How to Keep Your Car Clean Between Details

Outside

The exterior habits that matter

Bird droppings and sap off within a day. The highest-value habit on this list by a wide margin. Both are acidic, both etch clear coat, and both are a two-minute job when fresh and a correction quote when not. See the removal guide.
No automatic tunnel washes. The brushes carry grit from every car before yours. This is the single fastest way to undo paint work you have paid for.
Rinse after a week parked near the coast. Salt film holds moisture against the paint. A hose-down is worth more than a full wash a fortnight later.
Do not park under the obvious tree. The space that is always free is free for a reason.
Dry it if you wash it. Air-drying in hard water is how you get water spots. If you are not going to dry it, a rinse is better than a half-wash.
Do not wash in direct sun. Water evaporates before you can dry it and every droplet dries in place.

Inside

The interior habits that matter

Blot spills immediately, never rub. Rubbing spreads it sideways and drives it into the foam. The stain guide has the full method.
Take rubbish out when you get out. Obvious, and it is the difference between a car that needs a vacuum and one that needs a rescue.
Dry floor mats outside the car after wet days. Rubber mats trap water underneath and hold it against the carpet for days. This is most of the musty-car problem in San Francisco.
Vacuum the footwells every couple of weeks if you can. Grit in carpet is an abrasive that cuts the fibre every time somebody puts a foot down.
A hair blade in the door pocket if a dog rides with you. Two minutes a week stops hair getting worked down into the weave, which is the part that costs money to reverse.
Crack a window on hot days. Heat accelerates everything biological in the car and cooks the dashboard.
A sunshade. Genuinely the best-value car care item there is. It protects the dash, the wheel and the seats from the thing that actually ages them.

Kit

What is actually worth keeping in the car

A short list. Everything here earns its space in the boot.

Two clean microfibres

One for glass, one for everything else. Wash them separately from household laundry and never with fabric softener, which ruins their absorbency.

A quick-detailer spray

For lifting a fresh bird dropping or a fingerprint on the paint. Not a substitute for washing a dirty car — that is how you scratch it.

A rubber pet hair blade

If a dog rides with you. Costs almost nothing and prevents the add-on you would otherwise be buying.

A small bin or bag

Unglamorous and effective. Most interior mess is rubbish that had nowhere to go.

A folding sunshade

The single most effective interior protection product available, and it is not a product at all.

A spare bag for wet things

Wet gear straight onto carpet is how a car gets a smell it keeps.

Protection

The thing that makes all of this easier

Habits are effort, and effort is the thing people run out of. The way to reduce the effort required is to keep a protective layer on the paint.

It works because contamination lands on the protection rather than on bare clear coat. Bird droppings have something to work on other than your paint. Salt film sits on a surface it cannot bond to. Dirt releases with far less contact during a wash, which means fewer new swirl marks.

The levels are: the protection included in every Exterior Wash & Protection, renewed at each visit; a 12-month or 2-year sealant; or a Gtechniq ceramic coating rated 2 to 5 years. The comparison guide covers what each one actually buys.

The honest note about this city: salt air and fog wear protection down faster here than in a dry inland climate. That is an argument for keeping something on the paint rather than an argument against, but it does mean an annual top-up matters more here than the marketing suggests.

Or put it on a rhythm

The realistic version for most people in San Francisco, where nobody has a hose: an exterior wash every two to three weeks at your address, and a full detail two or three times a year.

You do not have to be there, and you do not have to move the car. That is the whole reason the friction disappears.

Questions

Questions we get asked

How do I make a detail last longer?

Get bird droppings and sap off within a day, avoid automatic tunnel washes, and keep a protective layer on the paint. Those three account for most of it.

Is it worth washing my car myself between details?

If you do it properly, yes. Two buckets, wheels first, straight lines, dried by hand. Done badly it does more harm than leaving it dirty.

What should I never use on my car?

Household washing-up liquid, all-purpose cleaner on leather, household solvents on paint, and automatic tunnel washes. Each of those causes damage that costs more to reverse than the shortcut saved.

How often should I vacuum?

Every couple of weeks if you can. Grit in carpet is abrasive and cuts the fibre every time somebody puts a foot down, so removing it is preventative rather than cosmetic.

Does a sunshade really matter?

More than any interior product. UV through glass is what cracks dashboards and dries leather, and a sunshade is the only thing that meaningfully blocks it.
