Teacher: Now, understand the problem? Solve this instance: [header] How to bleach linen [title] Soak the linen immediately. [step] For linens with stains, it is best to set them soaking as quickly as possible when you first notice the stain. Treating the stain quickly will help avoid the stain setting and becoming harder to remove later. <sep> (A) [substeps] To give the linen a faster recovery time, place the linen in a large bucket or basin of warm water for the first 24 hours. Label the bucket with the name of the item. (B) Soak the linen 30 minutes after moving from the previous step to the next. [title] Scrub the stain with a soft, rag-like sponge. (C) Put the linen in a bucket or tub that is completely clean and add water. Allow to soak for at least 2 days, but you can also allow linens to soak longer. (D) Toss the linen to remove it before you begin to bleach it. [substeps] Some color-resistant fabric or another type of absorbent material will need to be soaked, even if you plan to color-wash the linen.
