My teak companion seat had deteriorated so badly in the garden that I feared it was beyond redemption. I came across Furniture Clinic on Amazon and thought I would give it a try. First I pressure-hosed the seat to remove much of the lichen and other debris clinging to the wood. I bought the full kit, which came with a high grade scrubbing brush, latex gloves and lint-free cloths, everything I needed. I followed the instructions and found the process far easier than I expected. The final result was astonishing. I cannot recommend Furniture Clinic highly enough.
