Joinery
Aluminium joinery is LOW maintenance, not NO maintenance so wash your aluminium windows and doors regularly.
Hardware & Entry Doors
Typically hardware and entry doors come with a powdercoat finish see Care & Maintenance for powdercoating. Remove the protective film covering from new entry doors.
Stainless Steel
Stainless steel is extremely resistant to corrosion but there are some factors that cause it to stain or discolour which can impact on the overall look.
Most discolouration can be removed with a mild cleanser or a specialist stainless steel cleanser and a non-scratch cleaning sponge or cloth. Apply clean water with the cleaning sponge and rub gently. If the mark does not shift, apply the specialist stainless steel cleanser and rub gently. An old toothbrush can be used to get into any difficult areas. The surface should then be thoroughly rinsed with clean water and buffed with a soft cloth.
