I’ve dealt with plenty of wine stains during bond cleans, and I find the first step is usually more important than the cleaning product itself. If the spill is fresh, blot it with a clean white cloth and avoid rubbing, as rubbing can push the wine deeper into the carpet or spread it further.

For an older stain, I would first identify the carpet or fabric type and test any cleaning solution on an inconspicuous area. Some carpets can react badly to strong DIY treatments, particularly coloured or delicate fibres.

For stubborn wine stains, professional hot water extraction or steam cleaning can be much more effective because it removes the loosened stain rather than simply treating the surface. I’ve found this especially useful when dealing with rental properties where the carpet needs to be presentable for the final inspection.

We (https://www.bondcleaningservice.com.au/) regularly come across this kind of issue during end of lease cleaning, so I’d always recommend treating the spill as soon as possible and being cautious with household chemicals. 

The best technique for removing wine stains from carpet depends on whether the stain is fresh or dried. Here’s a step-by-step guide:

For Fresh Wine Stains:

1. Blot Immediately – Use a clean, dry cloth or paper towel to blot (not rub) as much of the wine as possible. Work from the outside in to prevent spreading.
2. Apply Club Soda – Pour club soda over the stain and continue blotting. The carbonation helps lift the stain.
3. Use a Vinegar Solution – Mix 1 tablespoon of dish soap, 1 tablespoon of white vinegar, and 2 cups of warm water. Dab the solution onto the stain with a cloth.
4. Blot with Cold Water – Use a fresh damp cloth to blot and remove any residue.

For Dried Wine Stains:

1. Rehydrate with Warm Water – Lightly dampen the stain with warm water to loosen the dried wine.
2. Apply Baking Soda Paste – Mix 1 part baking soda with 3 parts water and apply to the stain. Let it sit for 15–20 minutes before blotting.
3. Hydrogen Peroxide & Dish Soap – Mix equal parts hydrogen peroxide and dish soap. Apply, let sit for 10–15 minutes, then blot and rinse.
4. Steam Cleaning (For Tough Stains) – A professional steam cleaner can help extract deep-set stains.

If the stain persists, a professional carpet cleaning may be necessary.
