Essential Window Cleaning Tools and Materials


Before diving into the cleaning process, gathering the right tools is crucial for achieving professional results. Here's what you'll need:


  • Microfibre cloths
  • Professional-grade squeegee
  • Bucket
  • Window cleaning solution
  • Soft brush
  • Lint-free cloths
  • Extension pole (for high windows)
  • Safety equipment for elevated cleaning


The Best Way to Clean Windows: Step-by-Step Guide


  1. Choose the Right Time Start your window cleaning on an overcast day. Direct sunlight causes cleaning solutions to dry too quickly, leading to streaks and marks.
  2. Pre-clean Remove loose dirt and debris with a soft brush or vacuum attachment.
  3. Prepare Your Solution Mix your cleaning solution according to manufacturer instructions. For a DIY option, mix warm water with a small amount of mild dish soap.
  4. Apply the Solution Using your microfibre cloth or professional applicator, apply the solution evenly across the glass surface.
  5. Squeegee Technique Work from top to bottom in a reverse S pattern, wiping your squeegee blade clean after each stroke.

  • Work in manageable sections
  • Ensure proper solution dilution
  • Use professional-grade tools


How to Remove Hard Water Stains from Glass


Hard water stains can be particularly challenging to remove.

Here's our professional approach:


  1. Create a Cleaning Paste Mix baking soda with water to create a gentle abrasive paste.
  2. Apply and Wait Gently apply the paste to affected areas and let it sit for 10-15 minutes.
  3. Scrub Carefully Use a soft cloth to work the paste in circular motions.
  4. Rinse Thoroughly Clean the area with pure water to remove all residue.


Common Window Cleaning Mistakes to Avoid


  1. Using Newspaper While traditionally recommended, newspaper can leave ink residue and doesn't perform as well as modern microfibre cloths.
  2. Skipping the Pre-clean Jumping straight to wet cleaning can create muddy streaks.
  3. Using Too Much Product More cleaning solution doesn't mean better results - it often leads to streaking.
