    Frequently Asked Questions

    FAQs

    How do you know that SpongeBath kills odor-causing bacteria?

    SpongeBath has been independently tested by a GLP laboratory in New Jersey to kill >99.99% of odor-causing bacteria, such as E.coli 157 and Staph, when used as directed. As SpongeBath is not yet registered with the EPA, we can't make any claim that SpongeBath is a sanitizer or disinfectant.

    When will I receive my Order?

    We process your Order as soon as possible after receipt. Orders will be shipped out within three business days. Your Order will be shipped to you using the shipping method you select during checkout.

    How does the SpongeBath System work?

    SpongeBath is the first dual-purpose sponge holder that both cleans and stores your sponge -- simple, effective and easy to use. SpongeBath’s patented “paddle action” method draws our patent-pending cleaning solution deep into the micro-crevices of the sponge -- cleaning it and killing 99.99% of odor-causing bacteria so you can always have a fresh, clean sponge.

    What is the Concentrated Cleaning Solution made from?

    SpongeBath's patent-pending citric acid concentrated cleaning solution is composed of food-grade ingredients, safe when used as directed. Because it is concentrated, avoid contact with your eyes and skin as it may cause irritation. Use only as directed.

    What kind of sponge can I use with SpongeBath?

    SpongeBath works with all household sponges up to 4.75” in length including synthetic, natural, cellulose and scrubber sponges. Do not use with bathing, make-up or any other sponges for personal use.
