Excellent and easy - if you figure it out
I read a lot of the other reviews that talked about extreme scrubbing. The first time I used this, 15ish years ago, I had the same issue, it was an amazing amount of hands and knees scrubbing.<br /><br />The second time, I allowed it to sit on the surface much longer before attempting to remove the wax. The problem is that it tends to dry out too quickly. So, I waited a few minutes until it started drying and obviously wrinkling up the old wax, then sprinkled/poured a lot of additional water on it.<br /><br />  The difference between leaving it for 2 minutes and leaving it for 15 minutes is remarkable. Very light scrubbing removed all wax very easily. The second big problem is removing it the resulting mess. Using towels or paper towels to sop it up is *brutal* and takes forever. I used my Bissell Spot Clean Pro wet/dry vac with just plain water in the tank, and it was remarkably easy. It's a good thing to have around, but if you don't, you can rent similar systems for one-time use. DO NOT put the remover directly in the tank, that's entirely unnecssary. The cleaner can spray the keep-alive water, but just use it for rinsing and sucking up the residue. My recommendation is to pour out the extraction tank without looking at it too closely, because it's disturbing how filthy that floor was and how much crud the wax has grabbed.<br /><br />  So - work in small sections (I did about 4x4 feet at a time)<br />  let it sit on the surface for as long as you can<br />  if it starts to dry prematurely, add water to keep it moist<br />  Scrub lightly with a stiff brush<br />  buy/rent a wet-dru vac and rinse with lots of clear water<br /><br />Do this, and it is a very low-impact and easy operation.<br /><br />  The results (both previously and now) are rather amazing and alarming. My floor did not look that bad - until I did the first section. The difference was astonishing, that thing was *filthy* after even normal cleaning and occasional mop n' glo. It was rather alarming, cleaning it made a huge difference in the appearance, and also in the brightness of the kitchen. I had put off doing this for a long time because it was such a pain the first time, but now, this is going to be once/year, just to keep it from building up like that again.
