We purchased a vacation home that had outdoor teak furniture that had weathered badly. We used this product and the original teak wood was wonderfully restored. At first I was pouring the cleaner on the teak, but that was wasting a LOT of the product, so then I started using a brush to apply. We live in a very dry, windy climate, so I had to work quick to apply the cleaner, then scrub it on, then wash it off -- when I the full 2 minutes for the cleaner to soak in, it was drying on the chairs! Once I got my system down, this worked great. However I did have to use 4 bottles to clean a small round table and 4 chairs, a bench that seats 3, a rectangular coffee table, and 4 large chairs. Highly recommend this product
