NANO-TEX® RESISTS SPILLS CLEANING PERFORMANCE
STAIN TESTING METHODOLOGY:
1 gram (1ml) of staining material is applied to the fabric and allowed to sit for 24 hours. Excess liquids are removed with a dry towel; excess solids are removed by scraping or brushing with a soft bristle brush. If pre-cleaning does not completely remove the stain (grade < 5), then the fabric may be cleaned with the following: a) water; b) water-based detergent; or c) solvent cleaner. Fabric is then graded according to the following scale:
| GRADE | DESCRIPTION |
| 5 | No stain. Not objectionable in any way. |
| 4 | Slightly stained. Visible under close observation but not visible to casual observer. |
| 3 | Noticeably stained. Visible to casual observer and may be objectionable. |
| 2 | Considerably stained. Clearly visible and probably objectionable. |
| 1 | Heavily stained. Clearly visible and definitely objectionable. |
