Secretion stains cause a risk of infection which is why they need to be removed immediately.
Thorough hygienic practices are part of patient safety. Instructions: wear disposable gloves. Pour disinfectant on the secretion stain, making sure to use enough to cover it completely. Wipe the area clean with a disposable/paper towel and place the used towel in a bin bag. Remove the gloves and place them in a bin bag. Disinfect your hands.
