Our guide can also work for old tomato stains. If you’re trying to get rid of a lingering spot from spaghetti dinners past, you can skip step one and jump directly to step two. 

Pro tip: Allow soaking time for older stains. We recommend waiting at least 10 minutes between applying your cleaning solution and blotting it up.

Vinegar and baking soda can be effective for removing old carpet stains, although success may depend on the type of stain. There are two common methods for this process.

One method involves combining the ingredients directly on the stain to create a chemical reaction. First, pour a generous layer of dry baking soda over the stain. In a spray bottle, mix distilled white vinegar with 1 cup of warm water and a few drops of liquid dish soap, then spray this solution thoroughly over the baking soda. The mixture will foam as the acidic vinegar reacts with the basic baking soda, which helps loosen and lift the stain. Let this sit for a few hours until it dries, then wipe or vacuum up the residue and blot the area with a clean, dry towel. You can repeat the process if the stain persists.

An alternative method suggests using the ingredients separately. Start by sprinkling baking soda on the stain and letting it sit for 15 to 30 minutes before vacuuming it up. Next, blot the remaining stain with a solution of equal parts white vinegar and water, and then blot the area dry with a clean cloth.

The fastest way to soak up water in carpet is to use a wet/dry shop vac to draw out as much water as possible. Afterward, apply firm pressure to towels to sop up any remaining moisture, then liberally sprinkle baking soda over the carpet and let it sit for at least an hour before vacuuming it up. You can speed up the process by opening windows, using blower fans to create airflow, and running a dehumidifier. 

If your usually super soft couch feels crusty and rough after cleaning, it could be that you haven’t removed the cleaning product properly, you used too much, or you applied the wrong type. Always check the couch tags to select the right cleaning product, read application instructions carefully, and test on an inconspicuous corner. For fabrics such as microfiber, you can soften and fluff crusty fibers using a soft-bristled brush.
