Cleaning Guide

Acrylic Mirror Cleaning Guide:

General Cleaning:
DuraVisionTM recommend cleanning their acrylic mirror faces with soap and water and then with a clean, soft, lint free, damp cloth. Use a non-abrasive polish, such as Johnson’s Pledge or Mr Sheen for a clear bright reflection.

Saturate a clean soft cloth with polish, then spray the mirror face with polish. Wipe the wetted cloth over the mirror surface. With a another clean dry cloth buff the mirror face until it is clear of polish.

DO NOT USE:

  • abrasives
  • acids
  • solvents such as petrol and laquer thinners

Graffiti Removal:
Any graffiti should be removed from the mirror face as soon as possible and preferably within 24 hours. To remove graffiti, use a non-abrasive substance such as De-Solv-it Stain Remover. Not all graffiti cleaning agents are suitable. Failure to use an approved cleaning agent may damage the mirror surface.

Scratches:
To remove scratches or repair blemishes on acrylic mirror faces only, use the following products:

  • For cleaning use NOVUS plastic polish #1
  • For fine scratches use NOVUS plastic polish #2
  • For badly scratched surfaces use NOVIS plastic polish #3 followed by #2 and #1.
