Cuprinol Garden Furniture RestorerPRICE: £13.24 (1lt)
Found in B&Q as a restorer for garden furniture, Cuprinol’s wood cleaner comes as a thick gel. Painted on to dry teak, it’s left for five minutes before being agitated with a brush, then left for another 10 before being rinsed off. It performed reasonably well. The gel is a useful thickness that avoids runoff and wastage.
