Rust and Adhesive Failure Prevention
Rusty stainless steel and adhesive failure will only happen if the turnstile is used or maintained
inappropriately, or in harsh environments.
Rust Prevention
Do not expose the turnstile to substances that might cause it to rust.
Ions, sulfur oxide, acidic substances that contain HCL and H
2
SO
4
, or substances that produce
acidic substances (such as SO
4
, salt, and HCLO) after dissolving in water will damage the passive
film on the stainless steel.
Substances like soot and dust will disturb the regeneration of the passive film on the stainless
steel.
Metal powder that mostly contains iron will stick to the stainless steel and get rusty.
Adhesive Failure Prevention
After applying protective film to the stainless steel, ensure to protect it from UV rays (direct
sunlight), heat, and pressure to avoid adhesive failure.
After installing a face recognition access controller, apply silicon sealant to the installation hole
to prevent water leakage, and reapply it every two years.

Removing Marks and Rust
Removing Marks from Taking off the Protective Film
Use a sponge or cloth dipped with alcohol, naphtha, banana oil, or a mixed solution of ethyl alcohol
and methylbenzene (or acetone) to clean marks left behind from removing the protective film. These
chemicals are in ascending order of intensity. Use a clean cloth to scrub the stainless steel until the
solution dries up. You can also use any other stainless steel cleaner. No matter which method you use,
clean the surface thoroughly afterwards with clean water.
Removing Palm Marks
A neutral detergent or soap should be enough; otherwise, use an organic solution (such as alcohol,
and naphtha). After scrubbing the surface with a solution, use a clean and dry cloth to wipe off the
solution. Stainless steel cleaner is recommended.
