Should the need arise, my go to steps for cleaning chainmaille are as follows:
1 - put the item in a bowl with room temperature water and mild liquid dish soap
2 - stir around for a moment to agitate the soap, then let soak for a couple minutes
3 - if it's extra dirty, gently polish with a soft cloth after soaking
4 - rinse thoroughly and pat dry with a cotton cloth
5 - make sure items is completely dry before storing

Storage Recommendations
When not in use, storing your chainmaille in individual fabric bags inside a jewelry box is ideal. Silica gel packets are useful for enclosed spaces. Jewelry racks are also a great option for easy storage.

No matter which option you choose, it's best to store your items away from sharp objects to minimize sratching.

Important Note For Aluminum Chainmaille
When it comes to cleaning aluminum, in particular anodized aluminum, it's best to avoid anything acidic so the color doesn't fade. Using mild liquid dish soap that's citrus free is recommended.
