How to clean a window with a DI tank and waterfed pole!

Cleaning windows with a DI (deionization) tank and water-fed pole is an efficient, professional method for achieving a streak-free finish without chemicals or ladders . The process relies on the science of pure water to absorb dirt and then evaporate without leaving mineral spots .

Here is a step-by-step guide to using a DI tank and water-fed pole system effectively.

Step 1: Understanding the Science & Setting Up Your Equipment

The Role of the DI Tank: Your DI tank is filled with resin that removes dissolved minerals (like calcium and magnesium) from tap water . This creates “pure water” with a Total Dissolved Solids (TDS) reading of 0 parts per million (ppm) . When this ultra-pure water dries on glass, it leaves no residue behind, resulting in a spot-free shine .

Assembling the System: Connect your water source (tap or a storage tank) to the DI tank, then run a hose from the tank to your water-fed pole . Securely attach the appropriate brush head to the top of the pole .

The Most Important Check: Use a TDS meter to test the water coming out of your pole. It must read 0 ppm before you start cleaning. If the reading is higher, your DI resin is exhausted and needs to be replaced; otherwise, you will get spotted windows .

Step 2: The Cleaning Technique

With your system ready, you can begin cleaning. The key is a systematic approach from the top down.

Start High, Work Down: Begin by cleaning the window frames and sills first. This prevents dirt from these areas from dripping down onto your freshly cleaned glass later . Then, move to the glass itself, starting at the top of the window .

Scrub the Glass: With the water flowing, place the brush against the glass. Use slow, deliberate, overlapping strokes to agitate and loosen all the dirt, grime, and organic material . Allow the continuous flow of pure water to flush the debris away .

Rinse for a Perfect Finish: After scrubbing, you can lift the brush slightly from the surface and use the water flow to rinse the glass thoroughly. Work from the top down in a controlled manner to ensure all loosened dirt is washed away .

Let It Dry Naturally: Once rinsed, simply move on to the next section. The magic of pure water means you do not need to wipe or squeegee the glass. It will air-dry completely spot-free and streak-free .

Step 3: Equipment Maintenance

Proper care of your equipment ensures it performs well and lasts a long time.

Clean Your Brush: After each use, rinse the brush head thoroughly with clean water to remove any trapped dirt or debris. Regular cleaning prevents grit from scratching windows on future jobs . You can also soak it in a mild detergent solution occasionally for a deeper clean .

Check Your Resin: Monitor your TDS meter regularly. When the output water purity rises above 0 ppm, it’s time to replace or regenerate the resin in your DI tank .

Inspect the System: Periodically check your hoses, pole connections, and brush for any signs of wear, cracks, or blockages .
