There are many kinds of residue.
For example a low cost low quality carpet cleaning company may only rinse the carpet with water leaving behind a soapy residue that attracts soil.
This sticky soap attracts more dirt and grime which cause the stain to reappear.

Let it sit for a few minutes and then wash it off with cold water.
