General rules for linen
Linen is strong, absorbent and prone to shrinking, and all three matter here.
Strong means it takes handling and long soaks without complaint. Absorbent means a milk mark goes into the fibre quickly, so a cold rinse in the first minute is worth more on linen than on almost anything else.
Shrinking means the wash temperature is capped at around 30 C, which is convenient, because that is also below the temperature that would set the stain.
Check the label
Linen shrinks with heat and weakens with bleach. UK retailers specify 30 C or lower on a delicate or hand wash setting, a gentle non biological detergent free of bleach and brighteners, and no fabric softener because it coats the fibres and reduces breathability.

Linen is spun from flax and it is the most absorbent common clothing fibre.
It takes the stain in fast
Absorbency is why linen feels cool to wear and why a spill is in the fabric before you have found a cloth. Speed matters correspondingly more.
It shrinks
Retailers cap linen at 30 C or lower for exactly this reason, and note that most linen clothing is pre washed to limit it. High heat in a dryer shrinks it further and sets creases that are hard to press out.
Bleach weakens it
Chlorine bleach attacks the cellulose and leaves linen thinner and more prone to tearing at the folds, so an oxygen product is the right choice even on white linen.
It creases, which is not damage
Linen creases by nature. A creased area around a treated mark is not a sign that anything has gone wrong.
