Polishing is a gameplay element introduced in the Happy Home Paradise DLC for Animal Crossing: New Horizons that gives players the opportunity to add effects to furniture items. While inside their own home, or while customizing another villager's interior or inside Photopia, the player can press the L button to switch to polishing mode. While in polishing mode, the player's outfit will change accordingly. The outfit that the player dons cannot be purchased separately.
The polishing outfit used by the player. These pieces of clothing are only worn when polishing and cannot be obtained as items.
Once the player is in polishing mode, the player can select a furniture item to polish by pressing the A button. The player can hold the A button to boost the polishing effect dramatically. If the player wants to delete the current polishing, they can simple press A on the furniture item to wipe it off. The player can also select another polishing effect to override the current effect on a furniture item. Custom designs can also be used in tandem with the polishing effect.
Polishing can be learned from Niko while in the process of completing the fourth house for Paradise Planning. Initially, only one polishing effect, Sparkleblast, is obtained, but after completing the twelfth house, the player will unlock the remaining 13 polishing effects and have the ability to use custom designs with polishing.
