I'm Indian, but if they claim Indian food smells, you could ask them to write down in the contract that you will bear the damage caused by the smell sticking onto the surfaces it interacts with, either by replacing/repairing what's damaged or paying for the replacements/repairs which could be included in the caution deposit. Another reassurance would be to write in the contract that the house owner can legally enter the property to check/inspect for any damages to re-assure and charge for any damages.

The problem with these clauses is that people can exploit you.
