Power Washer Marks Removal Process

To ensure effective and maximum cleaning efficiency, I suggest you follow every step with due diligence and maximal proficiency.

Step 1: Water the Effected Vinyl Siding Area

In the very first stage, you have to water the affected area of the siding with a water jet machine. But keep the water pressure level below moderate otherwise, you may cause more damage to the siding because of high water pressure.

This step is basically a pre-cleaning stage for starting the main removal process. After watering, let the siding dry for 15 to 20 minutes.

Step 2: Spray Vinegar

After cleaning the affected spots through watering, here comes one of the most important parts of the whole removal process. In this stage, you have to spray the distilled white vinegar with a water jet in the washer-marks-affected areas.

Distilled white vinegar: Solution of 70% water and 30% white vinegar.

Actually, the washer marks are one of the accumulated forms of water. As water is mineral, the washer spots are chemically alkaline in nature. So, the best method to remove these spots is to use any elements which are chemically acidic (opposite to alkaline nature).

Vinegar is pretty much powerful enough to break down the washer water spots from the vinyl siding. On top of that, it is quite mild enough that it won’t damage the siding.

Now, let the vinegar dry on those spots for 30 to 40 minutes. If the washer marks are too hard are in form and are not breaking down easily, then spray vinegar again after 30 to 40 minutes.

You may continue this process consecutively a maximum of 2/3 times. Spraying vinegar more than 2 to 3 times will increase the acidity, ultimately resulting in damage to damage.

Step 3: Spray Bleaching Power or Detergent

Once you break down the accumulated water form (washer marks) in the siding by spraying vinegar, it is time to facilitate the breaking process. So, this step directs you to spray a solution of bleaching powder or detergent on the affected areas of the siding.

First, make the bleaching power or detergent solution and pour it into the water jet container. Now, spray the solution on the affected areas. Remember to set the speed of the water jet below-moderate level. Make sure to spray them when the vinegar is completely or substantially dried.

When you spray detergent solution at the place where you have already sprayed vinegar earlier, it basically starts cleaning the residues of the chemical breakdown.

Step 4: Rub the Washer Marks Affected Spots with Sponge

In this stage, mostly body labor is required. After you have sprayed the detergent solution, start rubbing those areas with sponges or non-abrasive scrubs. Don’t use any hard scrubs or sponges; because they will cause permanent damage to the siding.

Don’t use high pressure on the scrubbing or rubbing. Take time and scrub the affected areas slowly. The more time you provide on scrubbing, the higher the possibility of removing the washer marks without causing damage.

Use a ladder if the areas required to rub are not accessible from the ground.

Step 5: Washing the Siding

OK, you have come to the last stage. Once you are completed rubbing all the affected siding areas, wash the siding using the jet water machine. Slowly spray the water and clean the vinegar, detergent, and scrub residues from the siding.

Follow this step twice to ensure that any component is not left behind in the siding to wash.

Please Note This Down: Power or pressure washing at the wrong speed often causes permanent damage to the siding, like dents, fractures, and rifts. Besides, it often leaves many hard and non-removable washer marks on the siding. In such cases, this removal process will not come to your help.

This removal process is generally applicable when washer marks are mild in nature and not that hard. Moreover, this process will guarantee substantial removal of washer marks, not 100%.

Frequently Asked Questions (FAQs)

Vinyl siding is a special formation of plastic which is polyvinyl chloride (PVC). Using raw vinegar in your siding will definitely cause substantial damage because the raw vinegar (acetic acid) is highly acidic. It will break down the chemical formation of polyvinyl chloride plastic.

In contrast to what you may have been led to believe in the past, pressure washers are not only simple to use but also entirely safe when it comes to washing your siding.
