Step-by-Step Guide: Cleaning Windows with Ha-Ra
Step 1: Prepare Your Cleaning Solution
Ha-Ra’s pH-neutral Protective Formula is ultra-concentrated, so a little goes a long way. Add just 2-3 drops of detergent on your window cleaning fibre.
Why it matters: The formula helps break down stubborn dirt and grease while leaving a protective layer that repels future grime and rain spots.
Step 2: Dampen the Fibre Side of the Window Cleaner
Run the fibre pad (blue side) under clean water until it is damp but not dripping.
Pro tip: You don’t need to soak the fibre. A well-dampened cloth is more effective and won’t leave streaks.
Step 3: Clean the Window Using Horizontal or Vertical Strokes
Using moderate pressure, glide the damp fibre side of the window cleaner over the glass surface. Use consistent strokes either from top to bottom or left to right.
Focus on edges and corners where grime builds up. The high-quality microfibres will lift and trap dust, grease, fingerprints, and other residues.
Step 4: Flip and Dry with the Squeegee Blade
Wipe the glass with the rubber blade using the same stroke direction as the fibre side, overlapping slightly with each pass.
Wipe the blade with a dry cloth between strokes to prevent streaks.
Pro tip: Angle the blade slightly so water runs down and away from the clean area.
Step 5: Touch-Up with a Polishing Cloth (if needed)
If there are any small drips or corners that need extra attention, use a Ha-Ra Polishing Cloth to gently buff the area. This ensures a crystal-clear, streak-free finish.
Bonus: Tips for Exterior Windows
Cleaning exterior windows? Here’s how to take it up a notch:
-
Attach the Extension Handle: Reach second-storey or high windows with ease.
-
Remove Loose Debris First: Quickly brush or hose down dust, cobwebs, or leaves with the Outdoor Cleaning Glove.
-
Work on a Cloudy Day: Direct sunlight can cause water to dry too fast and leave spots.
