Hey everyone — running an Alto-Shaam combi oven in a professional kitchen and dealing with pretty heavy calcium/mineral buildup.

We’ve already tried:

• Light rinse cycles
• Basic descaling attempts
• Regular cleaning tablets

Still seeing residue, especially on the floor and around the fan area.

A few questions for anyone with real experience:

• Are you running a full descaling cycle regularly, or spot treating?
• What chemicals are you actually using that work (brand + dilution would help a lot)?
• Have you ever had buildup that required manual removal (scrubbing / acid soak)?
• Does this usually point to a water filtration issue upstream?
• Any tricks for clearing buildup around the fan / steam system without damaging anything?

Trying to avoid damaging components but also need to get this thing properly clean — right now it feels like there’s still scale even after cleaning cycles.

Appreciate any real kitchen-tested advice 🙏
