Training a new car washer in one week

"Just watch Kwesi and do what he does." That is the training plan at most washes, and it works about as well as you would expect. The new boy copies Kwesi's good habits and his bad ones, learns nothing about why the degreaser must not touch the paint, and scratches a customer's bonnet in his second week with a mitt he dropped on the floor and did not rinse.

Proper car wash training does not need a classroom. It needs one week, one patient senior washer, and a plan that puts the expensive mistakes first. The week below assumes a normal wash with a pressure washer, buckets, a foam cannon and a vacuum, but it works with less.

Pay the trainee for the week. If you want a wider view of what to look for before the week even starts, see hiring car washers in Ghana who stay.

Day one: safety, water and the things that hurt

Start with what can injure him or the customer's car. A pressure washer at close range can cut skin and strip paint. Show him the safe distance, the fan tip, and the rule that the lance never points at a person, a tyre valve or a cracked windscreen. Show him where the generator sits, that petrol is never poured while it runs, and how to switch off the pump if a hose bursts.

Then chemicals. Every bottle gets named: shampoo, degreaser, tyre shine, glass cleaner, and the acid wheel cleaner if you use one. He learns which ones go on paint and which never do, that dilution ratios are written on the drum for a reason, and that undiluted degreaser on a plastic bumper leaves a white stain you cannot remove. Gloves for the strong ones.

Day two: the order of washing

The second day is about sequence, because most of the damage to paint comes from doing things in the wrong order. Rinse first, always, from the roof down, to lift the Harmattan dust and grit before anything touches the panel. Then wheels and tyres, because the dirtiest part should not splash onto a clean door later. Then foam or shampoo, roof down again. Then rinse, then dry.

Teach the two-bucket method and insist on it. One bucket of shampoo water, one bucket of clean rinse water, and the mitt goes into the rinse bucket before it goes back into the shampoo. A grit guard at the bottom of each bucket helps if you have them. A mitt that has fallen on the ground is rinsed thoroughly or swapped, never used as it is.

Day three: drying and the parts people notice

Customers do not inspect the roof. They look at the mirrors, the door handles, the windscreen, the rims, and the water streaks on the boot. Day three is about those.

Drying towels are used in a set order: glass first with a dedicated towel, then paint, then door jambs and sills, and a separate towel for rims and tyres that never touches the paint. Towels that fall on the ground go to the laundry pile, not back on the car. A chamois or microfibre that is wrung out too hard leaves streaks; show him how damp it should be.

Day four: interiors and other people's property

Interiors are where trust is won or lost, so this day begins with manners rather than vacuums. Before he opens a door he asks the customer whether there is anything they want to remove. He never opens the glove box, the centre console or a bag unless asked to. Money, phones, Bibles and sunglasses are left exactly where they are, and anything he finds on the floor is placed on the dashboard in view, not in his pocket.

Then the work: seats back, mats out and washed separately, vacuum from the top down, crevices with the narrow tool, dashboard wiped with a damp cloth and a mild cleaner, never the tyre shine that some washers use because it looks glossy for a day and attracts dust for a month. Mats back only when dry.

Day five: customers, keys and the end of the day

Keys are the simplest thing to lose and the hardest to explain. Teach one rule: keys go to one place, a labelled board or a box with the cashier, with a tag matching the car, and nobody drives a customer's car anywhere except from the queue to the bay and back. If the customer wants the car moved to the shade, the customer moves it.

Then customer manners, which are mostly listening. Greet, ask what they want, repeat it back, say roughly how long it will take, and go and find the manager if the customer wants something off the price list. If a customer asks for the mirrors to be redone, redo them without a face. If a customer says the car was scratched, do not argue; call the manager and let the walk-around record speak, as described in keeping customers happy at the wash.

Days six and seven: speed, the Saturday test and signing off

By the weekend he should be doing a saloon full wash alone in a reasonable time, with the senior washer only checking the result. Saturday is the test. Put him on real cars in a real queue, let him feel the pressure, and watch whether the two-bucket habit survives when there are six cars waiting. If it does not, that is the lesson for the following week, not a reason to shout.

On Sunday evening or Monday morning, sit with him for ten minutes, name two things to fix, and write the date he completed training in your notebook. Your next step is to choose the senior washer who will run this week for the next trainee, and tell him he is now responsible for it.
