Why This System
Simonton is an all-vinyl manufacturer. Every product family - entry to premium - uses uPVC vinyl frames. The cleaning approach is consistent across the entire range: pH-neutral, solvent-free, no abrasives. The StormBreaker Plus impact-resistant line uses laminated glass in a heavier vinyl frame. Laminated glass has edge seal sensitivity - inspect seals at every clean and do not allow water to pool at the glass base. Simonton products appear heavily in the Southeast US - a climate zone that combines high UV, high humidity, and significant mildew and algae loading on window surfaces. Cleaning intervals in the Southeast need to reflect this.

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 Simonton Windows & Doors 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 Simonton Windows & Doors 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 uPVC 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 Simonton uPVC 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 Simonton 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 Simonton uPVC frames: solvent-free pH-neutral cleaner only -- solvents cause permanent surface damage. Avoid abrasive pads on the profile.
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
- Simonton tilt-wash double-hung windows: clean the lower sash exterior by tilting in from outside. On mid-range tilt hardware, the pivot pin is not captive - if the sash tips too far, the pivot disengages. Keep tilt angle under 90 degrees.
- On Southeast US coastal properties with Simonton windows, a pure water rinse after every conventional cleaning significantly reduces salt deposit re-accumulation rate. Offer this as an add-on service.
- Ply Gem parent company means Great Lakes Window and Atrium products are manufactured to similar specifications as Simonton. If you are confident on Simonton, you are largely confident on those brands too.
What NOT To Do
- Do not use solvent, alkaline, or abrasive cleaning products on vinyl frames
- Do not use bleach concentrations above 3% for mildew treatment
- Do not allow water to pool at the glass base on StormBreaker Plus impact glass
- Do not force tilt-wash mechanisms on double-hung windows
- Do not leave cleaning solution residue on vinyl in direct Southeast sun - it bakes onto the surface

Field Notes
βSimonton is a high-volume presence on Southeast US residential cleaning rounds. Efficient vinyl cleaning technique is the core skill - once established, Simonton rounds are fast and consistent. StormBreaker Plus impact windows in Florida and Gulf Coast areas are premium installations in a high-value market. Homeowners who have invested in impact-rated windows understand their value - position your cleaning service accordingly. In Southeast US summer conditions, cleaning solution dries extremely fast on white vinyl in direct sun. Either clean shaded elevations first or work very early in the day on south and west-facing Simonton windows.β
