Yeah, no kidding. By trial and error it is a great learning experience but also costs also...AKA Mytee.
I was told over and over how using a spinner was the way to go with T&G and I was not happy using a vapor steemer because it took to long and was hard on my back. So, I finally gave in and bought a setup thinking I was on top of the hill. Come to find out, it sucked for me. It works great for others but sucked for me. Now something as simple as my other OP machine and a grout brush and I am on my way. To some, it may seem like a "hack" way to clean but the results are there. So, regardless of what a person uses. If it works for THEM. Great!
