To clean a laminar flow hood, use a lint-free clean room tissue or a micro fibrous cloth
Spray cleaning fluid directly onto the wall surface, or soak your cloth or tissue in your cleaning fluid of choice.
Start with the back wall, cleaning top to bottom. Swipe side to side with overlapping lines
Next clean the side walls, again clean in a side to side motion from top to bottom, overlapping strokes.
Finally Clean the bottom using side to side motion from top to bottom, overlapping strokes like before
