[substeps] Using a thin, natural oil is not recommended because it can break down your chain and cause a rust. (B) [title] Put necklaces away before you shower. [step] Any water can cause your necklace or chain to rust. (C) Take a shower before going out and stick to clean water. If you're wet, your chain could eventually wear out.
