Old stains – sometimes it’s easy to think of them like a cheap horror movie monster, given the way they keep showing up long after they’re supposed to have been destroyed. Or maybe they’re like annoying guests who, after you’ve finally got rid of them and have forgotten you ever had them, stop by again for another agonizing, prolonged visit. Whatever they remind you most of – monsters, annoying relative, or bad pennies – it seems like some stains have developed a nasty habit of reappearing on your carpet – despite many carpet cleanings – in a process called wickback. But what actually causes this to happen – what’s the science behind the annoyance?
In order to explain just how these stains come back, though, we need to know how they got there in the first place – and that of course can be traced to the original spill. Now, whenever the, let’s say, coffee was spilled, what you did in response help determined if there would be wickback. If you did your best to blot up the stain, trying to get up as much moisture as possible, you did well. If you just left the stain there to dry or poured water on it to fade the color – a no-no for carpet stain removal – you may be the reason behind the reappearance of the stain. You left a lot of liquid in the carpet and all of that water allowed the sediments to sink downward. And as it sank down, it worked it’s way into the lowest parts of the carpet, including the pad.
