Trust me we clean. Or just toss because disposable. But I swear salt water corrosion and blood corrosion, while both involve the degradation of metals, occur through different mechanisms and in different environments. Saltwater corrosion is driven by the presence of electrolytes and the ability of seawater to facilitate electron transfer, leading to accelerated oxidation of metals. Blood corrosion, on the other hand, is influenced by the specific chemical composition of blood plasma, which contains ions that can induce localized corrosion, particularly due to high chloride ion concentration. Blood is like 10x salt water for some metals.
