**The short answer**

A garage detailing bay needs three things a garage does not usually have: water you can get to, somewhere for it to go, and light that hits paint at a low angle so swirls show. Sort those before anything else, then put every bottle, pad and towel on the wall so the floor around the car stays clear.

## Room around the car is the whole bay

A detailing bay is the space around the car, not the car. You need to walk all the way round it, open every door, kneel at the sills and swing a polisher at the rear quarter without hitting a shelf. In a modern single garage with a modern car that space does not exist, and no amount of kit creates it. The honest plan for most single garages is to wash outside on the drive, and to use the garage for drying, correction and protection with the car pulled forward and the door open.

What the garage can do is give you the walls. Every bottle, pad, towel and brush that is on the floor is in the way of your feet and your hose, and one kicked bucket of rinse water tells you that. The bay works when the floor around the car is empty and everything you reach for is on the wall at the height you use it. Set that up before anything else, because it is the only thing that gets you space back.


## Water in, water out

Water in is the easy half. An outside tap through the garage wall, a hose reel on a steel hook by the door, and the pressure washer on a shelf with its lance hung beside it. Water out is the half that stops people. Most garage slabs have no drain; the water goes wherever the slab falls, which is usually towards the door, and sometimes towards the back corner where it sits. Watch where a bucket of water goes on the bare slab before deciding whether washing inside is realistic.

If water will not leave on its own, a squeegee to the door and a wet vac for the corners are the tools, and you plan the wash for the drive anyway. A pressure washer indoors also fills the room with mist that settles on every surface and every tool, which is another argument for washing outside. Water and electricity in the same room is the serious point: any socket a washer or a polisher plugs into wants RCD protection, and an extension lead lying in a puddle is not a garage problem, it is a hospital one.

Interlocking floor tiles float over the slab, and water goes through the joints and sits underneath. That is fine for a wet car dripping dry; it is not fine for a floor that gets flooded weekly with nowhere for the water to go. If you wash on tiles, lift a section now and then and let the slab dry, or keep the tiled area to the working side of the bay and the washing on bare slab or the drive.


## Lighting for seeing swirls, not for seeing the room

Bright, even light from the ceiling is exactly the light that hides swirl marks. Swirls are fine scratches that show when a single point of light reflects off the paint at a low angle; diffuse light from everywhere reflects from everywhere and there is nothing to see. A garage lit like a showroom looks good and tells you nothing, which is why a car that looked perfect indoors looks like a spider's web in the supermarket car park.

So you want two kinds of light. General light overhead to work by, and something you can move: a handheld torch or a small lamp on a stand you can hold low to the panel and sweep across it. Inspect with the general light off. Wall-mounted light at bonnet height on the side of the bay helps with doors and wings, and a light you can point at the roof from below shows what the ceiling light hides. The colour and brightness figures belong in a lighting guide; the angle is what matters here.


## Bottles, pads and towels off the floor

Detailing kit is small, plentiful and mostly liquid, and it ends up on the floor in a row along the wall where it gets kicked, frozen and knocked over. A shallow four-tier steel shelf takes bottles at the front where the labels read, and shallow is the point: a deep shelf becomes two rows with a forgotten row behind. Pads and brushes go in tilt bins on a wall panel where a used pad cannot touch a clean one. Towels live in a closed tub, because a towel that has picked up a grain of grit off the floor is a towel that scratches.

A pair of gridwall panels takes the odd-shaped things — buckets on hooks, a basket for the wheel brushes, the drying towel over a bar — and can be rearranged as the collection grows, which it will. Whatever you hang, hang it on the side of the bay away from where the car door swings, and above the height a wet car door would meet it, because a door edge against a hook is the one scratch you did not need to inspect for.

| Item | Where it lives | Why not the floor |
| --- | --- | --- |
| Bottles and sprays | Shallow shelf at chest height | Kicked over, and they freeze on the slab in winter |
| Pads and brushes | Tilt bins on a wall panel | A used pad on the floor picks up grit and contaminates the rest |
| Microfibre towels | A closed tub on a shelf | One grain of grit in a towel scratches paint |
| Hose and lance | Steel hooks by the tap | A hose on the floor is a trip and a kink |
| Buckets | Hung on hooks or stacked on gridwall | They hold the whole floor otherwise |


## Cold, damp and chemicals

An unheated garage in winter freezes what is on the floor first, because the slab is the coldest thing in the room. Some water-based products separate or spoil once frozen, and the label will usually say. Shelving off the slab and away from the outside wall is most of the answer; bringing the few frost-sensitive ones indoors for the coldest weeks is the rest, and it is less effort than replacing them in March.

Washing or drying a car inside puts a great deal of water into the air, and warm moist air condenses on the coldest surfaces it finds: the tools, the door, the car you just dried. Leave the door open while the car dries when you can, and get air moving afterwards. Solvent-based products and the dust from polishing want ventilation too. A bay that smells of last week's tar remover on Monday morning is one that was shut up wet.

## Common questions

**Can I wash my car inside the garage?**

Only if you have watched where the water goes. Most garage slabs have no drain, and the water runs to wherever the floor falls, sometimes a back corner. A pressure washer indoors also mists everything in the room. The usual plan is to wash on the drive and bring the car in for drying, correction and protection.

**What lighting shows swirl marks best?**

A single point of light held low and swept across the panel, with the general lights off. Swirls only show when light reflects off them at a low angle, and bright even ceiling light hides them completely. Use overhead light to work by and a handheld torch or a small movable lamp to inspect with.

**Where should I store detailing products in a cold garage?**

Off the slab and away from the outside wall, on a shallow shelf where the labels face out. The floor is the coldest place in the garage and the first to freeze what stands on it. Check labels for products that spoil when frozen and bring those few indoors for the coldest weeks.

**Are interlocking floor tiles suitable for a detailing garage?**

For the working side of the bay, yes; they lift a car off a dusty slab and they can be taken up again. Water goes through the joints and sits underneath, so a floor that is flooded weekly needs the tiles lifted now and then to dry, or the washing kept to bare slab or the drive.
