1. I’VE TRIED OTHER SYSTEMS WITH LIMITED SUCCESS. WHAT KIND OF GUARANTEE DO I HAVE THAT GLASSRENU ACTUALLY WORKS?
GlassRenu is unlike any other commercial system on the market. It repairs scratches, acid damage, fabrication debris, and hard water stains faster, cleaner, and at a lower cost per repair without distortion.
We offer the industry’s only Product Performance Guarantee: if your GlassRenu System doesn’t perform as promised, we’ll buy it back within the first 30 days of ownership.
2. HOW DEEP OF A SCRATCH CAN GLASSRENU REMOVE?
GlassRenu has never received a report of a deep scratch it couldn’t remove. It regularly removes scratches between .004″–.010″ with no distortion and is working with ANSI to demonstrate no-distortion results at .010″, .015″, and .020″.
GlassRenu can also handle deep damage like chipped glass fragments and glass dust, though such repairs may take more time, often billed at 50% of glass replacement costs.
3. DOES GLASSRENU WORK ON TEMPERED GLASS?
Yes, GlassRenu works on tempered glass, which is heat-treated for strength and safety. It produces the same clarity and no visible distortion as with traditional glass.
4. DOES GLASSRENU WORK ON MIRRORS?
Yes, as mirrors are essentially flat glass with a reflective backing, GlassRenu works effectively on them.
5. HOW DOES GLASSRENU WORK ON SCRATCHES FROM CONSTRUCTION, LIKE STUCCO DAMAGE?
Stucco damage is common. Users report saving homebuilders significant costs by repairing damaged glass onsite, without removing it, and achieving no-distortion results. For example, one user repairs 8–10 windows per house daily, charging $75–$95 per window.
6. CAN GLASSRENU HANDLE LARGE JOBS?
Yes. For instance, a user repaired approximately 2,000 sq. ft. of concrete-damaged glass in four weeks with four men and two systems, saving over 44% compared to replacement costs.
7. I AM GETTING LIGHT (DEEP) SWIRL MARKS WHEN GRINDING, WHAT AM I DOING WRONG?
There are two possibilities:
The RenuDisk is not completely flat against the glass, causing overlapping concentric arcs.
Too much force is applied, creating overlapping circular swirls. Reduce pressure to stop the swirls.
8. OK, SO NOW I KNOW WHAT I DID TO PUT THE SWIRLS IN, HOW DO I GET THEM OUT?
Treat the swirl as any other scratch. Grind the glass just until the scratch is gone—no more, no less.
9. I JUST FINISHED REPAIRING SOME GLASS, BUT WHEN I LOOK AT AN ANGLE, I SEE A FOGGY SHADOW. WHAT AM I DOING WRONG?
Foggy shadows are caused by:
Insufficient time with the Pre-Polish disk, leaving grinding traces.
Inadequate polishing.
A good practice is to grid off the repair area and work section by section until the glass is clear from all angles.
10. HOW DOES THE FEATHERING TECHNIQUE WORK IN THE GLASSRENU PROCESS?
Start by focusing on the damaged area. Gradually expand the work area by an inch every few passes until the original damage is completely gone. This ensures a distortion-free result.
11. HOW LONG SHOULD MY RENUDISKS LAST?
The average grinding disk can be reused for up to 15 sq. ft. of repairs. A new pre-polish (grey) disk should be used for each job.
12. HOW OFTEN SHOULD I CLEAN THE SURFACE OF THE RENUDISK?
Clean the disk frequently using the back of a wire brush during the grinding phase. Dust build-up reduces the disk’s effectiveness and slows down the repair process.
13. HOW LONG SHOULD I PRE-POLISH BEFORE SWITCHING TO A POLISH PAD?
The goal during pre-polish is to completely remove grinding marks. Polishing should continue until the glass is clear from all angles. With practice, you’ll determine how long it takes for each repair.
14. WHAT TYPES OF GLASS CAN GLASSRENU REPAIR?
GlassRenu works on virtually all types of glass, including tempered, laminated, annealed, low-E coated, and mirrors. Whether it’s residential windows, storefronts, automotive glass, or specialty glass, our system delivers exceptional results without distortion.
15. DOES GLASSRENU REMOVE HARD WATER STAINS?
Yes, GlassRenu is highly effective at removing hard water stains. The process not only clears the stains but also restores the glass surface, leaving it smooth and free of etching or damage caused by prolonged mineral exposure.
16. CAN GLASSRENU BE USED FOR AUTOMOTIVE GLASS?
GlassRenu can be used for specialty or vintage automotive glass restoration where replacement is costly or unavailable. However, it is not intended for severely chipped or cracked windshields.
17. IS GLASSRENU SAFE TO USE?
Yes, GlassRenu is designed with safety in mind. Always follow the provided training guidelines and wear appropriate personal protective equipment (PPE) like safety glasses and dust masks when using the system. Proper technique minimizes risks like overheating the glass or creating unnecessary stress.
18. HOW LONG DOES IT TAKE TO COMPLETE A GLASS REPAIR?
Repair time depends on the extent of the damage and the type of glass. Most minor scratches and hard water stains can be repaired in 20–30 minutes, while deep scratches or large areas of damage may take longer.
19. CAN GLASSRENU BE USED OUTDOORS?
Yes, GlassRenu can be used outdoors for storefronts, home windows, and other exterior applications. It’s recommended to avoid working in extreme weather conditions, as temperature fluctuations may impact the repair process.
20. HOW MUCH DOES IT COST TO REPAIR GLASS USING GLASSRENU?
The cost of repair depends on the damage, but most users bill 50%–75% of the replacement cost. This provides substantial savings for customers and ensures profitability for service providers.
21. WHAT IS THE RETURN ON INVESTMENT (ROI) FOR GLASSRENU SYSTEMS?
GlassRenu systems offer a high ROI. Many users report recovering their investment within the first few large jobs, thanks to the system’s efficiency and cost-effectiveness compared to glass replacement.
22. CAN I GET TRAINING ON HOW TO USE GLASSRENU?
Yes, GlassRenu offers comprehensive training materials, including videos, guides, and live demonstrations. We also provide ongoing support to ensure users are confident and successful with the system.
23. DOES GLASSRENU REMOVE FABRICATION DEBRIS?
Yes, GlassRenu effectively removes fabrication debris from newly manufactured or installed glass. The system ensures a clear, defect-free finish without the need for replacement.
24. CAN GLASSRENU HANDLE SCRATCHES CAUSED BY METAL OBJECTS?
Yes, GlassRenu is highly effective at removing scratches caused by metal tools, keys, or other objects. The system grinds away the damaged layer of glass and restores the surface to its original clarity.
25. WHAT IS THE DIFFERENCE BETWEEN GRINDING AND POLISHING?
Grinding: Removes the damaged layer of glass using abrasive disks.
Polishing: Restores the glass surface to its original clarity after grinding.
Both steps are essential for a distortion-free finish.
26. DOES THE SYSTEM WORK ON COATED GLASS (LIKE LOW-E GLASS)?
GlassRenu can work on low-E coated glass, but care must be taken to avoid removing the coating. It’s essential to assess whether the damage is limited to the surface or penetrates the coating layer.
27. CAN GLASSRENU RESTORE ETCHED OR SANDBLASTED GLASS?
Yes, GlassRenu can restore etched glass caused by graffiti or sandblasting. The process removes the damaged surface and restores the clarity of the glass.
28. WHAT IS THE ENVIRONMENTAL IMPACT OF USING GLASSRENU?
GlassRenu is an eco-friendly alternative to glass replacement. By repairing rather than replacing glass, users reduce waste and the carbon footprint associated with manufacturing and transporting new glass.
29. DO I NEED SPECIAL TOOLS OR EQUIPMENT TO USE GLASSRENU?
The GlassRenu system comes with all the tools you need to get started, including RenuDisks, polish pads, and training materials. Additional accessories can be purchased separately if required.
30. CAN GLASSRENU REPAIR MULTIPLE TYPES OF DAMAGE ON THE SAME GLASS?
Yes, GlassRenu can repair multiple types of damage—such as scratches, hard water stains, and etching—on the same pane of glass. Simply follow the appropriate process for each type of damage.
31. HOW DOES GLASSRENU COMPARE TO OTHER GLASS RESTORATION SYSTEMS?
GlassRenu is faster, more efficient, and delivers distortion-free results that most other systems cannot match. It is also more cost-effective, making it the preferred choice for professionals.
32. DOES GLASSRENU OFFER WARRANTY OR SUPPORT?
Yes, GlassRenu offers a warranty on its systems and provides ongoing support for all users. Our customer service team is available to answer questions and provide troubleshooting assistance.
