Aim to clean your Diog product after each wear or at least before the following day. Simply give them with a light wipe down under water using a brush and cloth to restore the shine.
Use brushes made from natural materials with soft bristles. These will clean more effectively without damage to the fabric.
Don't forget that Diog products should only be cleaned when they are completely wet. Allow them to dry at room temperature; avoid leaving them near a source of heat, as this will harden the fabric. If your product is very wet, stuff it with a small towel to draw out the moisture and allow to dry naturally.
