What to do — and not do — when a dry-clean-only garment is stained
The procedures in the Ohio stain-removal series do not apply to garments labeled dry-clean only, and this short sheet exists to draw that line clearly. Clothing labeled 'dry-clean' or 'professionally dry-clean' should be taken to the cleaners promptly when it is stained, with the fiber content of the clothing and the type of stain identified for the cleaner if they are known. Promptness matters as much as restraint: a fresh stain the cleaner knows about is a routine job, while the same stain home-treated, heat-set or aged can become permanent.

The procedures described here do not apply to garments labeled dry-clean only. Clothing labeled "dry-clean" or "professionally dry-clean" should be taken to the cleaners promptly. The fiber content of the clothing and the type of stain should be identified for the cleaner. Even professional cleaners cannot remove all stains. The cleaner will usually warn you if the stain cannot be removed, but sometimes this is difficult to predict. Dye stains on colored fabrics are an example of stains that may not be completely removed.

A dry cleaner can choose solvent, time and technique for a known stain on a known fiber far more precisely than for a mystery mark. Point out the stain at drop-off, name what caused it if you can, and mention anything already applied to it — an undisclosed home treatment is the most common reason professional treatment fails, because the cleaner then works against two problems. Pinning a short note to the garment preserves the information if staff change between drop-off and cleaning.
Dry-clean-only status usually protects something specific: a water-sensitive dye, a structured interfacing, a delicate trim, or a fabric such as silk or wool that water and home solvents can distort. The stain may be removable while the garment is not washable — which is precisely the cleaner's expertise. The few dollars saved by a home attempt are rarely worth a ruined tailored garment, and this sheet's advice is correspondingly absolute.
The series says no: its procedures apply to washable fabrics. Home treatment risks the dyes, structure and trims that made the garment dry-clean-only in the first place.
Promptly — fresh stains are the cleaner's easiest work, and delay plus heat can set a stain before professional treatment ever begins.
What the stain is, what the fiber content is, and anything that has already been applied to it. That information decides the cleaner's solvent and method.
