Stay away from oil-based (aka "solvent" based) finishes. Things that have high solvent content (ie. high VOC content) will turn yellow before you can blink. That also includes oil-MODIFIED! That means you have to step out of the "cheap" off-the-shelf option and into the professional grade water based products.

Here's a hint: Minwax 550 = VOC content of 550g/L (OMG!). And it gets better: Minwax 650 = VOC content 650g/L. Needless to say these are illegal in 11 states!

You want a water based product that guarantees a "clear coat" and "will not amber" (that's the name for turning yellow).

White washing is tough to achieve. White Oak has it's own issue with TANNIN PULL. That's when the YELLOW TANNINS in white oak rise to the surface and turn a very subtle yellow (nothing as bad as minwax ORANGE).

Tannin pull is made WORSE by "water based" clear coats. That means you need to use a sealant on white oak when you work with water based finishes. Fun isn't it?

Now imagine trying a white wash without knowing any of that? Right. There are literally hundreds (if not THOUSANDS) of refinishers who don't know what you just learned. So pick your battles and your FLOOR PROFESSIONALS very carefully.
