Surface Sanitation, Wipedown, and Disinfection

How to wipe down surfaces for disinfection
Surface wipedown for cleanrooms.

1. Follow relevant site protocol (procedures for safety, contamination, etc.) and wear cleanroom gloves.

2. Fold wiper in mid-air into quarter folds (Fig. 1A). This will produce several clean surface areas and allow better contact with the surface to be wiped.

3. When wiping, hold the wiper so that the folded edge is toward the area to be wiped. Hold the unfolded edges in your hand. Group the unfolded edges between thumb and forefinger.

4. Use either a pre-wetted wiper or a dry wiper moistened with an appropriate cleaning agent. (Fig 2)

5. Wipe in one direction, overlapping wiped area by 10% to 25%.

6. Wipe from cleanest to least clean regions of the surface being wiped. Wipe systematically, for example, from top to bottom, far to near. (Fig. 3)

7. Keep track of which surfaces have been cleaned and which wiper areas are unused.

8. Always use the cleanest surfaces of the wiper. If re-wiping use a clean portion of the wiper, not the used wiper area.

9. Dispose of wipers according to site procedures.

Wiping Wet Spills

1. Identify the spilled liquid. Follow the Material Safety Data Sheet (MSDS).

2. Choose wiper and gloves that will not be degraded by the liquid.

3. For hazardous spills, wear two pairs of gloves and try to keep the gloves dry. Wear any other necessary protective gear.

4. Use dry wipers to wipe spills up immediately. Then clean the affected surfaces by following steps 1-9 in the “Cleanroom Wiping Guide” above.

5. Dispose of wipers according to site procedures.

Isolator Cleaning Guide

Preparation for Cleaning:

1. Wipe down gloved hands and cleaning products with wipers prewetted with 70% IPA and place the products in the pass-through.

2. Close the pass-through. Wait the prescribed amount of time for the pass-through to reach equilibrium.

3. Wipe gloved hands with 70% IPA; place gloved hands into the isolator gloves.

4. Open the interior door to the pass-through and bring all components into the isolator interior. Close the pass-through door. Wait for the prescribed amount of time for the isolator to reach equilibrium.

Cleaning the Biological Isolators and Laminar Flow Cabinets:

For surfaces not within arm’s reach, use the Isolator Cleaning Tool and mop cover moistened with IPA (Fig. 1).

For surfaces within arm’s reach, use a quarter folded wiper (Fig. 2) wetted with IPA (or use a pre-wetted wiper).

1. Begin by wiping the top surface (‘ceiling’) with care so as not to damage the filter, then proceed to the back wall, then the sidewalls and finish with the deck (Fig. 1).

2. Work from high to low, clean to dirty, dry to wet.

3. Wipe in straight, parallel, overlapping strokes (Figs. 1 and 2). 4. Change wiper surfaces with each stroke, and mop covers as needed.

5. Use IPA moistened swabs to clean the corners and small, tight areas.

6. Place the used, soiled wipers, swabs and mop covers in a disposal bag or place through the disposal port (if applicable).

Protocol for Hazardous Drugs Removal

Remove any excess liquid from the surface to be decontaminated using a sterile Texwipe dry wiper*. Discard the contaminated wiper in a manner consistent with the facility SOP.

  1. Spray the TexQ® TX650 cleaner and disinfectant on a sterile dry wiper*.
  2. Quarter fold a wiper. See Figure 1.
  3. With the nozzle on stream, not spray, pump the TexQ® TX650 trigger four or five times, until the wiper is well dampened, but not wet and certainly not dripping.
  4. Wipe the surface with the TexQ-wetted wiper, using parallel, unidirectional overlapping strokes. Use one wiper for each stroke (up to 40 inches in length). See Figure 3.
  5. Repeat Steps 2–5 using the same wiping technique at ninety degrees (90°) to the previous wiping direction.
