Is Swiffer Dangerous to Pets?

According to the American Society for Prevention of Cruelty to Animals (ASPCA), the cleaning agents contained in the Swiffer wet jet fluid do not contain chemicals in large enough quantities to be harmful to pets.

ASPCA engaged toxicology experts to do an independent review of the Swiffer wet jet fluid, and no antifreeze or any other chemicals dangerous to pets were found. The fluid is primarily water, with the addition of two propylene glycol compounds and a small amount of isopropyl alcohol. However, following label instructions and employing common sense when using this, or any other, cleaning product around pets is still necessary.
