10 Window Cleaning Tips from a Pro
Save time, money and energy with these tips and pointers from someone who cleans windows for a living. Here's how to get streak-free windows every time.
Two scrubbers are better than one
Use two different scrubbers—one for inside and one for outside—so you don’t carry pollutants and bird excrement inside.
Liquid dish detergent rules
Any kitchen dish liquid cleans dirt and leaves the glass slippery so your squeegee glides with ease. A 100-percent biodegradable soap will protect sensitive plants outside. Inside it will protect toddlers and pets who put their mouth on the windows or sills.
Vinegar works, too
If you prefer to use natural cleaning products, vinegar is a viable choice for cleaning windows. Vinegar (acetic acid) cuts grease and doesn’t streak which makes it ideal for cleaning glass. We recommend a solution of 50 percent white vinegar and 50 percent tap water.

New blade = no streaks
A 12- to 14-inch squeegee is a good size for most situations. Put in a new rubber blade after each cleaning to prevent streaks.
New blade = no scratches
A razor blade removes paint overspray and gunk. Keep the glass wet and use a new blade each time. Microscopic rust particles on the blade can scratch the glass.
Steel wool for tough stains
If you need to remove tree sap, adhesive residue or other tenacious stains from your windows, try #0000 (4 ought) steel wool. Lubricate the glass with a spritz of window cleaner and buff away the stains with a wad of super-fine steel wool.

Scrub away the toughest stains on glass with a small buffing wheel and a mild abrasive (Soft Scrub, Bar Keepers Friend or Bon Ami). When you’re working near the window sash, protect it with masking tape.
