Keep them out of normal use until appropriate cleanup advice is obtained. Porous materials and electrical items may require different responses.
What the observation means
A quick wipe does not establish that every item is safe. Do not carry contaminated boxes through the home unnecessarily or place them in the engineer's working route.
A useful next step
Explain the extent of the spill when arranging assistance and keep people away. The appliance repair and cleanup of belongings are separate tasks. Avoid operating any wet electrical item or using household fans and heaters around unresolved wet equipment.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
