Fantastic service - the nicest people you could meet and a great job. Natural chemicals do not leave any noticeable smell during or after cleaning. Every spot came out. I was having terrible allergies - stuffy nose, red itchy eyes, even the cat was sneezing, and after a carpet cleaning they're gone. They also cleaned the floors & mats in two cars and took away two musty rugs for a more thorough clean. Cannot recommend Daly City Carpet Cleaning Experts highly enough.
