Why
The Microplane grater features a stainless steel blade (typically 420 or 430 grade) and a plastic handle (often ABS or polypropylene). Stainless steel is generally dishwasher safe, but the high heat and alkaline detergent can cause the plastic handle to warp, crack, or become brittle after repeated cycles. The blade itself may experience minor surface oxidation or dulling over time due to the harsh environment. Microplane's official care instructions recommend hand washing to preserve the sharpness and appearance of the blade and handle. The handle's printed logos or decals can peel or fade in the dishwasher. The blade is the only part that can withstand machine washing without significant damage, but the handle's integrity is compromised.
How do you wash Microplane Grater?
- Rinse the grater immediately after use to remove food residue.
- Use a soft brush or sponge with mild dish soap and warm water.
- Gently scrub the blade in the direction of the teeth to avoid cuts.
- Rinse thoroughly with clean water.
- Shake off excess water and dry immediately with a soft cloth.
- Store in a dry place, preferably in a protective sleeve or drawer.
What happens if you put Microplane Grater in the dishwasher?
After one dishwasher cycle, the grater may appear fine, but the plastic handle can develop micro-cracks or a chalky residue from detergent. The blade's sharpness may slightly diminish. After repeated washes (10+ cycles), the handle may become brittle and crack, especially at stress points. Printed logos will likely fade or peel. The blade may show minor rust spots or etching, though stainless steel is resistant. The damage is primarily cosmetic and functional: a cracked handle makes the grater unsafe to use, and a dull blade reduces grating efficiency. The grater will not be ruined after a single wash, but long-term durability is compromised.
