SCOPE

Confirm the material before use.

Label-covered areas

  • Window frame surfaces
  • Window and door hardware
  • Sealing strips
  • Other label-covered window surfaces

Patch-test before wider use

  • Unknown materials or coatings
  • Coloured metals, special paint or porous surfaces
  • Oxidised, flaking or structurally damaged windows
  • Any surface encountering the product for the first time

No universal-material claim is made. Stop and ask Dr. Lucheng or the window manufacturer if the label and material guidance conflict.

HOW TO USE

Four steps, with a patch test first.

  1. 01

    Shake well before use.

  2. 02

    Patch-test in an inconspicuous area.

  3. 03

    Apply a small amount to the relevant surface, hardware or seal.

  4. 04

    Wipe evenly with the supplied soft cloth and avoid local build-up.

PRECAUTIONS

Correct use matters more than an “absolutely safe” slogan.

  • Use only for the window-care scenarios stated on the label.
  • Ask before use on unknown materials, special coatings, oxidised or damaged surfaces.
  • Keep cool, dry, away from light and out of children’s reach; avoid ingestion and eye contact.
Check reports and interpretation limits

QUESTIONS

Resolve concerns before purchase.

When should I use the Maintenance Essence?

After cleaning and once the surface is dry. Apply a small, even amount as directed on the label.

Can it be used directly on every window material?

No universal compatibility claim is made. Patch-test unknown materials and special coatings first.

How often should I use it?

Use as needed according to environment, frequency and surface condition; follow the label rather than a universal fixed interval.
