How do we feel about cast iron citrus juicers?

Real-world user experience with a cast iron citrus juicer:

1. Core Advantages: Maximum Durability

Century-long lifespan: Old-fashioned cast iron machines (no moving parts) can last three generations without breaking down; its juice-pressing power surpasses modern stainless steel.
Rock-solid stability: Weighing ≥2kg, it doesn't wobble when pressing grapefruit, eliminating the need for a grip.

2. Major Drawbacks

Extremely heavy: Difficult to hold with one hand; elderly users should be cautious (risk of injury to feet/countertop).
High risk of rust: Rust appears on fruit juice residue within 6 hours, requiring immediate baking and oiling for maintenance (see maintenance table below).
Outdated design: No filter → juice and pulp mix, requiring secondary filtration.

3. Usage Scenarios

4. Rust Prevention and Maintenance Tips

Emergency Rust Removal: Rub the rust layer with coarse salt and lemon peel → Dry over an open flame → Apply linseed oil (olive oil attracts ash).
Daily Maintenance: Scald with boiling water immediately after juicing → Dry with residual heat from the stove → Apply a thin layer of beeswax to lock in the rust.
Cleaning agents to avoid: ** Baking soda (damages the oil film) ** Dishwasher (accelerates rust)
