Sly, it sound's like you are taking good care of your guitar, keeping it wiped off before and after playing is 99% of the job, as far as lemon oil, in the U.S., you can get it about anywhere that sells furniture care products, I usally use Hope's Lemon Oil, it's silicone and wax free, I recently found out that Carvin sells it in a 4oz spray bottle, and I'm sure it's availble from other sources. Lemon Pledge and all the imitators, as long as they contain no silicone, won't harm anything, they are a little heavy on the wax, just keep it wiped down and don't let it build up. The villian to watch out for in any cleaning product is silicone, if it get's under the guitar's finish, thru a chip or knick, etc, it can cause the finish to start coming off and since it soaks into the wood, it makes refinishing difficult, silicone is slick stuff and paint won't stick to it, it's what causes "fisheye" in paint, ............
