In the general meaning of cleaning, 'putzen' is often combined with rooms or areas in the house. Typical examples are: 'die Wohnung putzen' (to clean the apartment), 'das Bad putzen' (to clean the bathroom), 'die Küche putzen' (to clean the kitchen).

We should clean the whole house today.
When 'putzen' is used in the context of food, it means 'vorbereiten' (to prepare). You can recognize this meaning from objects such as vegetables, salad, or mushrooms.

to do / make
'machen' and 'putzen' can both mean that something becomes clean or tidy. Here, 'machen' is very general and often needs a suitable object or extra word, for example 'das Zimmer machen' (to do / clean the room) or 'sauber machen' (to clean). 'putzen' is more precise: you remove dirt, often by wiping, scrubbing, or sweeping. Learners may confuse the words because in everyday life you sometimes hear both in connection with housework. When dirt is the focus, 'putzen' is more natural. When you mean tidiness or cleanliness in general, 'machen' can fit.

Vor dem Besuch mache ich noch schnell das Bad sauber.
