Lacquer asks almost nothing — which is exactly why it gets abused with whatever spray is under the sink. Here is the whole regimen.
The only routine you need
Warm water, a drop of dish soap, a well-wrung microfibre; wipe with the panel, then once dry with a second cloth. Weekly for handles zones, monthly whole-kitchen. That is genuinely all a sealed lacquer surface requires.
The blacklist
No magic erasers (they are micro-abrasives), no citrus or ammonia sprays, no bleach, no furniture polish that leaves silicone films. One enthusiastic scrub with an abrasive pad dulls a matte finish permanently.
Grease zones
Above the hob, let a damp soapy cloth sit against the film for thirty seconds to soften grease rather than scrubbing. Finish with the dry cloth to avoid streaks on satin and gloss.
