Summarize this article:

Brushing the velvet will remove dirt and lint, and loosen any mats in the fabric. This prepares the fabric for treatment and can remove caked-on dirt before spot cleaning. When brushing accessories, make sure you’re getting into corners and areas where there might be hardware to remove dirt and lint. The suction will remove any dirt and lint, and the brush attachment will loosen up mats in the fabric to prepare it for cleaning. Be gentle and don’t push too hard on the fabric as you can crush the pile. To prevent further stains and dirt from damaging the fabric, you can vacuum your velvet once per week. You may need to add extra lemon juice to create more foam. You won’t be using any of the liquid portion of this mixture, so don’t worry about having excess liquid. If you’re cleaning the entire piece of furniture, you’ll probably need to add more baking soda and lemon juice as you work. Make sure there are a lot of bubbles while you’re mixing. If you need to, you can add more water and detergent to create the foam. Gently pick up some of the foam that was created by the mixture. You don’t need a large amount, just enough to cover the top of the cloth. You can remove excess foam with a dry area of the cloth. Let the area dry and brush it with the cloth or a clothing brush.  For furniture, you should apply the foam by wiping in long strokes with the nap of the fabric.  You should test this method in a small, inconspicuous area first, such as the inner lining or hem hem of a piece of clothing if it has velvet on it, or a non-visible portion of the furniture or accessory. Although the mixture might appear to dry quickly, give it some time to completely dry from the fabric and allow the pile of the velvet to return to its original form. Avoid using the item or piece of furniture during this time. If the stain is still present, apply another coat and allow it to dry again, repeating until the stain is gone. You can find protective coating for velvet furniture at department stores, furniture stores, or online. Make sure you’re misting the item by spraying at least 6 inches (15 cm) away from the fabric, rather than saturating it with the spray.  After the spray dries, wipe the furniture with a clothing brush or lint-free cloth to remove any mats or creases. Protective coatings made specifically for delicate fabrics, such as Scotchguard and Nano Protector, are great solutions for accessories that tend to get dirty quickly. You can also use furniture protector spray to ensure waterproofing for velvet shoes.  Applying a protective coating might void your item’s warranty, so make sure you check the care information before spraying the item with the solution.
Brush the item with a clothing brush or lint-free cloth before treating. Vacuum velvet furniture with the brush attachment. Mix 2 tablespoons of baking soda and ½ a cup of lemon juice to treat spots on furniture. Mix 1 tbsp delicate detergent and 2 cups of water to treat clothing and accessories. Skim the foam of the mixture with a lint-free cloth. Dab the foam onto to the spot using a lint-free cloth. Allow the item 3-5 hours to dry. Apply a protective coating to furniture or accessories to avoid new stains.
