Recently bought garden bench from B&Q. It is made from Roble wood which I think is a type of oak. Says on packaging do not use oils but treat with Roble Aftercare Wax which B&Q do not have and haven't really a clue as to what to use, (have suggested I use a stain!) Feel like giving it back but I like it and it was fairly cheap. Anyone with any suggestions as to treatment which will help preserve it for a reasonable length of time but will keep its present appearance (so don't really want to use varnish). Thanks, Col
