Furniture polish build up

[kissmelittleass]

On my dining table has made it look dull and there are matt dull patches everywhere!! Read a tip on using tea but has made it look worse!!
It's mango wood so quite dark any advice to remove build up appreciated

This seems to suggest you shouldn’t use polish? Did it say anything about care instructions when you bought it?

“Cleaning
Try not to use a damp cloth to wipe the surface of your mango wood, as this may cause discolouration. To clean effectively, use a dry cloth without any polish or solution to prevent the risk of removing the natural wax. However, using a tiny bit of beeswax would be ideal to clean the surface properly, as well as adding to the woods protective coating.
By opting for these easy to follow care instructions, you can keep your furniture new and add life to it. Wood furniture can last for generations if proper care is taken of it.”

Not sure if this would make it worse or not tbh
