Six plus years using this Great Product.

We've been using this product during our 6 years of full time living in our motorhome. It is easy to transport and store. It is premeasured and most of the time the product has a refreshing smell. It does exactly what it is intended to do very well. We plan to keep using it indefinitely. Walmart has a great price on it. I had been ordering it from Amazon, but it got increasingly difficult to find plus it recently has been much more expensive from Amazon.
