I have an Oak Dining suite which has gone very yellow. It catches the sun early morning which I'm guessing has caused the problem. Is there any way to lighten or whiten it without sanding the table and six chairs (with lots of spindles). I don't know what varnish/coating is on the timber. I love the whitewashed look but don't want to go to all that trouble for it to go yellow again. Any suggestions?

Hello @davalli
I'm afraid sanding is a necessary step when painting or coating timber furniture. Painting, coating or sealing over old paint or sealers is not recommended as the results will often be unfavourable. The paint or sealer will flake, crack or come up patchy instead of having a smooth uniform finish.
To expedite the sanding process, I highly recommend investing in an electric sander, cordless or corded the choice is up to you. The best part about the electric sander is that they come with a paper sanding set already included. It's often more than enough to do a single timber furniture such as a table or chair.
A clear satin or matt finish will help reduce the glare coming from your window. I propose using a water-based sealer rather than oil-based. Oil-based sealers tend to yellow with age due to its composition. In regards to putting a white finish on the table, I recommend having a look at Feast Watson 1L Satin Liming White Stain And Varnish.
A technique you can try is to sand the top surface of the table only leaving everything else as is. Cover the sides of the table with masking tape so that it will not get accidentally sanded and you know where to stop. Once sanded and clean you can then apply the Liming White to the top surface only.
Another option is to use Sheer Curtains to diffuse and lessen the glare of the sun onto the table.
If you have any other questions we can help with, please let us know.

Hi @davalli, @EricL , @inspiredbycoast are right , the only way is the sand and recoat the table, also try to reduce the sunlight hitting the furniture, it’s the UV rays that is making it go yellow. If you don’t like sanding try this product ESP surface prep, it won’t hit rid of the yellowing, you can use this only if you want to paint over the table in a different colour

I have used this product many times over varnished doors, colourbond, and upcycled furniture’s
The tops were sanded and decorated, the sides and drawers were prepared using the ESP product
