What Are The External Cleaning Methods for Fume Hoods

The external cleaning method of fume hoods is an important step to ensure their normal operation and provide a safe experimental environment. The following are the detailed external cleaning methods:

First, preparatory work

Turn off the power: Make sure the power of the fume hood is turned off and all connections are disconnected to prevent electric shock accidents during the cleaning process.

Personal protection: Wear appropriate personal protective equipment, such as gloves and goggles, to ensure your own safety.

Prepare cleaning tools and detergents: Prepare non-woven fabrics, neutral detergents, spray bottles and other cleaning tools and materials. Avoid using acidic or alkaline cleaners to prevent damage to the materials and internal components of the fume hood.

Second, cleaning steps

Wipe the surface: Use a damp cloth or non-woven fabric dipped in neutral detergent to wipe the external surface of the fume hood, including the glass, metal and plastic parts. Be careful to avoid liquids from entering the interior of the fume hood.

Rinse with clean water: Wipe clean again with clean water to ensure there is no residual cleaner on the surface.

Special stain treatment: For special stains on the exterior of the fume hood, such as splashed chemical liquids, etc., appropriate cleaning agents should be used immediately for removal, and relevant safety operation procedures should be followed. Avoid using cleaning agents that may cause corrosion or damage to the materials of the fume hood.

Third, precautions

Avoid using corrosive cleaners: As mentioned above, do not use acidic, alkaline or strongly corrosive cleaners to prevent damage to the external material of the fume hood.

Regular cleaning: It is recommended to regularly clean the exterior of the fume hood to maintain its good appearance and performance.

Safe operation: When cleaning the fume hood, please ensure that the operator has relevant safety knowledge and operational skills. Following the correct cleaning method guidelines can effectively protect the service life and performance of the fume hood.

Fourth, cleaning methods for different materials

Stainless steel material: For the removal of stubborn stains or spots on the surface of stainless steel, it is recommended to use MEK (methyl ethyl ketone) cleaning. After cleaning, rinse immediately with clean water and liquid detergent, and then clean with polyurethane cloth or sponge. Avoid using chlorine-containing cleaners to prevent rusting of the stainless steel surface.

Solid core physical and chemical board countertop: It is recommended to clean it with warm water, acetone or mild detergent. For stubborn stains, hypochlorous acid can be dropped onto the contaminated surface of the physical and chemical board and then washed with water. Avoid using cleaners containing abrasive components to prevent surface damage.

For the spray painting and baking parts: Wipe with fine cleaning liquid and avoid contact with sharp objects.

In conclusion, the external cleaning methods of fume hoods need to follow certain steps and precautions to ensure their normal operation and provide a safe experimental environment. At the same time, different cleaning methods and cleaning agents should also be adopted for the external surfaces of fume hoods made of different materials.
