Iv never used it on wood personally. (Mainly cause my shelves arnt wood ). But iv used 50/50 vinegar and water, mixed it up, and used it to clean down my shelves. Immediately followed by a very thorough rinsing. Dried em up very well, and put them back in the cage. However I'm a cautious one so i did over rinse to be sure, and i did this while the chins were asleep. So it it had some time before they relay came out to mess with it much.
