Ironite is an acid-soluble metallic salt, which means that when it comes in contact with water or acid, it creates a liquid that imparts a permanent stain. Although this stain will not color everything and is not uniform in shade or transparency, it does provide a lovely mottled earthy brown stain to concrete. It is advisable that you perform a trial in an inconspicuous area to ensure that you actually appreciate the color it yields.
Ensure that the concrete is extremely clean and free of any debris. Wash the concrete area with a mixture of trisodium phosphate and water, mixed according to the manufacturer's directions, and scrub with a stiff broom. Rinse the concrete thoroughly with water to remove all traces of the cleaner.
Broadcast handfuls of ironite across the concrete surface. You can use a systematic or a random approach, but keep in mind that each place a granule of ironite lands will be colored a deep, earthy brown. Small puddles of water standing on the concrete will disperse the ironite, causing a lighter shade of stain. Allow the concrete to dry thoroughly.
Repeat the above process if the stain is not dark enough or if you want a more uniform color. Each subsequent layer of stain will darken the surface of the concrete. Make sure you allow the concrete to dry for at least six hours between applications of water and ironite.
Dissolve 1 lb. of baking soda in 5 gallons of warm water the day after you apply the ironite. Rinse the stained concrete area with the baking soda solution to remove excess stain. The baking soda solution halts the staining process so that the surface will not fade with exposure to water or rain.
Spread a layer of kitty litter, cornstarch, sawdust or baking soda over the grease stains. Use enough of your chosen material to thoroughly cover the grease stain. Allow the material to absorb the grease or oil for three hours.
Use a stiff nylon brush and scrub the kitty litter, cornstarch, sawdust or baking soda into the stain. Scrub the area in different directions to push the material into the stain and the concrete crevices. The will allow the material to soak up more of the grease. If the surface is large with multiple stains, such as a driveway, use a push broom with hard, rough bristles.
Sweep the area thoroughly and throw away the material used to absorb the grease. Prepare soapy water using 1/4 cup dish soap to 1 gallon of hot water. Scrub the stained area in the same manner as step 2. The amount of soapy water needed will vary by the size of the stain and how much of the grease remains. Rinse the area with plain water.
Allow the area to dry. Repeat the process until the stain is removed. Grease stains more than a year old or areas where the grease has built up over months may require multiple treatments.
Mix 2 gallons of water with 6 oz. of dishwashing detergent.
Scrub the stains using the scrub brush and detergent mixture, which will break up dirt, grease and plant oils. Scrub until the stains resist further scrubbing. Make sure to wear your rubber gloves.
Mix 2 gallons of water with 4 oz. of bleach.
Scrub the remaining stains with the bleach mixture, which will remove most of the remaining black or green colors from the concrete.
Power-wash any remaining stains and cracks with a power washer of at least 750 pounds per square inch (psi). The power washer will remove loosened particles from cracks or pores in the concrete.
Pour cornmeal over the grease stain on the concrete. Use enough to completely cover the stain and leave it there for 20 minutes to absorb excess oil. Repeat if more grease remains, then sweep up with a broom and dustpan.
Combine 1 oz. trisodium phosphate with 1 cup warm water in a bucket. Add 1 cup baking soda. Put on rubber gloves and goggles, then mix the ingredients with a paint stirrer.
Spread the mixture over the remaining grease stain with a scraper. Leave the paste on your concrete surface until it dries. As the mixture dries, it will draw the grease stain out of the concrete.
Scrape up the dried trisodium phosphate paste and throw it away. Wet a nylon scrub brush and pour a few drops of dishwashing detergent onto the scrub brush. Scrub the site of the grease stain on your concrete surface with the soapy brush.
Pour water over the concrete to rinse off the soap suds. Towel dry your concrete surface. Allow it to air dry completely.
Water Based Concrete Stains
The ideal temperature for applying water-based concrete stain is 70 degrees Fahrenheit. You can apply the stain in temperatures as low as 45 degrees, but lower temperatures can cause slower drying time. The temperature can be as high as 90 degrees for stain application, but higher temperatures can prevent the stain from penetrating the concrete well.
Acid-Based Concrete Stains
Acid-based concrete stain should be applied when the concrete temperature is between 59 and 70 degrees Fahrenheit. The staining process will experience similar issues to water-based stains if the temperature is too high or too low.
Other Environmental Factors
High humidity can slow the drying time for concrete stains significantly. Windy conditions can cause the stain to dry too quickly and not penetrate the concrete well. Make sure the concrete is thoroughly cleaned and dried before staining and allow the work to cure for 24 to 48 hours before sealing.
Apply a vitamin C tablet directly on the stain. If the stain is due to metal, it should lift up quickly. Scrub the affected area with a soft bristled brush to work out the stain.
Apply ascorbic acid powder to your pool filter, according to the manufacturer's specifications. This is helpful if several stains are spread across the entire pool.
Scrape a chlorine tablet over the stained area to bleach out the stain. Scrub the area with a soft bristled brush to aid in the stain removal.
Put on a long-sleeved shirt, long pants and gloves to protect your skin. Put on plastic goggles to protect your eyes and a face mask to protect your respiratory system.
Pour 1/2 cup of trisodium phosphate into a bucket. Run the faucet until the water runs hot. Then fill the bucket with 1/2 gallon of water.
Pour the solution directly onto the urine stain. Let it break down the acid crystals in the urine for about 20 minutes.
Scrub the stain with a hard-bristled brush. Rinse the residue with water.
Repeat the cleaning process, if necessary, until the stain is gone.
Drain the pool and put on your gloves and goggles. The trisodium phosphate, strong base cleaner, can burn your eyes and should always be diluted with water. Put on your protective gear before opening the trisodium bottle.
Create the trisodium and water mixture by mixing 1 cup of water and only 1 ounce of trisodium phosphate. Mix with a wooden dowel. Even with gloves on, do not use your hands to stir it. The consistency should be pasty like cement.
Apply a layer about 3/8 inch thick across each leaf-stained area. Use the trowel or paint scraper to spread it over the stains. The trisodium phosphate will penetrate the stain and break up its components.
Allow the paste to dry for 24 hours and then use the paint scraper to remove the hardened mixture. Remove any stuck-on pieces with the nylon brush.
Hose the areas down and then rub the pumice stone on each leaf stain that remains.
Removing Tannins from a Concrete Patio
Hose down the patio. You can use a pressure nozzle in order to clean away any detritus or contamination that may be resting on the concrete surface.
Mix the wood brightener. I know it sounds strange to be using "wood brightener" on concrete, but what you are really looking for is the active ingredient "oxalic acid." Oxalic acid is a mild acid that neutralizes the tannins in redwood. Wood brightener is typically concentrated. Mix it according to the manufacturer's instructions.
Apply the brightener. You can use your nylon brush to spread the brightener over the concrete surface. Apply the brightener to wet concrete. This will help to keep the oxalic acid working. If the brightener is allowed to dry, it will become inert. Misting the concrete will reactivate the brightener.
Allow the brightener to sit for 15 to 30 minutes, then scrub the concrete thoroughly with your nylon brush.
Rinse the concrete. Hose it down with your pressure hose again. If the concrete is still dark, repeat the process. You can leave the brightener on longer if necessary.
Removing oil stains
Soak up as much oil as possible with a rag as soon as you notice the spill. Use a blotting technique. Do not smear or rub the oil into the concrete.
Scrub the affected area with dish soap and a scrubbing brush. Rinse the area with water. Repeat scrubbing if necessary. Rinse with water.
Apply a degreaser to the affected area if the stain remains.
Removing grease stains
Blot the affected area with a rag immediately following a spill.
Mix hot water in a bucket with dish soap.
Scrub the affected area with the hot soapy water and a scrubbing sponge until removed. Rinse with water.
Remove old coating or sealer using a concrete paint stripper product. Follow the manufacturer's instructions.
Clean the surface thoroughly, using a concrete cleaner and scrub brush or power washer. Remove all stains, grease and oil.
Apply a concrete etcher to open the pores so the concrete can better absorb the stain. Follow the manufacturer's instructions.
Apply a concrete bonding primer to improve the adhesion of the stain. Follow the manufacturer's instructions.
Mix the stain thoroughly; pour it into the sprayer. Set the sprayer to the fine spray position.
Spray a thin layer of stain in 4-by-4-foot sections, using the sprayer in a circular motion. Proceed quickly; feather the edges.
Back-roll each area immediately after spraying, using the 3/8-inch nap roller or pad applicator.
Allow the stain to cure for 4 hours before applying a second coat for even coverage over the entire area.
Apply a top coat of a clear seal or high gloss wax to protect the stain and add a glossy finish. Follow the manufacturer's instructions.
Oil spills are the most common driveway stain. Cover the spill with a single layer of clean cat litter and rub the litter into the stain with a broom.
After you can see that the litter has soaked up much of the spill, sweep up the litter and discard it in the trash.
Reapply a layer of clean cat litter on the remaining stain and leave it to sit for a day. Sweep up and discard litter.
Clean the stained area with soap and water.
If there is a paint stain in the driveway, get a product called Lift Off. There are several different varieties of Lift Off for the different kinds of stains. Lift Off 4 removes spray paint and Lift Off 5 removes latex paints. The process for both is the same. They cost less than $10 a bottle.
Saturate the painted area with Lift Off and let it sit for at least 3 minutes.
Rub in product with an old broom.
Hose or power wash the area. If the stain persists, repeated treatments may be necessary.
Clean up any fresh oil stains by blotting the surface with newspaper.
Pour a generous amount of liquid laundry detergent onto the stain so that it covers its entire surface.
Allow the detergent to settle for five minutes, then scrub the detergent into the stain with a stiff-bristled brush, using short, circular movements.
Rinse the oil and detergent from the concrete by spraying it down with a garden house. If the stain is still present, repeat the process.
Pour some vegetable oil directly on your palms. Other oils will also help remove the stain, but vegetable oil is recommended because it is readily available in most people's homes, and it is all-natural.
Rub your hands together, working the oil over the entire surface of your hands.
Take a paper towel and begin dabbing off the oil. Dabbing keeps the mess from spreading; if you rub the oil, you may accidentally smear some of the black walnut stain back into a clean area of your hand. Keep dabbing until you've sopped up most the oil and stain.
Run your hands under water to wash off the remaining oil and stain. Use an outdoor hose, since it is possible for the washed-off stain to discolor your sink.
Inspect your hands; if you still have a lot of stain on your skin, repeat Steps 1 through 4.
Wash your hands with soap and water to remove any leftover oily residue after you're sure all the stain has been removed.
Prepare the Boxes for Staining
Clean the boxes with a good wood cleaning product. Use the nylon scrub brush to remove any grime or contamination from the wood's surface.
If the wood darkens during the cleaning process, use a wood brightening product containing oxalic acid as the active ingredient. Oxalic acid neutralizes dark, staining tannins that are prevalent in certain types of wood. Redwood and cedar both tend to contain high levels of tannin. Tannin stains are sometimes confused with mildew. You often see them streaking from nail holes on a cedar fence.
After the wood is cleaned and brightened, allow it to dry for 24 hours prior to staining.
Apply the Stain
Once the wood is clean and dry, you are ready to stain. Lay down a dropcloth or some newspapers to avoid staining the surface you are working on. Also, wear some crummy old clothes you're not too worried about.
Use a paint brush to apply the stain. Work in the direction of the wood's grain, and maintain a wet edge.
As you work, feed the wood as much stain as it will absorb.
After the boxes are stained, wait for about 30 minutes. Then, take a dry paint brush and remove any excess stain that has not completely soaked into the wood's surface. Penetrating stains will not dry hard, but stain that is allowed to remain on the surface of the wood can become sticky and cause problems.
Gather liquid dish soap, a scrub brush and a bucket of water. Pour some liquid dish soap on the stain. Add water to the dish soap. Wet down the concrete surrounding the stain, also. This prevents any oil released during the cleaning process from causing a second stain.
Scrub the stain with the brush forcefully. Add enough water to create a rich lather over the stain. When the liquid soap mixes with the oil, it will loosen the stain from the concrete. Once the oil stain is removed, do not rinse the excess oil and water off the driveway. This will pollute your yard or neighborhood.
Blot up the mixture from the concrete with paper towels or kitty litter. Dispose of it in a landfill certified for this type of environmental hazard. Talk to your waste collection service to see if it can help you with the disposal.
Pour a solvent, such as kerosene, on the old stain if you are not satisfied with the results from using liquid dish soap. But keep in mind that solvents are flammable, and take proper precautions. If decide that using kerosene is necessary, consult with your fire department for safety tips.
