Yes, 1095 spring steel is not stainless and is susceptible to rust and corrosion if not properly cared for. It is a high-carbon steel that contains a significant amount of carbon but lacks the chromium content that provides stainless steels with their corrosion-resistant properties.

To prevent rust and corrosion on 1095 spring steel, it's important to take proper care and maintenance measures. Here are some steps to help minimize the risk of rust:

1. Keep the steel dry: After use or exposure to moisture, ensure that the steel is thoroughly dried. Moisture and humidity can accelerate the rusting process, so it's important to remove any moisture promptly.
2. Apply protective coatings: Applying a thin layer of protective coating, such as oil or wax, can help create a barrier between the steel and moisture in the air. These coatings can inhibit the formation of rust and provide some level of corrosion protection. It's recommended to use a corrosion-inhibiting oil or a specific metal protectant product.
3. Store in a suitable environment: Store the 1095 spring steel in a clean, dry, and well-ventilated area. Avoid storing it in damp or humid conditions, as this can increase the risk of rust formation.
4. Regular maintenance: Periodically inspect the steel for any signs of rust or corrosion. If any rust spots appear, remove them promptly using a non-abrasive method, such as gently scrubbing with a soft cloth or using a rust remover product. After removing the rust, reapply a protective coating to prevent further oxidation.
5. Oil regularly: Applying a light coat of oil, such as mineral oil or specialized blade oil, on the steel's surface can help maintain its condition and protect against rust. Regularly oiling the steel is particularly important if it's being stored for an extended period.

By following these maintenance practices and taking preventive measures, you can help mitigate the risk of rust and maintain the appearance and performance of 1095 spring steel.
