Write the next sentence in this paragraph:

How to clean velvet shoes
Blot up excess liquid with a microfiber cloth.
Microfiber cloths work well for blotting up stains before they set in because they're very absorbent. Use the cloth to lightly dab at the stained area to soak up some of the stain before it dries.

Choices:
[a]. Don't rub up too much liquid, as dabbing will damage the velvet. Blot the area again with a soft, lint-free paper towel.
[b]. Don't rub the material with the cloth because this can damage the shoe further. Mix warm water and bleach.
[c]. The cloth should not be dripping wet, making blotting the stain worse. Use a soft cloth dampened with distilled white vinegar.
[d]. Do this as soon as you can so that the stain will be as minimal as possible. If you don't have a microfiber cloth on hand when you notice the stain, try using something else absorbent, such as a regular cloth or a paper towel.
[d].
