TLDR
On your BAKERLUX SHOP.Pro unit, rust spots on the stainless steel cooking cabinet typically indicate high chloride content in the inflow water, exceeding UNOX specifications. To resolve this, assess your water quality and install a UNOX.Pure-RO system if necessary. Polish the affected steel surfaces with an appropriate paste to remove existing rust.
Technical Details
Repair Steps:
- Diagnose Water Quality:
- Obtain a detailed water analysis report for your facility’s inflow water. Pay close attention to the chloride (Cl-) levels.
- Refer to your UNOX BAKERLUX SHOP.Pro technical manual for the exact permissible chloride content specifications. Exceeding these levels is a primary cause of stainless steel corrosion.
- Install a UNOX.Pure-RO Water Treatment System:
- If the water quality, specifically chloride content, does not comply with UNOX specifications, immediate action is required.
- Install a genuine UNOX.Pure-RO reverse osmosis water treatment system. This system is specifically designed to reduce chlorides, hardness, and other impurities to protect your oven.
- Ensure the system is correctly installed by a qualified technician, following all manufacturer guidelines. Regularly maintain the UNOX.Pure-RO system by changing filters as recommended.
- Polish and Restore Stainless Steel Surfaces:
- For existing rust spots on the cooking cabinet’s stainless steel, use a commercial-grade stainless steel polish paste designed for kitchen equipment.
- Apply the paste according to the product’s instructions, typically using a soft cloth or pad. Work in the direction of the grain of the stainless steel.
- Rinse thoroughly to remove any polish residue and dry completely. Regular cleaning and drying after use will help prevent future spotting.
- Consider implementing a descaling and passivation routine as part of your preventive maintenance.
Common Questions:
Q: Why does high chloride content affect stainless steel in my oven?
A: Stainless steel forms a passive chromium oxide layer that protects against corrosion. High chloride concentrations can break down this passive layer, making the steel susceptible to pitting corrosion and rust formation.
Q: Is the UNOX.Pure-RO system mandatory for all installations?
A: The UNOX.Pure-RO system is mandatory if your local water supply does not meet the specified quality parameters, particularly regarding chloride content, as outlined in your oven’s technical manual. It’s a critical investment to protect your equipment and warranty.
Q: Can any stainless steel polish be used for my UNOX oven?
A: It is recommended to use commercial-grade stainless steel polish pastes specifically formulated for professional kitchen equipment. Avoid abrasive cleaners or harsh chemicals that can damage the surface or leave residues that could affect food safety.
