What can't you clean?

Answer 1

You typically can't clean certain delicate items, such as antique fabrics or intricate electronic components, without risking damage. Additionally, organic materials like mold can be challenging to fully eliminate, as they may require specialized treatments. Some stains, such as those from permanent ink or certain dyes, may also be impossible to remove completely. Lastly, cleaning can’t restore the original condition of items that have suffered irreversible wear or aging.
