Why This System
Alside's 100+ supply centre network means contractor relationships are direct and strong in covered markets. This supply chain model means Alside windows are found on contractor-built residential across the Midwest and Southeast in significant volumes. Freeze-thaw cycle performance is a Midwest window requirement that Alside engineering addresses specifically. Frame corners and seal junctions are designed to flex and recover through temperature extremes - but this flexibility has limits if the windows are not kept clean and the drainage channels are not clear. Alside also manufactures vinyl siding. On many Alside-windowed properties, the siding is also Alside. Be aware that cleaning products safe on Alside vinyl windows are also safe on Alside siding - and that siding cleaning chemistry can damage window frames if it migrates. Keep cleaning zones separate.

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 Alside windows to a professional standard β 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 Alside 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 composite 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
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 Alside composite 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 Alside 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 Alside frames, apply the appropriate product for each surface: pH-neutral for aluminium and glass, solvent-free for uPVC, barely damp cloth for timber. Never cross-contaminate products between surfaces.
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
- On Alside double-hung tilt-wash windows, the sash release button is at the top of each sash rail. Press and hold both sides simultaneously before tilting - releasing one side only causes the pivot to bind and the sash to stick mid-tilt.
- Alside Sheffield entry-level windows on new construction builds often have basic screens. Remove and clean screens separately from glass - do not clean glass through the screen. Stack screens in order so they return to the correct opening.
- Midwest post-winter Alside visits are a good time to check the glazing bead condition. Winter temperature extremes stress the glazing bead seal - document any lifting or cracking for the homeowner.
What NOT To Do
- Do not use solvent, alkaline, or abrasive cleaning products on vinyl frames
- Do not allow siding cleaning chemicals to migrate onto window frames
- Do not block or ignore weep holes - critical for drainage in freeze-thaw climates
- Do not force tilt-wash mechanisms

Frequently Asked Questions
Field Notes
βAlside properties in Ohio, Indiana, and Michigan often have Alside siding as well as Alside windows. Position yourself as a whole-home exterior care provider rather than just a window cleaner on these properties - the whole-house relationship is more profitable. Winter-adjacent cleaning visits in the Midwest require extra attention to weep holes and drainage. Post-winter first-cleans should include a thorough track and drainage clearance as a standard line item. Alside Ultramaxx fusion-welded corners are a genuine quality differentiator worth mentioning to replacement window prospects. Corner seam integrity is a long-term performance benefit - the corners stay aligned through temperature cycling better than mechanically jointed alternatives.β
