Removing cola: pick your surface
Cola is a sugar-based sticky stain, usually from a knocked can or an overflowing glass with ice. The chemistry stays the same wherever it lands — but the safe way to treat it changes completely with the surface, which is why each pairing below has its own guide.
Water-soluble
Water-based cleaning can dissolve this stain — method and temperature are what matter.
Heat sets it
Keep hot water, steam and dryers away until the cola is fully out — heat fixes it permanently.
Fresh vs dried-in
Fresh cola blots up easily — it is mostly water. What it leaves behind is the problem: sugar syrup that dries invisible, stays tacky, and collects soil until a grey shadow appears weeks later where the spill was. The caramel colouring also browns if left. Rinse properly even when the patch looks clean.
