Lo spazzolino di pulizia toglie il residuo di caffè.

Because spazzolino begins with sp-, and masculine singular nouns starting with s + consonant usually take lo in the singular definite article.

So:

• lo spazzolino
• lo studente
• lo specchio

But in the plural, it becomes:

• gli spazzolini

This is a sound-based rule in Italian, not a meaning-based one.

Spazzolino is the diminutive form of spazzola.

• spazzola = brush
• spazzolino = little brush / small brush

The ending -ino often makes a noun sound smaller or more specific. In many contexts, spazzolino can mean:

• toothbrush
• small cleaning brush
• little brush attachment

In this sentence, it refers to a small brush used for cleaning.

Di pulizia means for cleaning or used for cleaning.

So lo spazzolino di pulizia is literally:

• the cleaning brush
• or more literally, the little brush of cleaning

Italian often uses di + noun where English might prefer:

• an adjective, or
• for + -ing

Other examples:

• prodotti di bellezza = beauty products
• occhiali da sole = sunglasses
• macchina da caffè = coffee machine

So here di pulizia describes the purpose of the brush.

Togliere is the infinitive, meaning to remove or to take away.

In the sentence, the verb has to agree with the subject:

• Lo spazzolino = the brush
• that is third person singular

So the present tense form is:

• io tolgo = I remove
• tu togli = you remove
• lui/lei toglie = he/she/it removes

That is why the sentence uses toglie:

• Lo spazzolino di pulizia toglie...
• The cleaning brush removes...

Il residuo is the direct object, so it gets its own definite article:

• il residuo = the residue

Then di caffè means of coffee. In Italian, when one noun modifies another like this, the second noun often appears without an article.

So:

• il residuo di caffè = the coffee residue / the residue of coffee

This is very common:

• una tazza di tè = a cup of tea
• il sapore di limone = the taste of lemon
• macchie di vino = wine stains

Yes, residuo is a normal word, especially in technical, cleaning, cooking, or maintenance contexts.

It means:

• residue
• leftover material
• deposit

In this sentence, il residuo di caffè suggests bits, buildup, or traces of coffee left behind after use.

It sounds a little more specific and technical than something very general like sporco (dirt).

Yes. That would mean coffee residues or coffee grounds/traces, depending on context.

Compare:

• toglie il residuo di caffè = removes the coffee residue
• toglie i residui di caffè = removes the coffee residues

The singular can sound like residue viewed as one mass or buildup. The plural can suggest multiple bits or deposits. Both can be natural depending on context.

This is the normal Italian order:

subject + verb + object

• Lo spazzolino di pulizia = subject
• toglie = verb
• il residuo di caffè = object

So the sentence is very straightforward and neutral.

You can change the order in some contexts, but it would usually sound marked or literary, for example:

• Il residuo di caffè lo toglie lo spazzolino di pulizia.

That structure adds emphasis and is not the plain default form.

Togliere is very natural here. It means to remove, to take off, or to take away.

Other possible verbs might be:

• rimuovere = to remove
  More formal or technical.
• eliminare = to eliminate/remove
  Slightly more formal.
• pulire via is not usually the best standard option here.

So:

• Lo spazzolino di pulizia toglie il residuo di caffè sounds natural and idiomatic.

A rough pronunciation guide:

• spazzolino ≈ spaht-tsee-LEE-noh
• pulizia ≈ poo-lee-TSEE-ah
• toglie ≈ TOH-lyeh

A few useful points:

• zz in spazzolino is pronounced like ts or tts
• gli in toglie is a special Italian sound, somewhat like ly in English, but softer and more fused
• Stress matters:
  • spazzoLIno
  • puliZIa
  • TOglie

Grammatically, yes, because spazzolino often means toothbrush. But in this sentence, di pulizia and residuo di caffè make the meaning clear: it is a small cleaning brush, not an ordinary toothbrush for teeth.

So context decides the exact translation:

• spazzolino by itself can be ambiguous
• spazzolino di pulizia is much clearer

Because caffè is stressed on the last syllable, and in Italian words stressed on the final syllable often take a written accent.

So:

• caffè
• città
• perché

The accent here is not optional. It is part of the correct spelling.

Yes, especially in instructions, product descriptions, appliance manuals, or cleaning contexts.

It sounds a bit more functional than conversational, which is normal for this kind of sentence. For example, you might see it in:

• a coffee machine manual
• cleaning instructions
• product packaging

In casual speech, someone might also say something like:

• Questo spazzolino toglie il residuo di caffè.
• Lo spazzolino serve a togliere il residuo di caffè.

But the original sentence is perfectly natural.
