If you own a reusable fabric heated eye mask from OPTASE or Bruder, the two brands do not share one cleaning routine. Each company publishes its own care instructions, and the steps are different enough that following the wrong one could damage your mask. This guide lays out exactly what each manufacturer says, with nothing added beyond their own published pages.
Why OPTASE and Bruder don't share one cleaning routine
OPTASE and Bruder both offer reusable, fabric-based heated eye masks, but their manufacturers publish separate care instructions. OPTASE directs owners to wipe the mask rather than wash it support.optase.com, while Bruder directs owners to hand wash the mask in cold water Bruder. Mixing up these two routines, for example submerging an OPTASE mask or skipping the wash step on a soiled Bruder mask, goes against what each brand actually instructs. The sections below separate the two procedures clearly so you can match your mask to its correct routine.
OPTASE Moist Heat Mask: official cleaning steps
According to OPTASE's own support page, the Moist Heat Mask is designed for microwave heating only and should not be heated in an oven, steamer, or by submerging it in hot water support.optase.com. The same guidance covers cleaning: to clean the OPTASE mask, wipe it with a damp cloth and a small amount of unscented soap if necessary, but do not fully submerge it in water support.optase.com.
Drying matters as much as the wipe itself. After cleaning, the OPTASE mask must be allowed to air dry completely for a minimum of 24 hours before its next use support.optase.com. Skipping ahead to a new session before the mask is fully dry is not part of the manufacturer's instructions.
On replacement, OPTASE's guidance is condition-based rather than time-based: the OPTASE Moist Heat Mask should be regularly inspected and replaced if it becomes worn or damaged support.optase.com. There is no fixed calendar interval in this source; the trigger is visible wear or damage.
Bruder Moist Heat Eye Compress: official cleaning steps
Bruder's published FAQ sets a different standard. The Bruder mask must be hand washed only, in cold water with a mild detergent Bruder. Unlike OPTASE's wipe-only approach, this is a full hand wash, not a damp-cloth pass.
Bruder also specifies when washing is needed: the mask should be washed if it becomes soiled or is exposed to makeup, oils, or grease Bruder. So the wash step is triggered by visible soiling or contact with makeup, oils, or grease, rather than being tied to a fixed number of uses.
Drying time matches the 24-hour window used by OPTASE, even though the wash method differs: after washing, the Bruder mask must be air dried for at least 24 hours before reuse Bruder.
Replacement guidance for Bruder is also more specific than OPTASE's wear-based rule. Bruder recommends considering replacement after 6 months of daily use. Bruder. That is a calendar-based recommendation tied to daily use, distinct from OPTASE's "replace when worn or damaged" standard.

- When to clean: OPTASE's source does not give a specific soiling trigger beyond "if necessary." Bruder specifies washing when the mask is soiled or exposed to makeup, oils, or grease Bruder.
- Drying time: Both brands specify a minimum of 24 hours of air drying before the next use.
- Replacement trigger: OPTASE says replace when the mask becomes worn or damaged. Bruder recommends replacement after 6 months of daily use.
What these instructions don't cover
The cited care instructions are model-specific. OPTASE’s damp-cloth instruction does not specify a numeric water temperature. Follow the instructions supplied with your specific mask if they differ from the pages cited here.
If you're considering a different maintenance model
Everything above applies to fabric masks that rely on wiping or washing a pad you heat yourself. Beminda Steam Therapy Pro is a rechargeable, hands-free steam eye mask built around a different structure: a sealed reservoir rather than a washable fabric pad. Use only Beminda Eye Hydration Complex in the current Steam Therapy Pro reservoir, since that is the only liquid Beminda recommends for it. Its three current modes each run for 12 minutes; the warm modes include approximately four minutes of warm-up within that total. This is not a replacement for OPTASE's or Bruder's own care instructions, and nothing about OPTASE's or Bruder's published cleaning routines says anything about how a sealed-reservoir device performs. If you're weighing whether to keep maintaining a fabric mask or look at other formats, you may also find it useful to review comparing reusable and disposable heated eye masks or a buyer's checklist for rechargeable heated eye masks.
