Question 1

Which technique best removes deeply embedded pet hair from automotive carpet?

Accepted Answer

Rubber glove dragged across carpet to create static lift

Answer

A rubber glove creates friction and static electricity that causes pet hair to clump and lift from carpet fibers, making it far easier to vacuum away.

Question 2

A technician notices white chalky residue on dark plastic trim after applying an interior dressing. What caused this?

Accepted Answer

Too much product was applied and not fully buffed in

Answer

White residue on trim after dressing indicates excess product that dried without being buffed in — always apply interior dressings sparingly and buff thoroughly.

Question 3

What type of brush is most appropriate for agitating a vehicle headliner during cleaning?

Accepted Answer

Horse hair upholstery brush with ultra-soft bristles

Answer

Headliners are made of delicate fabric bonded to foam backing; ultra-soft horsehair brushes agitate gently without damaging fibers or loosening the adhesive bond.

Question 4

When detailing door jambs and sills, what is the correct sequence?

Accepted Answer

Clean → dry → apply protectant

Answer

Proper sequence is clean, dry, then protect — applying protectant to a dirty or wet surface traps contaminants and prevents proper adhesion.

Question 5

Which interior surface is most prone to harboring odor-causing bacteria and should receive enzymatic treatment?

Accepted Answer

Carpet and fabric seat upholstery

Answer

Carpet and fabric upholstery trap organic matter — spills, pet dander, and body oils — creating an ideal environment for bacteria that produce persistent odors.
