Maintenance points (1) If the surface is stained by burning, it can be lightly ground with fine sandpaper, then rubbed with the sealant and the polish to restore the original condition. (2) For daily cleaning, first wipe it with a common mop like a cement floor, then dry the water with a dry cloth. (3) Generally, the polish is applied once every 3 to 6 months (once). Disadvantage Dirty. This is caused by the stray holes left by the polished tiles during polishing. These pores will taint dirt, and even some tea will smudge on the polished tiles. Later, some good quality polished tiles were added with an anti-fouling layer at the factory, but this anti-fouling layer had the effect of losing the polished bricks.
