I don’t think you are supposed to use anything other than a soft clean cloth on antiques - anything else will take away the ‘patina’ that antique collectors are supposed to covet.
We use a product on our modern furniture that is a combination of orange oil and beeswax. It does an excellent job. My husband gets it at woodworkers’ conventions, but I’m sure it’s available elsewhere.
I like “Liquid Gold” for our wood furniture- I have some older stuff that I’m not sure qualifies as “antique”, but it does a nice job and doesn’t smell like plastic lemons.
Well, the answer depends on whether you want your modern furniture to be an antique someday. If these are pieces you plan to hand down through the family, I suggest you start treating them like antiques now.
I strongly recommend you don’t use *any * polishes when dusting. Even the ones which claim to leave no residue leave a trace of themselves behind.
We used to use Endust, which is supposed be residue-free. As an added precaution against getting too much on the surface, we were instructed to lightly spray the rag, not the item to be dusted, and to never use so much polish as to make the rag damp with it. (Just a few “squirts” to do an entire room.)
In one of our rooms is a table with a heavy item on top of it. There’s no way to move the item, so to dust, you have to reach behind it, but you can never quite get completely around. The other day, my curator moved the heavy item, and was aghast at what he saw. Even with all of our precautions, you could clearly see the the difference between the “polished” area and the place we couldn’t reach. It was amazing that such a residue had built up in just a few years time.
My grandparents, who did 40+ years in the antique business, would always use genuine lemon oil (not Pledge) on wood furniture. Smells like real llemons, which is a lovely smell!
