# Dishwasher safe

**Dishwasher safe: The item survives a normal dishwasher cycle. Some versions specify the top rack only.**

## What it looks like

A square box with plates or glasses inside and water droplets or diagonal spray lines falling on them. A variant shows the items on the top shelf only.

## What it means

A dishwasher is a harsher environment than a sink: water around 55–70 °C, high-alkalinity detergent and a long soak. Aluminium oxidises and goes dull grey, cast iron loses its seasoning and rusts, wooden handles split, and hand-painted or gilded decoration comes off the glaze. The top-rack-only variant exists because the heating element sits at the bottom, where plastics closest to it distort. Nothing about the symbol implies the item is heat-proof in general — many dishwasher-safe plastics are not oven-safe at all.

> Defined by Manufacturer declaration. Where a symbol differs between standards, the difference is described above rather than resolved — both versions are in circulation on real labels.
