Make football gloves sticky again by machine washing them. Many football gloves' stickiness is refreshed after being washed because dirt and grime are removed. The stickiness of football gloves is also enhanced when the gloves are spit on or wiped with a moist towel.
Keep excess moisture from remaining on the gloves. Once they are spit on or wiped with a moist towel, wipe the gloves dry or clap them together to remove extra moisture. Also, simply placing a piece of tape across a glove, then pulling the tape off can remove dirt and debris and help make a glove sticky again.
