technologies like rotary scrubbers and specialized extraction equipment to get a deeper clean. - Surface Repair:
If the stain has caused surface damage, concrete resurfacing or patching may be required. This will restore the surface to its original state.
