How to properly clean and shave floor carpet?

[InjectTheVenom]

Underneath are a number of pics that show my floor carpet, how and with what can I get it cleaned thoroughly in such a way that the color will look fresh, bright and uniform grey again?









How to shave this ruffled seam back to normal again?







Same for this rather scuffy looking patch?

Buy a new carpet or shampoo and jetwash that one.

after its dried, spray it grey. As for the shaving I think you'd leave bald spots as it looks like the "twist" has been pulled.

Jet wash with a good detergent, I use a traffic film remover do this.

Repeat several times you will see when the dirt stops lifting then let it fully dry, short of a new carpet thats about it.
