Washing crystals, also known as laundry crystals, are typically added to a laundry load to freshen up clothes and towels. However, there are several synonyms that can be used interchangeably with this term. Fabric crystals and aroma beads are two examples of synonyms for washing crystals. Fabric crystals often come in different fragrances and have the same purpose as washing crystals: they add a fresh scent to clothes. Aroma beads are similar in that they are added to laundry to freshen up clothes and have a fragrant scent. These synonyms are useful for individuals who want to vary their laundry routine or want to try out new products that have similar functions.
