Why not? Because just like any other business they have an interest in putting out products for you to consume, not to improve your garden but to improve their bottom line! But if money is no object then...

I wipe all surfaces with a light bleach solution between grows. Cleanliness is key. Even if you recover with mylar you can still harbor spors and insects on the walls. Oh which is another reason for not using mylar - moisture can be trapped between the film and the wall providing a nice home for all kinds of ailments! Just my 2 cents. Take it or leave it.
