Ex Input:
[header] How to wash hockey gloves [title] Air dry the gloves for several hours after games or practices. [step] While you may not be able to wash your gloves right after you leave the rink, you should at least dry them. Take the gloves out of your hockey bag and place them on a drying rack, clothesline, or equipment tree so air can circulate. <sep> (A) After covering the gloves, let them air dry completely. Be mindful that you want to place them in a place that is moist for several hours prior to testing whether they need to dry. (B) [substeps] As a general rule, players should dry their hockey gloves no more than an hour before a game. This will allow the static build-up to overcome the bad coating and preserve the gloves for the hockey season. (C) [substeps] You may also place them in your home to air dry overnight after playing. Air drying uses natural heat, meaning you can still warm them and dry them evenly after 30 minutes without a problem. (D) Leave them for several hours or until they're completely dry. [substeps] Airing the gloves can prevent bacteria from growing on the gloves and will reduce their odor.

Ex Output:
D
