Forgive me as I am not a good writer but if you have ever made a mistake by leaving a hot iron on the carpet.
There is a cure.and I never knew this or my mum wouldnt have been so angry when I was younger for burning her carpet :)
The ultimate cure is
1.Invest in some baking and disposable cheap razors
2. Mix soda with hot water and washing up liquid.
3 While wet shave away at the burns untill all burn to desired effects
My carpet has no signs of a burn or a razer.
It could happen to you
