Can a mattress be hosed down?

It is generally not recommended to hose down a regular mattress, as excessive moisture can damage the mattress and its internal materials, leading to mold, mildew, and rotting. However, certain types of mattresses, such as waterbed mattresses or outdoor weather-resistant mattresses, can be hosed down appropriately because they are designed for such scenarios and have moisture-resistant materials.

For a standard innerspring or foam mattress, it's best to spot-clean spills and stains and use a mattress protector to protect it from liquids and spills.
