Washing AAMI Level 2 Gowns

Washing AAMI Level 2 Gowns

Now that you have gone reusable, how do you wash your AAMI Level 2 gown? 

Wash chemistry should be equivalent to the typical soiling and staining common to the individual user. Some special treatments may be required from time to time. The following information is intended to serve as a starting point for washing your reusable PPE garment. 

1. Segregate soiled items by blend, colors, soil content, and fabric/garment weight to avoid shortened garment life from overwash, physical damage and cross-contamination of garments.

2. Avoid surfaces and conveyances which would snag or damage garments.

3. Promptly mend/repair garments to avoid extending damage (tears, snags, holes). It is recommended that garments with extending damage be removed from service. If repairs are necessary, heat seal patching from the same material is the recommended process.

4. Do not overload washing equipment to avoid insufficient cleaning, rinsing, or excessive garment wrinkling. Generally, load at 50% to 70% rated capacity depending on washer pocket configuration.

5. Frequently check and repair inside of washers and tumblers for damage that can snag garments.

6. Check and adjust/repair water levels, leaking drains, and supply lines to avoid improper chemistry concentration and rinsing effectiveness.

7. Use chemistry commensurate with soil level and end-use of the garment. Certain soils may require special pretreatments.

8. Recommended wash temperatures of 140o F to 150o F, do not exceed 160o F.

9. Non-chlorine bleaches may be used as required for stain removal and sanitizing. Always adjust wash chemistry for optimum bleaching activity. Any bleach can cause color deterioration. Chlorine bleach is not recommended, but if used, always use antichlor in one of the final rinses. Never use chlorine bleach when the garment has nylon fabric components.

10. Do not use softeners or topical, anti-static finishes as they may mask the fluid-resistant properties.

11. Tumble dry with cool-down cycle to minimize wrinkling.

12. Tumbler temperatures should be achieved that result in garment temperatures of 240o F to 280o F maximum. Frequently check tumblers for overheating and hot spots. Unload immediately and hang or fold garments to minimize wrinkling.

13. All loads should be soured. Sour to pH range 5.5 - 6.0. Do not use rust preventive sours.
