How do I make a script remove all accessories when the player joins?

I am trying to remove all the accessories from the player when they join however, It doesn't work. This is the code I've tried.

game.Players.PlayerAdded:Connect(function(player)
	local humanoid = player.Character:WaitForChild("Humanoid")
	local accessories = humanoid:GetAccessories()
	while accessories do
		accessories:Destroy()
	end
end)

Thanks in advance.

You are on the right track. Something you can try is to make a server script in serverscriptservices that says the following:

game.Players.PlayerAdded:Connect(function(plr)
     plr.CharacterAdded:Connect(function(char)
          for i,v in pairs(char:GetChildren()) do
               if v:IsA("Accessory") then
                    v:Destroy()
               end
          end
     end)
end)

This script will destroy any accessories the player has when its character is reloaded, such as when the player dies. If you want it for only when the player joins you'd revise the script:

game.Players.PlayerAdded:Connect(function(plr)
     local changed = Instance.new("BoolValue")
     changed.Parent = plr
     changed.Name = "IsDifferent"
     changed.Value = false
     plr.CharacterAdded:Connect(function(char)
          if plr.IsDifferent.Value == false then
               for i,v in pairs(char:GetChildren()) do
                    if v:IsA("Accessory") then
                         v:Destroy()
                    end
               end
               plr.IsDifferent.Value = true
          end
     end)
end)

I hope this answers your question

Edit:

I have found the solution! There is a tutorial provided by roblox right here on how to do this. You'll have to scroll down a bit but it is there. You can edit this script using the suggestions I provided before.

local Players = game:GetService("Players")

Players.PlayerAdded:Connect(function(player)
	wait(2)
	local char = player.Character
	if char then
		local childs = char:GetChildren()
		for i,v in pairs(childs) do
			if v:isA("Accessory") then
				v:Destroy()
			end
		end
	end
end)

Detailed Explanation:

So basically what is happening in this script is that when the player joins the game it will get its character, a wait is added so we make sure we get the player, then we check if the character exists, we used :GetChildren to create a table that contains the children of the character (Head, UpperTorso, Hair, etc...).

Now we need to go through the table, so for i ,v in pairs. While going through the table if the item :isA("Accessory"), what this does is that it checks the class of the V (which is the child that we got from the character) and it filters it so now we got all the Accessory then we Destroy them .
