How should a commercial oven be cleaned daily?

Please verify the following points and require itemized written supplier responses:（commercial oven oven-cleaning） After cooling, remove trays, clear residue and grease, use suitable oven cleaner and avoid spraying controls directly. Daily cleaning is safer than allowing grease buildup and helps reduce odors and fire risk. Define capacity, accuracy, materials and operating environment before requesting quotes on a uniform basis. Request specification sheets, test reports, certificates, maintenance manuals and spare-part lists. During acceptance, verify appearance, dimensions, functions, safety protection and packaging, and keep test records. Do not compare unit price alone; include customization, freight, spare parts, after-sales support and downtime risk. Keep written records of inquiries, confirmations, FAT, acceptance and warranty commitments.
