Lemon Pledge is about the worst thing you can use next to silicone.
Please, use only raw linseed oil. I use 99% isopropyl for cleaning when needed then the linseed.
Pledge and silicone-based products leave gunk on and in the wood that cannot be removed and effectively ruins the wood.
I have guitars that are 60 years old and guitars that are 5 years old. Rosewood, ebony and pau ferro all respond well to linseed oil.
