| High solvent relative humidity |
Do not exceed 80% solvent relative humidity. This is especially important for cotton, wool and rayon due to their high absorption capacity. |
Determine source of moisture and resolve. Run loads of predried rags through 2 or 3 complete cycles. |
Rinse solvent and/or dryer |
| Damp fabrics |
Dry garments will adsorb moisture from a wet solvent more readily than wet garments will release moisture to a charged solvent that is dry. |
Process garments for the recommended cleaning time. Maintain recommended charge. |
|
| Hard and/or long extraction |
Pressure from centrifugal force and weight of the solvent is exerted on the fabrics |
Extract at the recommended time and speed |
|
| Overloading |
Crowded garments tend to crumple, ball, tangle and fold |
Do not exceed weight and bulk limits of machine |
|
| High drying temperature |
Especially true of synthetic fabrics. Heat sensitive synthetics become soft and pliable and can develop hard-set wrinkles when exposed to the weight of other garments. |
Maintain normal drying temperature (120°F to 150°F depending on fabric type) |
|
| Allowing warm or hot garments to remain in the hamper or tumbler for an extended period |
Promotes high heat, moisture and pressure |
Don't shortcut cool down cycle. Remove garments immediately and place on hangers. Do not allow them to remain in the hamper. |
