WHY EVALUATE RESTORATION

For suitable conditions: lower total cost, faster resolution, controlled quality

These are decision criteria, not universal promises. Confirm the glass, condition, access and acceptance requirements through a representative trial.

Lower total cost

Offer a priced repair option where cleaning alone cannot resolve the concern.

Faster resolution

Identify restoration opportunities during established customer service relationships.

Controlled quality

Identify the condition, qualify the method and inspect the finished glass.

THE DECISION

A practical restoration decision

Some visible marks remain after appropriate cleaning. Recognize when a concern needs restoration assessment rather than another cleaning attempt.

FROM ASSESSMENT TO ACCEPTANCE

Know when the cleaning visit becomes a restoration conversation

Do not keep escalating cleaning chemistry or abrasion when the remaining condition needs identification.

  1. Complete the appropriate cleaning test and document what remains.
  2. Identify deposit, stain, etch, scratch or another damage family.
  3. Explain the separate restoration scope, limits and representative test.
  4. Inspect the test with the customer before pricing or expanding the work.

TECHNICAL DETAIL

Use the decision model in this work environment

Still removable

If the appropriate cleaning test changes or removes the material, remain in the cleaning scope and document the result.

Persistent appearance

If the concern remains, classify deposit, stain, etch, scratch or transferred material before changing tools or chemistry.

Separate restoration scope

Quote restoration as a distinct service with a representative test, stated limits and customer review - not as more aggressive cleaning.

COMMON QUESTIONS

Before a pilot or project begins

When should cleaning become an assessment conversation?

When the appearance concern persists after the appropriate cleaning approach, document it and identify the condition before proposing a more aggressive process.

Do I need a trained in-house operator?

You can develop in-house capability through a suitable system and training plan, or connect the customer with an independent provider. Confirm the provider’s training and project suitability.
