What materials are used to make cleaning sponges used for dishes?

I've read that some of the original sponges were made from the skeletons of real sponges

:P

I D K! i don't think that they are made from real skeletons but maybe from a different substance

y012f is correct that the original sponges were dead marine life but the new ones are synthetic, usually made of urethane foams or silicones. The composition varies somewhat depending upon the intended use; for example, a cosmetic sponge used for applying makeup would be different than those used for washing dishes.

Cleaning sponges used for dishes are typically made from a combination of synthetic materials. The two most common materials used are cellulose and polyurethane. Cellulose is derived from wood pulp and gives the sponge its absorbent and soft properties. Polyurethane, on the other hand, provides durability and helps the sponge maintain its shape.

To find out the materials used in cleaning sponges, you can start by checking the packaging or product descriptions of various brands. Look for keywords such as "cellulose" or "polyurethane" in the materials list or product descriptions. Manufacturers often mention the materials used as a selling point to highlight specific qualities of their sponges, such as absorbency or longevity.

If you don't find the information you need on the packaging, you can also visit the manufacturer's website or contact their customer service for further details. Additionally, online retailers or review websites may provide information on the materials used in specific cleaning sponges through product descriptions or customer reviews.
