Why This System
Alumasa's Santa Catarina base means their products are factory-tested in subtropical conditions - heavier winter rainfall and cooler temperatures than the tropical north. This influences how drainage and sealing are designed into the frame. Southern Brazil's winter rainfall season (June to August) puts sustained water pressure on drainage paths in a way that tropical storm events do not. Prolonged moderate rain is different from intense short bursts - weep holes and drainage channels need to handle sustained flow, not just peak intensity. Alumasa serves the volume residential market - products appear in standard house construction across the south. The cleaning approach is straightforward aluminium care, but climate-adapted for the subtropical south rather than the tropical north.

Step 2 of 2: The Orloffs Protocol
The Orloffs Protocol
Since 1999 I've cleaned hundreds, if not thousands, of different window brands and systems. The physics of clean glass don't change from one brand to the next. Follow the steps below and you'll clean your Alumasa windows to a professional standard โ guaranteed.
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 Alumasa installation.
- 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.

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.

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 Alumasa 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
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
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 Alumasa 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
Frame wipe and hardware check
On Alumasa 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
- In Santa Catarina winter, complete outdoor cleaning before noon - afternoon weather deteriorates rapidly from June to August
- After heavy winter rain, check weep holes as a priority before starting glass cleaning - blocked drainage must be cleared first
What NOT To Do
- Do not use abrasive pads on powder-coated frames
- Do not use acidic cleaners on or near aluminium frames
- Do not skip drainage inspection in winter months - sustained rainfall makes blocked weep holes a water ingress risk within days
- Do not use bleach on rubber seals

Frequently Asked Questions
Field Notes
โSanta Catarina winter (June to August) is the critical maintenance season for Alumasa windows - sustained rainfall creates drainage pressure that is absent for the rest of the year. North-facing elevations in Santa Catarina receive less sun in winter and sustain more biological growth (algae, lichen) than other aspects. Prioritise these elevations for mould and growth inspection. Southern Brazilian residential construction often uses Alumasa frames alongside other regional brands - a single project may have mixed frame types. Identify each before cleaning.โ
