Help with removing textures from certain parts only?

so I have a script and I want it to only remove textures from certain parts

--Var
--Script

for i, part in ipairs(workspace:GetChildren()) do
		if part.ClassName == "Part" then
		--Smooth Parts
		if part.TopSurface == "Weld" then
			part.TopSurface = "Weld"
		end
		
		if part.TopSurface == "SmoothNoOutlines" then
			part.TopSurface = "SmoothNoOutlines"
		end
		
		if part.TopSurface == "Hinge" then
			part.TopSurface = "Hinge"
		end
		
		if part.TopSurface == "Motor" then
			part.TopSurface = "Motor"
		end
		
		if part.TopSurface == "Glue" then
			part.TopSurface = "Glue"
		end
		
		if part.TopSurface == "Studs" then
			part.TopSurface = "Smooth"
		end
		
		if part.BottomSurface == "Weld" then
			part.BottomSurface = "Weld"
		end
		
		if part.BottomSurface == "Hinge" then
			part.BottomSurface = "Hinge"
		end
		
		if part.BottomSurface == "Motor" then
			part.BottomSurface = "Motor"
		end
		
		if part.BottomSurface == "Glue" then
			part.BottomSurface = "Glue"
		end
		
		if part.BottomSurface == "Inlet" then
			part.BottomSurface = "Smooth"
		end
		
			if part.BottomSurface == "Smooth" then
			part.BottomSurface = "SmoothNoOutlines"
		end
		
		part.Material = "SmoothPlastic"
		--Circle Studs Top
		local s = Instance.new("Texture")		
		s.Face = "Top"
		s.StudsPerTileU = 2
		s.StudsPerTileV = 2
		s.Parent = part
		s.Texture = "rbxassetid://161779908"
		--Circle Studs Bottom
		local s2 = Instance.new("Texture")
		s2.Face = "Bottom"
		s2.StudsPerTileU = 2
		s2.StudsPerTileV = 2
		s2.Parent = part
		s2.Texture = "rbxassetid://161779906"
		--Old Skybox
		local sky = script.Parent.Sky:Clone()
		sky.Parent = game.Lighting
		--Old Lighting
		game.Lighting.GlobalShadows = false
		game.Lighting.Ambient = Color3.fromRGB(165, 165, 165)
		game.Lighting.OutdoorAmbient = Color3.fromRGB(197, 197, 197)
		
		--Remove texture from spheres
		
		for i, part in ipairs(workspace:GetChildren()) do
		if part.ClassName == "Part" then
		if part.Shape == "Ball" then
		for i, texture in ipairs(workspace:GetChildren()) do			
			if texture.ClassName == "Texture" then
				texture:Remove()
			end
			end
			end
		end	
		end
		end
	end

any help is appreciated :)
