Read the material and care directions
Match each part to the exact model instructions.
Find the material for each component
A retailer may list TPE for the sleeve and a different material for the outside shell. A trademarked material name can appear without a full material breakdown. Check the instructions for the model rather than applying directions from a different product.
Check cleaning access first
Open ends, removable sleeves and separate caps are different design features. Ask whether the manufacturer allows removal or turning a sleeve inside out. Follow its cleaning and drying directions before closing a housing or storing the item.
