This Secret Pressure Washing Chemical Will Make You A Fortune


Welcome back to the channel! Today, we're diving into a big question: Can you remove oxidation on Hardy plank? The answer is a resounding yes, and we're here to show you how with Ox-Knox.

The Problem: Hail Damage and Oxidation

We encountered a homeowner whose house got pelted with hail, causing significant oxidation on one side of the Hardy plank siding. The challenge was to remove this oxidation efficiently without the need for labor-intensive brushing.

The Solution: Ox-Knox to the Rescue

We're using Ox-Knox, our go-to chemical for brushless oxidation removal. With a 4:1 ratio mix, applied using a pump-up sprayer, we're able to restore the siding to its former glory. For those of you running a pressure washing business, this method will save you time and effort while delivering outstanding results.

Step-by-Step Process

  1. Pre-Wet the Wall: Start by pre-wetting the wall to prepare it for the application of Ox-Knox.
  2. Apply Ox-Knox: Use a pump-up sprayer to apply the Ox-Knox solution. You could also use an X-Jet for a similar application strength.
  3. Dwell Time: Allow the solution to sit for a bit. Play around with ratios and dwell times to achieve the best results.
  4. Rinse Off: After the solution has done its job, rinse off with a garden hose or a contractor-grade sprayer.

Real-Life Results

We conducted a demo at a homeowner's property in Auburn, Alabama, a town I absolutely love. The homeowner was thrilled with the results. Here's what she had to say:

"I love it! It looks great and took less than 10 minutes. We were thinking about painting the house, but now we’re going to clean it with Ox-Knox instead."

  • Cost-Effective: Save thousands of dollars on repainting by restoring the original look of your siding.
