Wash a G-SHOCK resin strap with water, then wipe it dry with a soft cloth. Rinse it promptly after contact with salt water, mud, chlorine, or other residue, and dry it before storing the watch. Check the manual for your exact model, particularly if the strap has metal parts or the watch is old or damaged.
Clean a resin strap with water and a soft cloth
For routine sweat or dirt, wipe the strap with a soft cloth. When it needs a wash, use water and wipe it dry with a soft cloth. Casio gives this care instruction for resin bands and does not specify a dedicated resin cleaner.

If a stain-like mark appears, Casio advises wiping it with a cloth. Avoid hard rubbing: it can damage printed sections, and light-colored or transparent resin may be especially prone to visible discoloration.
Rinse residue off promptly
After seawater or mud, rinse the strap with clean fresh water. G-SHOCK’s US water-resistance guidance also calls for rinsing after exposure to salt water, chlorine, dirt, or other residue, followed by drying with a soft cloth. Remove sweat and moisture before putting the watch away.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.

- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
Keeping the strap clean and dry matters because Casio warns that sweat or water left on resin parts, as well as storage in a humid place, can contribute to premature wear, cuts, and breaks.
Use extra care with metal parts and water resistance
If the band includes metal parts
Follow the manual for your specific watch. One Casio manual gives mild neutral detergent or soapy water guidance for metal parts and cautions users to protect the case from detergent. That is not a general instruction to apply soap to the resin strap.

If you are unsure whether the watch can be rinsed
Do not assume every G-SHOCK has the same water resistance, or that a resin strap makes the watch safe to immerse. The printed rating does not establish the current condition of an older or damaged watch. Check the model manual and the watch’s condition; if water resistance is uncertain, clean the strap’s surface with a damp cloth and ask Casio service for guidance.

Avoid chemicals and aggressive scrubbing
Casio warns that solvents and other chemical products can discolor or damage resin. Keep the strap away from thinners, gasoline, solvents, oils, cleaners containing them, adhesives, paints, and chemicals. Sunscreen and cosmetics may also discolor or damage resin.
Long exposure to sweat, dirt, moisture, humidity, and direct sunlight can contribute to deterioration or discoloration. These effects may be more visible on light-colored or transparent resin and printed areas. Casio’s guidance does not establish a fixed cleaning schedule or a guaranteed strap lifespan, so clean as needed and dry the strap after exposure rather than relying on a set interval.

Recognize when the strap needs replacement
Cleaning can remove surface dirt; it cannot repair a cracked, cut, hardened, or severely deteriorated band. Stop wearing a strap that is no longer safe, and check the model number before looking for a compatible replacement band or contacting a Casio-authorized service option in your area.
A Casio restoration report published on August 29, 2023, discusses how sweat absorbed in a band and left there during long storage can worsen hydrolysis, and notes that rinsing after sea use can help extend band life. This is repair-context commentary, not a promised lifespan or guarantee for every resin band. Casio’s US restoration page describes a limited program that ran from October 1 through November 30, 2022; it is historical, not evidence that the program is currently available.
