Anyone who has cleaned a window in Tampa Bay knows the frustration. You wipe it clean, step back, and the whole pane is covered in streaks. Humidity slows drying, the sun bakes the cleaner into the glass, and pollen and salt air coat the surface again within days.
A few changes to timing and tools solve most of it. This guide covers the best time of day, what to use, how to clean the parts around the glass, and what to do when the haze is on the inside of a double-pane window.
What this post covers:
- Pick the right time and weather
- What to use, and what to skip
- The wipe and dry method
- Sills, tracks, and screens
- Condensation and haze between panes
- How often to clean in Florida
Pick the Right Time and Weather
Timing is half the work. Cleaner dries too fast in full sun and too slowly in thick humidity, and both cause streaks.
- Choose a cloudy morning or a shaded window. Direct sun makes cleaner dry in spots and leave marks.
- Avoid the hour after a rain shower, when the air is saturated and glass stays damp.
- Pick a drier day if you can. Cool, dry mornings in winter and early spring are the easiest.
- Do the inside and the outside on the same day, so you can tell which side a streak is on.
If you have a lanai or screened porch, the windows facing it will collect pollen and film faster. Check them first.
What to Use, and What to Skip
The best window cleaner is the simplest one. Fancy products often leave a film that attracts more dirt.
- A spray bottle with warm water and a few drops of dish soap, or a half and half mix of water and white vinegar
- Two clean microfiber cloths, one for washing and one for drying and buffing
- A rubber squeegee for large panes
- A soft brush or old toothbrush for corners
- Newspaper or lint-free paper towels for last-minute spots
Skip paper towels that shed lint, and skip any cleaner that is thick or sudsy. Too much soap is the main cause of streaks. Never use abrasive pads on glass.
The Wipe and Dry Method
Work from the top of each window down, and wipe the dirty parts first so you do not smear them across clean glass.
- Brush or vacuum loose dust and cobwebs off the frame and glass.
- Spray the glass lightly. A few sprays are better than a soaking.
- Wipe the glass with the damp microfiber in an S pattern, from top to bottom.
- Wipe the edges with the cloth so the cleaner does not run down and mark the pane.
- Immediately dry and buff with a second dry cloth, using straight strokes.
- Check the glass from an angle. Streaks show best in side light.
If you use a squeegee, wipe the blade with a cloth after every pass. Start at the top corner and pull straight down in one stroke, overlapping by an inch.

Sills, Tracks, and Screens
Clean glass looks wrong in a dirty frame. The sills and tracks hold the dust and moisture that make glass look bad again within days.
- Tracks: vacuum with a crevice tool, then scrub with an old toothbrush and soapy water. Dry well to prevent mildew, which grows fast in damp Florida tracks.
- Sills: wipe with a damp cloth. Check for black spots that could be mildew, and wash them with detergent and water.
- Screens: take them out and rinse with a hose, or wipe with a damp cloth. Let them dry fully before putting them back.
- Weep holes: the small drainage holes along the bottom of the frame often clog. Clear them with a pipe cleaner so water can drain.
Interior windows are often the first thing homeowners skip. If you want them done, remember that this is a different task from exterior glass, which is usually a separate job and may involve ladders.
Condensation and Haze Between Panes
If a haze or fog shows up between the two panes of a double-pane window, you cannot wipe it away. It means the seal has failed and moist air has gotten inside. Cleaning will not fix it.
- Condensation on the inside of the glass can mean the indoor humidity is too high. Run the AC or a dehumidifier, and use the bathroom fan after showers.
- Condensation on the outside, on a cool morning in a warm home, is normal and clears as the day warms.
- Fog between panes needs a glazing company or a replacement glass unit.
- Wet window sills and black spots at the bottom of the frame can mean a leak, not just condensation. Look for failed caulk around the outside of the frame.
EPA's guidance on mold and moisture says to keep indoor humidity low, ideally between 30 and 50 percent, and to act quickly when condensation collects on windows. You can read it on EPA's page on mold, moisture, and your home.
How Often to Clean in Florida
Every home is different, but a rough schedule works well here.
- Inside glass: once a month, or more often if you have pets or children who touch the glass.
- Outside glass: two to four times a year, and after heavy pollen season in spring.
- Tracks and sills: every time you clean the glass, since that takes only a few minutes.
- After a storm: check for salt, sand, or debris, and wipe the sills.
A deep clean covers interior glass, sills, and tracks along with the rest of the house, so it can reset everything at once. If your lanai windows and screens are the worst offenders, see our lanai and patio cleaning tips. Our spring cleaning guide includes windows in the Tampa Bay timeline.
