Anodized Aluminum, ACM Panels, Window Frames & Steel: Stain Removal, Refinishing & Protection
Architectural Metal Restoration Specialists Nationwide
Architectural metal restoration is the in-place cleaning, refinishing, and protection of a building’s metal surfaces, including anodized aluminum window frames, aluminum composite (ACM) panels such as Alucobond, sandwich panels, metal cladding, and steel, so they regain their original luster without being painted or replaced. Exterior metal faces pollution, hard water, soap residue from window cleaning, leaching from nearby materials, and years of weather. Cleaning metal to the manufacturer’s recommendations only removes surface dirt, and once panels or frames have gone without proper maintenance, only restoration brings back the original finish.
Presto Restoration has restored architectural metal across the United States since 1998. After more than a decade of product research and development, our metal restoration and resurfacing methods remove stains and repair damage without scratching or burning the metal or the surfaces around it. Metal restoration is part of our full commercial facade restoration program, alongside glass restoration and stone and precast restoration.
OUR METAL RESTORATION SERVICES
When windows are cleaned with dish soap, the soapy water gets squeegeed off the glass and onto the metal frames below, where it dries into a sticky film. That film traps dirt and pollution and builds into a dull, stubborn residue that normal cleaning cannot remove. Window frames often go years without the same maintenance as the glass, so the buildup gets worse over time. Presto removes the residue and restores the frame’s original finish.
Mineral-heavy tap water used for window cleaning and nearby sprinkler systems leave hard water stains on metal panels and frames. Over time the minerals bond to the surface and dull the finish. Presto’s products and techniques remove existing stains without scratching the metal, and a protective coating afterward keeps new deposits from forming.
Deteriorating precast, failing caulking, worn coatings, and failed water repellents leach down onto metal surfaces below and leave stubborn stains. Some of the most noticeable stains come from rust running off nearby corroding metal. Presto removes leaching stains from the metal and can address the source above, such as sealing the stone or precast or replacing failed sealants, so the staining does not return.
When metal is not protected during painting or waterproofing work, overspray lands on panels, mullions, and frames. Removing it the wrong way often makes things worse, leaving scratches and damaged finishes. Presto removes paint, sealer, and coating overspray with products that lift the overspray without harming the metal’s factory finish.
Anodized aluminum and other metal finishes can corrode, chalk, and fade after years of exposure to harsh elements. Many owners resort to painting window frames and panels, which needs to be redone again and again. Presto restores anodized coatings and painted metal finishes to their original luster instead, which saves owners the ongoing cost of repainting. This works on metal cladding, ACM and sandwich panels, window frames, storefronts, and steel.
After restoration, we strongly recommend a protective coating to guard against future staining and corrosion. Presto’s high-performance silicone and acrylic coatings shield the metal from water and oxygen, and any stain-forming contaminants settle on the coating instead of the metal, so they wash off during routine cleaning. Presto’s metal protection products include clear, semi-gloss, invisible, and high-performance pigmented coatings. Ask us about the warranty available for your building.
Our Metal Restoration Process
Presto runs every metal restoration project through the same five-phase process, built to identify the finish and the cause of each stain before work begins, protect surrounding glass and stone during the work, and hand over fully documented results at completion.
Building Envelope
Assessment
We inspect the full envelope from the ground, by drone, and at arm’s length via suspended access. Sealants, metals, glass, stone, coatings, and masonry are photographed and logged: every defect mapped before pricing.
Diagnostic Testing
Where leaks or concealed deterioration are suspected, we run controlled water spray tests, infrared thermography scans, and moisture readings to trace intrusion back to its true source instead of patching symptoms.
Scope & Planning
Findings become a line-item scope with quantities, specified products, and a phased schedule. Your project manager handles access logistics, occupant communication, and local permitting.
Restoration Execution
Certified rope-access and swing-stage crews perform the restoration to manufacturer specification, with field supervisors enforcing quality control and documenting progress daily.
Closeout & Warranty
At turnover you receive the complete record: warranty documents, product data sheets, before-and-after imagery, and a maintenance roadmap to protect the investment going forward.
Serving Commercial Buildings Nationwide
Presto Restoration is headquartered in Atlanta and restores commercial, institutional, and multifamily buildings across the United States. Our crews travel to projects nationwide, and in many metro areas local teams support routine maintenance between major restorations.

Why Property Managers Choose Presto for Metal Restoration
Since 1998, Presto Restoration has restored architectural metal on commercial, institutional, and multifamily buildings nationwide. Many companies attack metal stains with abrasives that scratch the finish or harsh acids that burn the metal and the surfaces around it. Our methods remove stains and repair damage without scratches or burns, returning the metal to its original, distortion-free finish. Explore our full range of exterior restoration services.

Metal Restoration FAQs
What is architectural metal restoration?
Architectural metal restoration cleans, refinishes, and protects a building’s exterior metal, such as anodized aluminum window frames, ACM and sandwich panels, cladding, storefronts, and steel, in place. It removes stains, residue, overspray, and oxidation and restores the original finish without painting or replacing the metal.
Can anodized aluminum be restored without painting?
Yes. Presto restores weathered and corroded anodized coatings to their original luster without paint. Painting anodized frames creates a maintenance cycle of repainting every few years, while restoration followed by a protective coating keeps the original finish and saves owners money over time.
What causes stains on metal window frames and panels?
The most common causes are soapy water squeegeed off windows during cleaning, hard water from tap water and sprinklers, leaching from precast, caulking, or coatings above, rust running from nearby corroding metal, and overspray from painting or waterproofing projects. Each one needs a different restoration approach, which is why we identify the cause first.
Can ACM panels such as Alucobond be restored?
Yes. Oxidized, chalky, or faded aluminum composite panels can usually be restored to a like-new finish in place. Restoring panels avoids the cost, disruption, and long lead times of replacing them, and a protective coating afterward slows future fading.
How do you protect restored metal?
We apply a high-performance silicone or acrylic protective coating that shields the metal from water and oxygen and keeps contaminants from bonding to the surface. Warranty terms vary by product and project, so ask us about the warranty available for your building. We also provide cleaning guidelines so maintenance crews do not damage the coating.
Will metal restoration damage nearby glass or stone?
Not with our methods. Presto’s products are designed to restore metal without scratching it or burning the glass and stone around it, and we protect adjacent surfaces during the work. We restore test areas first so you can approve the result before the full project starts.
