Cloudy glasses that clear when wiped with vinegar; etching marks on glassware.

Safety first: Handle chemicals with gloves and eye protection.

Step-by-step checks:

• Review detergent settings: Consult your chemical supplier to reduce detergent concentration to the minimum effective level.
• Check water softness: If a softener is installed, verify it is not over-softening the water. Adjust hardness to the range recommended by CMA and your chemical provider.
• Verify wash temperature: Confirm wash tank temperature is within CMA’s specified range. Overheating can accelerate etching.
• Evaluate glassware: Some low-quality glasses are more prone to etching. Test with a small batch of higher-quality glassware.

Note: Etching is permanent damage; focus on preventing further deterioration by adjusting chemistry and conditions.
