Q. I have spots on my carpet that disappear when cleaned, but gradually come back over a two week period. How can I correct this?
A. Reoccurring spots crop up when moisture activates residue concealed at the base of the carpet. Wet cleaning, and sometimes low moisture cleaning, produces capillary action. Excessive and/or dormant spills are then drawn to the surface. If your carpet warranty allows, bonnet cleaning with an encapsulation cleaner immediately following extraction will normally correct the problem. Or, bonnet clean a few days following cleaning. Low moisture cleaning prevents much of the wick-back. However, the spill is still residing untouched on the backside of the carpet.
About 30-years ago, I was shocked to observe the results after cleaning a carpet at a car dealership. It actually looked worse on Monday morning. Apparently all the grease tracked in had been spot cleaned by the employees using copious amounts of cleaner. The grease spills were no longer visible. But, sufficient residue was lurking at the base of the carpet or even on the backside, waiting to resurface.
Another corrective treatment requires placing a white towel over the spot immediately after cleaning. Then, place a weight (20-30 lbs.) on top of the towel and leave 24-48 hours. To absorb spots reoccurring at a later time - apply an encapsulation cleaner, blot with towel, reapply cleaner and then place towel and weight overnight. One thing about reoccurring spots: they are correctable. Don’t give up; even a big-gulp is removable.
