Which type of spatula should be used when working with corrosive materials?

When working with corrosive materials, using a rubber spatula is appropriate because rubber is resistant to many chemicals, which reduces the risk of the spatula being damaged or contaminating the substances being handled. Rubber offers both flexibility and durability, allowing for efficient mixing or transferring of materials without the concern of corrosion that might affect metal tools.

Other types of spatulas, such as metal, are often not suitable for use with corrosive substances, as they can corrode or react negatively with certain chemicals, leading to potential contamination and safety hazards. Wooden spatulas may absorb liquids and chemicals, which could compromise their integrity and not properly clean after use. While plastic options may also be appropriate for some situations, rubber generally offers better resilience against a broader range of corrosive substances, making it the ideal choice in this context.
