toothpaste
White paint on the surface of wooden furniture will turn yellow after a long time. You can wipe it with a rag and toothpaste. Be careful not to push too hard.
Egg yolk smear
Stir the two egg yolks evenly, apply them to the yellow place with a soft brush, dry them and wipe them carefully with a soft cloth.
Tea+corn flour
Apply the remaining tea leaves to the yellow part, then spray a small amount of corn flour to wipe it, and finally wipe off the corn flour. Corn flour can suck away all the stolen goods adsorbed on the furniture surface, making the paint surface smooth and bright.
