How to use GetChildren() on a chracter?

I am not familiar with how to remove accessories but here it is on the wiki: http://wiki.roblox.com/index.php?title=API:Class/Humanoid/RemoveAccessories

Also to change the parts to transparency 1 in a model or character model or whatever, just insert this script in a model of your choice:

local sp = script.Parent --The model you insert the script into

function trans()
	for _, child in pairs(sp:GetChildren()) do --Gets the children inside the model
	child.Transparency = 1 --Every Child in the model gets set transparency to 1
end
