We have an old varnished/waxed oak floor.

We want to wipe it clean and apply some new wax. The floor is getting
to be
a bit grimy.

Will mineral spirits cause the varnish to discolor or break down?

Are there any good cleaning products (non-toxic, safe around babies)
that you can recommend.
I found something called Treewax Wood Cleaner but can't figure out
what's in it.
