oh! dear, not sudocrem. oops!
i had the same problem luckily in my own home a few years back, the whole tub and twin boys going mad on a dark green nylon multi loop pile, yikes,
ok, first off i did before doing carpet course or any machines is:
i phoned sudocrem pmsl. but i did.
remove kids.( a must) time consuming job now.
make up a hot bowl water with oxi powder.
lather the bubbles in gently,
leave for a few mins,
pat and blot dry,
repeat, all above a few times.
brush carpet when dry,
if slight light shading still appears, get the guys in to steam it , the oxi breaks down most of the alcohol which is in it, but it is heavy in wax, so best treating carpet as the same as you treat wax,
suppose you could freeze it off, the warmer it is the more it spreads.
anyway no doubt some one will jump down my throat but i managed to get it off my way.
good luck
