Recommended Glassware Cleaning Procedures
28150R-6
6
• 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.
