Maintenance

Cleaning

In areas within the direct influence zones of salt water, industrial chemicals plants, blast furnaces or other aggressive emission sources, the window should be cleaned at least every three months. In a relatively cleaner environment every six months should be sufficient.

In carrying out regular maintenance outside, the internal surfaces are frequently neglected. After a period of time, grime and deposits or from tobacco smoke, coal and oil fires, etc. can discolour the inside window frame and it is recommended that these should be cleaned at least once per year.

Cleaning Procedure

Wash down with clean warm water containing non-alkaline liquid detergent (in concentration which can be handled safely with bare hands) using non-abrasive cloth, sponge or soft bristle brush.This will remove grime, grease, and any excess chalking. All ridges, grooves, joints and drainage channels where salt or other deposits can collect should be well washed out, thus preventing corrosion sites from occurring!

Rinse thoroughly with clean water.

Dry using a soft cloth or leather.

Where a reduction in gloss is observed, chalking is evident or excessive staining has occurred, then an approved renovating cream may be carefully applied with a nonabrasive cloth.

Note: T-Cut or similar automotive paint restorer may be used provided it is not too abrasive! Care must be taken not to abrade sharp corners of sections or aris of beads too heavily where the paint film is normally thinner, and it should be remembered that this operation should not be carried out too frequently. Polish with a soft cloth to restore gloss and colour uniformity.

Hardware

Hinges and locking mechanisms should be lubricated periodically to minimise wear and to ensure smooth operations.
