These guidelines are intended to assist you in the proper care and hand-washing of your glasses. 

Materials:

• Dishwashing gloves (optional, but recommended for grip and protection)
• Mild dish soap (formulated for glassware or gentle on hands)
• Large basin or sink with ample space for each glass
• Soft, lint-free dishcloths or microfiber cloths
• Air-drying rack (wire or plastic, with slots to accommodate various glass shapes)

Pre-Washing:

• Remove any debris or leftover beverage residue from the glasses by rinsing them with warm water.
• Inspect for cracks, chips, or damage. Discard any glasses with imperfections, as they may break or shatter during washing and cause injury.

Washing:

1. Fill the basin with warm water. Avoid using hot water, as it can cause the glass to expand and become more susceptible to breakage.
2. Add a few drops of mild dish soap. Opt for a soap specifically designed for glassware or known for being gentle on hands. Avoid using harsh detergents or abrasive cleaners, as they can dull the finish.
3. Don your gloves if using them. This provides extra grip and protects your hands from hot water or potential breakage.
4. Wash each glass individually. Submerge the glass completely in the soapy water, holding the base for stability.
5. Gently cleanse the entire glass, both inside and out, using a soft dishcloth or microfiber cloth. Pay particular attention to areas that may harbor residue, such as the rim, base, and stem.
6. For hard-to-reach areas like the interior of a champagne flute, you can carefully swirl a small amount of soapy water inside the glass. *Avoid using abrasive sponges or brushes, as these can scratch the delicate surface.

Rinsing:

1. Rinse each glass thoroughly with clean, warm water. Hold the glass by the base and tilt it at an angle to allow water to flow freely through the entire glass.
2. Perform a final rinse with cool water to eliminate any soap residue and achieve a sparkling finish.

Drying:

1. Gently shake off excess water from each glass.
2. Air dry the glasses completely on a clean drying rack. Place the glasses upside down on the rack to allow for proper ventilation and prevent water spots. *Avoid using towels or tea towels to dry the glasses, as these may leave lint or streaks on the surface.

Safety Precautions:

• Always handle your glassware with care. Mouth-blown glasses are delicate and can break easily if dropped or bumped.
• Avoid placing excessive pressure on the stems or rims of the glasses while washing.
• Be mindful of temperature changes. Avoid exposing your glasses to extreme temperature fluctuations, as this can cause them to crack.
• Never stack wet glasses inside one another. This can cause them to stick together and potentially break when separated.
• Store your glasses carefully in a cool, dry place. Opt for a cupboard or shelf with dividers to prevent them from clinking together and chipping.

Additional Tips:

• For stubborn stains or residues, you can soak your glasses in a solution of warm water and white vinegar for 15-30 minutes before washing.
• If hard water stains are a concern, consider using a filtered water rinse or a commercial rinse aid designed for glassware.

By carefully following these guidelines and safety precautions, you can ensure that your glassware remains beautiful and functional for many entertaining occasions to come.

Maintenance:

• Ensure regular dishwasher servicing following manufacturer's guidelines
• Set water hardness level correctly; consider partial softening or full demineralization
• Top up with salt regularly to prevent lime stains
• Adjust water softener within a hardness range of 3 to 8
• Keep dishwasher components clean

Usage Tips:

• Pre-rinse items like pots, pans, plates, and coffee cups to prevent staining
• Rinse off high-protein residues before placing glasses in the dishwasher
• Rinse glasses after use, especially wine glasses, to prevent acid damage
• Place glasses carefully to avoid scratches and breakage; avoid corner placement for tall, narrow glasses

Product Care:

• Follow dishwasher manufacturer's instructions for settings, detergent, rinse aid, and salt
• Use special glass cages for added protection
• Use quality detergents and rinse aids
• Avoid overdosing detergents and refrain from using additional additives if already included
• Select delicate or glass-specific cycles with low temperatures

Post-wash Handling:

• Crack dishwasher door open after the cycle to release steam
• Wait for glasses to cool before removing them; handle by stem or base to avoid fingerprints
• Gently dry glasses with a tea towel if there's residual water on the rim or base

Given the delicate nature of the stems, these glasses necessitate specific care. To preserve their longevity and brilliance, please follow these drying and polishing instructions:

Drying:

• Place the goblet upside down on a clean, lint-free tea towel to air dry.
• Avoid fabric softener or starch on tea towels.
• Wait for glasses to cool completely.
• Hold the glass by the stem.
• Dry and polish the base first.
• Polish the goblet (inside, rim, outside) with a lint-free cloth, avoiding twisting motions.
