How can you tell if the carpet has been cleaned?

You can tell if a carpet has been cleaned by checking for visible signs such as a lack of stains, a fresher appearance, and a noticeable absence of dust or dirt. Additionally, a recently cleaned carpet may have a slightly damp feel and emit a clean, pleasant scent. If the carpet fibers are more upright and fluffy, it’s also a good indicator of cleaning. Lastly, check for any cleaning residue or discoloration, which may suggest improper cleaning.
