Step 1 of 2: Manufacturer Recommendations

Official Care Guidance

Glass

• ✓Pre-rinse glass with pure water to remove salt and organic residue before applying cleaning solution - skipping this step grinds deposits into the glass surface.
• ✓Use a pH-neutral glass cleaning solution. Avoid acidic cleaners on glass near aluminium frames - acid runoff attacks the powder coat at the frame-glass junction.
• ✓Squeegee technique: single straight pulls from top to bottom. Overlap each stroke by 2cm. Wipe the rubber after each pull.
• ✓Check glass unit seals at every clean. Tropical UV degrades silicone seals faster than temperate UV. A failed seal shows as condensation between the panes or a dark silicone bead.

Aluminium Frames

• ✓Wipe frames with a soft cloth dampened with pH-neutral solution. Work top to bottom so dirty water runs onto uncleaned surfaces.
• ✓Do not use abrasive pads on powder-coated frames - even white chalked surfaces. Abrasion removes the remaining UV-resistant layer.
• ✓Rinse frames thoroughly after cleaning. Cleaning solution residue left on powder coat in tropical heat accelerates UV degradation.
• ✓If chalking is present, consult the property manager about frame recoating rather than attempting to clean it away.

Tracks and Rollers

• ✓Vacuum or brush the track channels before introducing water - wet grit in tracks forms an abrasive slurry that damages roller surfaces.
• ✓Flush track channels with clean water and a narrow brush. Pay particular attention to corner accumulation points.
• ✓Clear weep holes with a thin wire or toothpick. Do not use metal implements in powder-coated track surfaces.
• ✓After cleaning, apply a small amount of silicone lubricant to the track surface - not to the rollers themselves. This reduces rolling resistance and slows grit adhesion.

Pro Tools

My daily tool list. This is what I carry to every job.

Follow these steps in order. Each one builds on the last. This is the same sequence I use on every Perfect Window Systems installation.

1. 1

   Preparation -- before any water touches the glass

   Fill the bucket with at least 10 litres of water. Add soap for cleaning power -- enough to cut through environmental deposits, not so much you are fighting foam.

   Before touching the glass, brush down the surface to remove loose dust, spiderwebs, and debris. Any grit left on the glass during the wash phase risks scratching during agitation.

   Check the aluminium frame condition before you start. Confirm which cleaning product is safe for that surface before opening any bottle.

   Cover anything below the windows that cannot be moved.

2. 2

   Agitation -- apply and work the solution

   Dip the microfiber T-bar completely into the soap water, both sides. Remove excess water with your hand so it does not drip. Apply the solution across the entire glass surface with overlapping passes.

   The goal is to fully dissolve and release every deposit from the glass surface. Anything not released during agitation gets transported across the glass by the squeegee as a smear.

   For stubborn spots -- insect marks, salt residue, environmental deposits -- re-apply soap water and allow it to soak for a full minute before agitating again. Use more soap water, not more pressure.

   For panels above arm reach: attach the T-bar to an extension pole. Work in sections -- top first, then middle, then bottom -- keeping each section wet until you squeegee it.

   Rinse the T-bar cover regularly during the job. A dirty applicator causes microscopic scratches that accumulate over time.

3. 3

   Detail the frame edge before squeegeeing

   Use your 100% cotton towelling rag, finger pressed into the fabric, to work into every junction and remove pooled soap water before the squeegee pass.

   This prevents drips running down onto already-cleaned areas during squeegeeing and keeps soap water out of drainage channels.

   On Perfect Window Systems aluminium frames, pay particular attention to the bottom edge where glass meets the frame sill -- water pooled here runs into drainage openings and leaves residue over time.

4. 4

   The squeegee

   Tilt the squeegee at a slight angle so soap water spills from one side of the channel only -- not both. If the rubber is jumping or squeaking, either the rubber is not lubricated enough or the glass surface has warmed.

   Cutting in: start with the rubber blade making first contact on a dry edge of the glass.

   Side to side: horizontal passes across the panel. Works well on wide sections. Top to bottom: vertical passes down the panel. Works well on tall narrow sections.

   The J tune: one smooth unbroken motion top to bottom, wrist rotating at each end to reverse without lifting the rubber. The most efficient method on larger panels -- but it requires training before applying it to premium glass.

   Wipe the rubber dry after every pass. Overlap each stroke by 2-3 cm.

5. 5

   Final edge detailing

   After squeegeeing, there is always a residual line of water along the bottom edge and at the panel sides. Take a dry cotton rag, fold to a clean corner, and detail these edges in one smooth pass.

   On Perfect Window Systems frames, the bottom edge where glass meets the sill requires the most careful attention. Water left here runs into drainage and leaves residue that affects the next clean.

   Rotate the rag to a clean section after every pass. If the rag picks up grit at any point, replace it immediately.

6. 6

   Frame wipe and hardware check

   On Perfect Window Systems powder-coated aluminium frames: use pH-neutral cleaner only, never abrasive pads or steel wool. Dry immediately after wiping.

   Check that all drainage openings are clear and unobstructed. Water must be able to flow freely -- a blocked channel leads to accumulation that affects seal performance over time.

   Operate every opening window through its full range. Stiff handles or resistance at locking points indicate hardware that needs lubrication. Flag it to the owner rather than forcing it.

Pro Tips

• ★ Schedule Singapore cleaning visits for the cooler morning hours - cleaning solution dries too fast on sun-heated glass in afternoon conditions and leaves residue marks
• ★ Carry a separate cloth for aluminium frames and a separate cloth for glass - cross-contamination of frame residue onto glass is a common cause of streaking in tropical conditions
• ★ On awning windows, open the sash fully before cleaning the outer face - the top hinge area is inaccessible on a partially open awning

What NOT To Do

Bundle Kits and Tool Recommendations

Cleaning Frequency

Coastal and high-rise positions: Every 4 weeks (Salt air and wind-driven organic matter accumulate fast at height and near coast). Inland residential: Every 6 to 8 weeks (Lower salt exposure but still significant UV and organic loading). Post-monsoon event inspection: Within 1 week of major rain (Check drainage channels and weep holes after heavy monsoon rainfall)

Frequently Asked Questions

Field Notes

“Singapore windows need cleaning every 4 to 6 weeks in exposed coastal or high-rise positions. Inland low-rise positions can extend to 8 weeks maximum before organic staining sets into the frame junctions. After a major monsoon rain event, inspect all weep holes and drainage channels on the following clean. Monsoon rainfall carries organic debris that blocks drainage faster than normal rainfall. Powder coat chalking on older aluminium systems is endemic in Singapore - particularly on west and south-facing elevations. Document chalking at the first visit and flag it to the property manager. Cleaning crews should not be responsible for pre-existing coating breakdown.”
