Steps To Remove Minor Rust Stains From Concrete With Pressure Washer

Be sure first of the concrete surface you will be dealing with before going with the rust treatment. The acid-treated and painted concrete surface is delicate. It is also susceptible to more acidic cleaning essentials. It is good to dilute cleaning solutions to a soft and painted concrete surface. Use only 1-part of the cleaning solution to 1-part of the water ratio. Then, prepare the materials needed as water, liquid detergent, rubber gloves, vinegar or pure lemon juice, safety glasses, & a pressure washer. Anyway, how to remove rust stains from concrete with pressure washer:


Step #1. Cleaning the concrete surface with water and soap

Get rid of the rust stains from concrete with water and soap. Remove the grease or dirt from the surface. Thick grime and dirt can remove the acids as they penetrate the concrete surface. Thus, it eventually pulls the rust stain.


Step #2. Rinsing off the solution

Rinse the soapy solution to the rust stains from the concrete surface. And then, use cleaner water after. Next, get rid of the soap traces from the concrete surface.


Step #3. Applying lemon juice

Apply the lemon juice undiluted over the rust stains. Lemon juice makes a powerful and excellent removal solution for stains.


Step #4. Soaking the concrete surface with lemon juice

Soak the concrete surface with rust stains with lemon juice. Allow the liquid to sit for ten to fifteen minutes. Allow the lemon juice as it steeps for fifteen minutes and penetrates the area intensely. It then reacts with the stain.


Step #5. Rinsing the acid with pressure washer

Use a pressure washer when rinsing the acid from the concrete surface. This device is a great alternative when you scrub the surface. Select the correct nozzle of the pressure washer. Opt for a zero or fifteen-degree nozzle for a forceful and robust spray. A lower pressure washer type of nozzle brings out a firmer and more pointed spray.


Step #6. Rinsing the rust stains

Rinse the rusted area & let it dry. If it still has a persisting stain, follow a similar process.


Step #7. Replace white vinegar with lemon juice

It does keep it from turning the surface blue. And, follow all the safety warnings on the bottle label because acids are corrosive. Wear some protective gear. Prepare the materials like a pressure washer, rubber gloves, safety glasses, water, soap, commercial rust remover, long pants, & long-sleeved shirts.

Step #2. Cleaning the concrete surface with water and soap

Rinse the area stained with rust with water. Allow it to dry. Never apply a commercial type of rust cleaner to the wet spot. Or else, it may just lower its efficacy rate. Better to read the instructions label.


Step #4. Applying rust remover

Apply the rust stain remover onto the affected concrete area. Read the safety instructions and the directions on the bottle.


Step #5. Allow the rust stain remover to sit still

Allow the rust stain remover or acid to stay still for a while. Never attempt to allow the mixture to last longer, or it may damage the concrete surface.


Step #6. Rinsing using a pressure washer

Rinse the concrete with a pressure washer after the steeping time completes. The pressure washer has an eighty-time pressure of the hose pipe, making it effective instead of a scrubbing brush. Now, this washer deals with rust stains more effectively on a concrete surface.
