Removing a Small Amount of Rust
Use a stainless steel cleaner.
Removing a Larger Amount of Rust
If metal powder rusts on top of the stainless steel and is not removed in time, the stainless steel will
get rusty itself. Also, if rust caused by salts or other rust-inducing items are not removed in time, it
will get worse. For these two situations, you have to use the specialized stainless steel cleaner. If the
cleaner is not strong enough, use sand papers or a stainless steel brush to remove some of the rust,
and be careful not to damage the stainless steel surface, and then apply the cleaner.

Cautions
Cleaning Requirements
Cut off the power supply before cleaning the turnstile. Make sure that water cannot make
contact with the components inside.
The detergent you use must not contain abrasive matter, otherwise the turnstile surface will be
damaged.
Clean along the lines on the surface.
Use cloth to dry the surface after using detergent and clean water.
Detergent Requirements
Choose a stainless steel cleaner according to the actual situation. The ones with over 30% active
ingredients are recommended.
Do not use acidic substances, especially sulfuric acid, sulfurous acid, and those that contain
chlorine.
If there is adhesive failure, use organic solutions that have no oxidative capacity. Alcohol,
dimethylbenzene, and acetone are normally used.
For stainless steel with a processed surface (mirror finish or titanium coating), make sure that
you use a neutral detergent containing no abrasive matter.
