Fabric Care Instructions

Generic Fabric Care Label Text (Universal) Care Instructions – Please read carefully before washing. Machine wash cold (30°C / 86°F) on gentle cycle with similar colors. Hand wash recommended for delicate fabrics using mild detergent. Do not bleach – avoid chlorine and oxygen bleach. Tumble dry on low heat; remove promptly to prevent wrinkles. Line dry in shade for best results (especially for natural fibers). Iron on low temperature (max 110°C / 2412°F) if needed; do not iron on print/embroidery. Do not dry clean – use only water‑based cleaning unless specified otherwise. Dry clean only – for structured or sensitive materials like wool, silk, or acetate. Do not wring or twist – squeeze out excess water gently. Wash inside out to protect surface design and color. Do not use fabric softener – it may reduce absorbency or damage coatings. Do not steam directly on embellishments. Professional wet cleaning is acceptable. Note: Always refer to the specific care label sewn into the garment (typically located inside the back neck or lower left side seam) as some items may have unique requirements. When in doubt, choose a milder cleaning method.
