I have some walnut wood furniture (dining table, coffee table) that doesn't have a permanent finish. I've treated it in the past with boiled linseed oil that's dissolved in turpentine, but I'm looking for alternatives. I don't like the turpentine, would it be possible to use oil without the presence of a solvent? The dining table has a very smooth finish so I'm sure it would be easy to treat with a thicker oil. The coffee table wood has a more open structure, so spreading the oil would be more of a problem. I'm also wondering about the type of oil, I have the idea that linseed oil leaves a smell. Would grape seed oil be a better non-fragrant alternative? Hopefully people have some experience here :) The furniture store only recommends their commercial product, I went to a paint/diy shop who supplied me the boiled linseed oil in turpentine as a maintenance product.
