This is the BEST carpet cleaner, recommended to me by a professional carpet cleaning guy years ago. We have all hardwood floors, otherwise Iād have some in my cart now
Yeah this is the best, also same price at my local safeway.
I use this every single day with a house of 5 dogs. 
Absolutely necessary.
$5.98 at Lowes, $6.99 at Walmart

Not bad to keep a bottle around. I have used it on upholstered furniture, car seats an carpet and as a stain pretreat for clothing. Love this stuff. Would buy this but I actually have 3/4s of a gallon refill left.
