I did that but I burned the carpet completely good question

This sounds weird but I found it worked for me when I had a carpet with singed bits due to cigarettes (I have since successfully given up hoorah). Get a potato and cut it in half and rub the cut part hard on the surface of the singey burney bits and it comes up okay!!!!!! like magic. Go on give it a go.

You can try this, but be ready with a patch of carpet to replace in case it doesn’t work. Get a regular shaving razor and gently go over the area with it to remove the melted portion.

I would say have someone cut it out and replace it. but in most cases you will also be able to tell where the patch is atleast a little bit.
