Puliamo il manometro con il panno in microfibra.

Puliamo is the 1st person plural form of pulire, meaning to clean. Grammatically, it is the present tense form we clean / we are cleaning.

In context, though, the same form can also be used as an exhortation, so it may mean let’s clean. Italian often uses the same verb form for both ideas, and the situation tells you which meaning is intended.

Italian usually leaves out subject pronouns when they are not needed. The ending -iamo already tells you the subject is we.

So:

• Puliamo = we clean / let’s clean
• Noi puliamo = also possible, but noi is usually added only for emphasis or contrast

English normally needs we, but Italian often does not.

Manometro is a masculine singular noun, so the article is il.

A few useful points:

• il = the for many masculine singular nouns
• manometro ends in -o, which is often a sign that a noun is masculine singular
• the sentence uses the gauge, not a gauge, because it is talking about a specific one

Con means with, and il panno means the cloth. Together, con il panno means with the cloth.

Here con introduces the tool or instrument used to do the action:

• Puliamo il manometro = we clean the gauge
• con il panno in microfibra = using the microfiber cloth

Yes. Col is a contracted form of con il.

So these are both possible:

• con il panno
• col panno

In modern standard Italian, con il is often felt to be a little more neutral and common in many contexts, while col is also perfectly correct and natural.

Italian uses articles more often than English does. With concrete nouns like panno, it is very normal to say il panno when referring to a specific cloth that is understood in the situation.

English might say with a microfiber cloth or with the microfiber cloth, depending on context. Italian often prefers the article where English might be less explicit.

In microfibra means made of microfiber or simply microfiber.

Italian often uses in + material to describe what something is made of:

• un tavolo in legno = a wooden table
• una maglia in cotone = a cotton shirt
• un panno in microfibra = a microfiber cloth

So in microfibra is describing the material of the cloth.

Because microfibra here is being used as a material in a general sense, not as a specific item.

So Italian normally says:

• in microfibra
• not in la microfibra

This is similar to how English says made of wood, made of cotton, made of steel, without adding the.

Not exactly. It is a prepositional phrase that describes panno.

English often uses one noun directly in front of another noun:

• microfiber cloth

Italian usually does not build noun phrases that way. Instead, it often uses:

• noun + descriptive phrase

So:

• panno in microfibra literally works like cloth in microfiber, but naturally means microfiber cloth

That is the most neutral and straightforward word order in this sentence:

• Puliamo = verb
• il manometro = direct object
• con il panno in microfibra = phrase showing the instrument used

Italian word order is flexible, so you could move the last part for emphasis:

• Con il panno in microfibra, puliamo il manometro.

But the original version is the most natural basic order.

Yes. That is one of the things that can confuse English speakers.

Puliamo can mean:

• we clean / we are cleaning
• let’s clean

The context tells you which meaning is intended. For example:

• in an instruction manual or spoken instruction, it often means let’s clean
• in a description of a routine, it may mean we clean

So the form is the same, but the situation makes the meaning clear.
