Identify why the glass still shows rainbow effects after cleaning
Service for hotel maintenance teams dealing with iridescence, chemical residue, or deposits affecting guestrooms and public areas.
The team repeatedly cleans the glass, but the rainbow effect reappears depending on the light and viewing angle.
Immediate impact
Maintenance hours can be consumed without correcting the cause, while unsuitable chemicals may intensify the alteration.
What can happen if it is ignored
The visual inconsistency can extend across several rooms or properties and may end up being budgeted as replacement without a proper diagnosis.
Technical cause of the damage
When the rainbow effect remains after cleaning, there may be a chemical deposit or surface alteration. Maintenance teams need to stop repeating products and identify the treatment that restores uniformity.
Common alternatives and hidden costs
Using replacement chemicals without clear criteria consumes labor hours and can intensify the mark; replacing isolated panes creates inconsistency. Restoration identifies the condition and can be scheduled by low-occupancy areas.
Benefits of evaluating restoration
- Differentiation between deposits and surface attack
- Scheduling by low-occupancy areas
- Protection of finishes and furniture
- Recommendations to prevent recurrence
Service process
- We review the cleaning history, identify representative areas, protect finishes, restore during coordinated time windows, and leave observation criteria for the maintenance team’s follow-up.
Scope and limitations
Iridescence does not have a single cause. We identify whether the effect comes from deposits, chemical attack, or a surface alteration and apply the appropriate sequence to restore uniformity and clarity.
We do not work on broken, cracked, fractured or structurally damaged glass. We restore deep damage when the glass is not broken or cracked. Depth changes the work time and sequence, but it does not rule out recovery.

Frequently asked questions
Is the work performed with the glass installed?
Yes. We work with the glass installed as long as it remains intact and safe access is available, avoiding removal and reducing disruption to your space.
Can tempered glass be restored?
We restore tempered glass with superficial or deep damage as long as the glass is not broken, cracked, fractured or structurally compromised.
Does the glass become distorted or weakened?
The specialized process recovers the surface in a controlled manner without distorting the glass or altering its function. Before starting, we confirm the scope using the case’s technical information.
Can deep damage be restored?
Yes. We restore deep damage when the glass remains intact; depth determines the work sequence and time, but by itself does not require replacement.
How is the price determined?
It depends on the type and depth damage, area, number of panes, access, height, location, sector and volume.
When is restoration not possible?
We do not work on broken, cracked, fractured glass or damage that structurally compromises the glass.
What information do you need for an evaluation?
Damage type, location, quantity or area, access conditions and case-specific information. We do not request photographs in the first contact.
Is it worth evaluating before replacement?
Yes. Technical confirmation makes it possible to compare scope, timing, operational risks and direct and indirect costs against replacement.
What happens if a pane cannot withstand the process?
This is very uncommon because Grupo GNOVIA personnel are trained to restore glass using a controlled sequence. In exceptional cases, previously damaged glass may not withstand the intervention. If that occurs, we do not charge for the service performed on that pane; however, we do not assume the replacement cost of glass that was already damaged before work began. This condition is explained clearly before the work starts.
Do you need an on-site visit to confirm the service?
Not in most cases. We can confirm service remotely using the damage description, dimensions, glass type, location, and access conditions. On-site visits are primarily reserved for construction projects or projects involving a large volume of glass.
