Exterior hardware care & maintenance
Keep it bright.
Stainless steel architectural hardware for exterior joinery requires maintenance to ensure a fresh finish and to prevent discolouration or “tea staining.”
To maintain stainless steel hardware
- 01Wash regularly with clean, fresh water, mild detergent, and a cloth or soft brush.
- 02Rinse with clean water and wipe the surface dry with a soft, absorbent cloth, going with the grain on brushed stainless steel.
- 03Generally, wash the stainless steel every time you wash your windows or every 3–5 months.
- 04Avoid using abrasive cleaners or scouring pads as they may cause wear and dull the finish.
If “tea staining” occurs
- 01Use a specialist cleaning product like 3M Stainless Steel Cleaner and a non-scratch cleaning sponge.
- 02Apply clean water with the sponge and rub gently. If the mark doesn’t shift, use a stainless-steel cleaner.
- 03Rinse with clean fresh water and buff with a soft cloth.
- 04Always rub with the grain to maintain the finish.
- 05Never use steel wool as it may scratch the surface and leave fragments that could rust.
