If you have a carpet at home that has become messed up, you naturally worry about its longevity. You might think that the stain will ruin your carpet forever. My advice, though, is if you have spilt curry sauce, you get in touch with a carpet cleaning company. I would contact someone as soon as possible because the damage that has been done will become semi-permanent if you just let it bake in.
The best advice that I can give you is to hire a professional. The internet is loaded with DIY techniques that, to my eye, often do not work. Some even make the problem worse. Hire a pro, and they can get the carpet cleaned up for you. This saves any more damage being done and ensures your carpet can be restored without any needless risk.
