How do I revert a players costume to default?

I have had some issues with coding a costume reverting block, an invisible part that you walk through.

when entering a room through one way, it puts a hazmat suit on the player that enters using the codes below:

Colour

function onTouch(hit) 
local human = hit.Parent:findFirstChild("Humanoid") 

if human ~= nil then 
	if human.RigType == Enum.HumanoidRigType.R15 then
		print("Rig R15") 
		hit.Parent:findFirstChild("LeftFoot").BrickColor = BrickColor.new(106)
		hit.Parent:findFirstChild("LeftHand").BrickColor = BrickColor.new(106)
		hit.Parent:findFirstChild("LeftLowerArm").BrickColor = BrickColor.new(106)
		hit.Parent:findFirstChild("LeftLowerLeg").BrickColor = BrickColor.new(106)
		hit.Parent:findFirstChild("LeftUpperArm").BrickColor = BrickColor.new(106)
		hit.Parent:findFirstChild("LeftUpperLeg").BrickColor = BrickColor.new(106)
		hit.Parent:findFirstChild("LowerTorso").BrickColor = BrickColor.new(106)
		hit.Parent:findFirstChild("RightFoot").BrickColor = BrickColor.new(106)
		hit.Parent:findFirstChild("RightHand").BrickColor = BrickColor.new(106)
		hit.Parent:findFirstChild("RightLowerArm").BrickColor = BrickColor.new(106)
		hit.Parent:findFirstChild("RightLowerLeg").BrickColor = BrickColor.new(106)
		hit.Parent:findFirstChild("RightUpperArm").BrickColor = BrickColor.new(106)
		hit.Parent:findFirstChild("RightUpperLeg").BrickColor = BrickColor.new(106)
		hit.Parent:findFirstChild("UpperTorso").BrickColor = BrickColor.new(106)
		hit.Parent:findFirstChild("HumanoidRootPart").BrickColor = BrickColor.new(106)
	else
		if human.RigType == Enum.HumanoidRigType.R6 then
			print ("Rig R6")
			hit.Parent:findFirstChild("Torso").BrickColor = BrickColor.new(106)
			hit.Parent:findFirstChild("Left Arm").BrickColor = BrickColor.new(106)
			hit.Parent:findFirstChild("Right Arm").BrickColor = BrickColor.new(106)
			hit.Parent:findFirstChild("Left Leg").BrickColor = BrickColor.new(106)
			hit.Parent:findFirstChild("Right Leg").BrickColor = BrickColor.new(106)
		end
	end
end 
hit.BrickColor = BrickColor.new(106) --this is for bricks
end 
script.Parent.Touched:connect(onTouch)

Clothes Giver

db = false
Hazmat = script.Parent.Parent.HazmatSuit

function onTouched(hit)
	h = hit.Parent:findFirstChild("Humanoid")
	if h~=nil and db == false then
		db = true
		e = h.Parent:GetChildren()
		for i=1,#e do
			if e[i].className == "Shirt" or e[i].className == "Pants" or e[i].className == "ShirtGraphic" or e[i].className == "Accesory" then
				e[i]:destroy()
			end
		end
	end
	e = Hazmat:GetChildren()
	for i=1,#e do
		if e[i].className == "Shirt" or e[i].className == "Pants" or e[i].className == "ShirtGraphic" then
			e[i]:clone().Parent = h.Parent
		end
		db = false
	end
end
script.Parent.Touched:connect(onTouched)

All these codes work, but I included them as they may be of use in some way to solving the issue of removing them, when leaving the room through a different exit.

I have tried 3 main variations of code to achieve the resetting of the player's costume without re-spawning.

1 - this removes the hazmat suit, however the colours are not reverted and the clothing and accessories of the players do not return, plus when a new player joins the game, if any other player re-spawns then the will look like the player that joined the server most recently.

local Players = game:GetService("Players")
db = false
local function onPlayerAdded(player)
	id = player.CharacterAppearanceId
	print(id)


	function onTouched(hit)
		h = hit.Parent:findFirstChild("Humanoid")
		if h~=nil and db == false then
			db = true
			player:ClearCharacterAppearance()
			print("appearence cleared")
			player:loadCharacter(id)
			print("loaded")
			--player:LoadCharacter()
			db = false
		end
	end
	script.Parent.Touched:connect(onTouched)
end

for _, player in pairs(Players:GetPlayers()) do
	onPlayerAdded(player)
end
Players.PlayerAdded:Connect(onPlayerAdded)

2 (which I found on a similar article on this website, however this may be outdated) How to change character appearance without having them respawn? EDIT

--This will add the character model to folder name Characters in ServerStorage
game.Players.PlayerAdded:Connect(function(player)
    player.CharacterAdded:Connect(function(character)
        if game.ServerStorage.Characters:FindFirstChild(player.Name) == nil then
            character.Archivable = true
            wait(2)
            character:Clone().Parent = game.ServerStorage.Characters
        end
    end)
end)

--When player leaves game this will remove the character model so that game don't use too much space
game.Players.PlayerRemoving:Connect(function(player)
    local playerCharacter = game.ServerStorage.Characters:FindFirstChild(player.Name)

    if playerCharacter ~= nil then
        playerCharacter:Destroy()
    end
end)

--This function will get the character model remove current and change your player to that one and move that model cframe position to your position
function loadCharacterAppearance(player)
    local characterModel =   game.ServerStorage.Characters:FindFirstChild(player.Name):Clone()
    characterModel:SetPrimaryPartCFrame(player.Character.PrimaryPart.CFrame)

    player.Character:Destroy()
    player.Character = characterModel
    characterModel.Parent = game.Workspace
end

3 same as previous

--Use this instead of that custom function make sure to get the player instance.
--E.g local player = game.Players.PlaasBoer  That will get my player.

player:ClearCharacterAppearance()

--This function reset appearance when called.
--This function will add the player appearance just pass the player through the argument when using it.
function loadCharacterAppearance(player)
    if player.UserId then
        local theModel = game.Players:GetCharacterAppearanceAsync(player.UserId)
        for _, child in pairs(theModel:GetChildren()) do
            player:LoadCharacterAppearance(child)
        end
    end
end

I have tested this out on studio and from Roblox.com

If you have any advice on how to correct this, it would be much appreciated. Thanks

You can use what's called a HumanoidDescription.

You can create a new instance of it when a player enters the room and save their clothing, accessories, etc. to the HumanoidDescription.

Whenever they exit the room, call the function :ApplyDescription() on their Humanoid and pass in the HumanoidDescription.

This not only lets you save their appearance into a single instance, but it circumvents the entire process of modifying all of the body parts, removing the accessories, etc. It cleans your code up a whole lot.
