How to remove a summoned potion?

I summoned a no gravity potion in my world and don't know how to remove it. Is there any command I can type to get it removed? I used this command to summon it:

summon minecraft:potion ~ ~ ~ {NoGravity:1,CustomName:"\"firewandwater\"",Potion:{id:"minecraft:splash_potion",Count:1,tag:{Potion:"minecraft:water"}}}

This answer is no longer valid and will be edited later.

Yes, you can use either a command to remove all lingering potions, or just the ones within a certain distance of your player.

To remove all area-effect-clouds:

kill @e[type=minecraft:area_effect_cloud]

To remove area-effect-clouds within a 10 block radius of the player:

kill @e[type=minecraft:area_effect_cloud, distance=..10]
