For many Life Sciences workers wearing goggles is an essential part of their personal protective equipment (PPE) to protect themselves against harsh chemicals and the product from contamination.
However, working in goggles all day can result in them becoming foggy or steamed up which can be a hazard as well as an inconvenience. Fogging occurs when there are variable temperatures, humidity, change in body temperature or even from wearing a face mask. For all of these conditions it is important to be able to find a comfortable solution that can withstand fogging whatever environment you are in. It is also advised to use a goggle with an anti-scratch coating to further prolong the life of the lenses.

WASHING BIOCLEAN™ AUTOCLAVABLE GOGGLES PRIOR TO AUTOCLAVING
The BioClean™ range of autoclavable cleanroom goggles are designed to be autoclaved by hot steam at 121°C for 30 minute cycles. The goggles are very robust and can be washed prior to autoclave in water at a temperature range of between 60°C to 121°C. A mild detergent can be used as long as it is diluted in the water first – we suggest 100ml of household dish washing detergent for every 5 litres of deionized water.
Place the goggles inside a bucket of mild detergent prepared and mixed as suggested above.
Let the goggles soak for 2 minutes in the soapy solution
Remove the goggles and rinse thoroughly with clear, clean deionized water to remove any residual detergent and avoid streaking. Use fresh deionized water for each rinse.
After washing and rinsing, we recommend that the goggles are dried with cleanroom quality POLYESTER wipes before putting them into the autoclave. This would also help remove any other remaining potential deposits from the detergent.
Please note it is important that the water used to wash and rinse the goggles should be deionized, demineralized or distilled water. If normal untreated tap water is used it may have mineral deposits in it that will become apparent when autoclaved, and these may be deposited on the lens, potentially causing them to be damaged.
