Recommended Glassware Cleaning Procedures
• Washing machines may be used. Support racks on the washer must be well maintained. The support pins should be coated with a non-abrasive material to prevent metal to glass contact and scratching. • For manual washing, use only plastic core brushes that have soft non- abrasive bristles. Soft, clean sponges or other wiping materials may be used. DO NOT USE THESE BRUSHES OR WIPING MATERIALS WITH ABRASIVE CLEANERS. Keep them clean. Scotch Brite and similar scouring pads will scratch glass and should not be used. • Inspect glassware before each use and discard if scratched, chipped, cracked or damaged in any way. • Many commercial glass cleaners are available. Follow the manufacturer’s directions for the use of these products, since some are corrosive and can damage the glass. • Organic solvents are acceptable cleaning agents when conditions warrant their use. WARNING: • Do not place metal or other hard objects, such as spatulas, glass stirring rods, or brushes with metal parts, inside the glassware. This will scratch the glass and cause eventual breakage and injury. • Do not use strong alkaline products and hydrofluoric acid as cleaning agents; they are glass dissolvers and can damage the glassware and eventually cause breakage which can result in injury. • Do not use any abrasive cleansers, including soft cleansers (i.e. Ajax, Comet, Old Dutch, Soft Scrub, etc.), as these will scratch the glass and cause eventual breakage and injury. • Do not place hands inside glassware while wearing any jewelry, particularly diamond rings, as these will score the inside of the glassware and eventually cause breakage and injury.
