Our fingerboard cleaning products including XLR8, Hydrate, and Lemon Oil are intended for use on fingerboards made of dark, unfinished woods only. They should not be used on light wood fingerboards—such as maple, or any finished fingerboards.
Our body cleaning products like those contained in our Instrument Care Essentials pack (including detailer, wax, and spray cleaner) can be used safely on instruments with a lacquered finish. They should not be used on matte finish instruments. Generally, Instrument Care Essentials are also safe for use on nitrocellulose finish instruments, but we do recommend testing the products on a small spot on the back of the instrument before using them on your entire instrument as chemicals used in finishes can vary from manufacturer to manufacturer.
