* Type of painting: oil oxidizes more easily than acrylic. For this reason, acrylics more outside coating.
* Quality: It is true that you get what you pay for, cheaper paint will oxidize and break down faster than high-quality paint.

* Determine the degree of whitening by rubbing a part of the dust on the surface in order to see how much the residue has been removed.
Mild whitening can be resolved by brushing, while moderate or severe calcification may require pressure washing or sand blasting.
* When the surface is dry, make sure the color is still in good condition. If so, do your work, if not, you need to vent to the surface to improve appearance.
