How should I care for clothes labeled as both non-dry cleanable and non-washable in water?

One specifies a washing method, while the other blocks washing itself. There are products that instruct to care for them with dry cleaning but not to put them in a dryer^[1], and going one step further, there are also products that instruct to be sure to dry clean separately and avoid both dryers and irons due to concerns about color transfer and staining^[2]. On the other hand, there are products labeled as unable to undergo both dry cleaning and washing in water because discoloration or deformation may occur^[3].

The issue is the third case. We have not yet confirmed separate brand instructions regarding how to actually care for such products. Generally, clothes for which both methods are blocked often have elements that can react to either water or solvents, such as adhesives, coatings, decorations, or combinations of materials with different properties. Therefore, the direction of care tends to focus on not creating stains rather than washing — airing out after wearing without immediately folding to remove odors and moisture, lightly brushing off surface dust with a dry cloth, and pressing with a dry cloth to absorb partial stains instead of rubbing and spreading them. For storage, it is recommended to avoid direct sunlight and moisture, and hang them loosely so that pressure marks are not left behind. If there is a stain that is difficult to handle, the remaining option is to inform a professional cleaner of the material composition first and consult with them. However, it has not been confirmed whether these details apply directly to individual products.

The label for separate dry cleaning also becomes easier to understand when read in the same context. Generally, for clothes with the possibility of color transfer, risk arises the moment they are mixed with other laundry, so the condition of not putting them together becomes key rather than the process itself.
