To clean car door shuts, spray a diluted all purpose cleaner such as AutoBead All Purpose Cleaner, work it round the hinges and seals with a soft brush, wipe it away with a damp microfibre and finish with AutoBead Quick Detailer. It takes about ten minutes a door. Both all purpose cleaners we use, AutoBead and Better Car Care Versatility, are in our all purpose cleaners range.
What are door shuts and why do they get so dirty?
Door shuts, or door jambs, are the painted frames and edges you only see with the door open: the sill step, the hinge area, the latch and the rubber seals. Water running off the roof carries road dirt into them, hinge grease collects grit, and in winter salt and slush get trodden in every time someone climbs in.
A normal wash rarely reaches them, so the dirt sits there for months. That is why clean door shuts are one of the first things a buyer or a valeter notices, and why they are worth ten minutes on every deep clean.
What do you need to clean door shuts?
A diluted cleaner, a soft brush, something thin for the gaps and a few clean microfibre towels.
A highly concentrated APC that lists door shuts among its jobs. On the outside of the car, dilute it 5:1 for heavy soiling, 10:1 for medium and up to 30:1 for light dirt. Used neat it may strip wax and sealant, so dilute it for shuts.
A concentrated APC for door shuts, engine bays, plastics and trim that buffs off with a natural low sheen and no residue. Agitate it with a detailing brush and wipe it with a clean, soft microfibre.
Better Detailing Synthetic Short Brush
A 17cm metal-free brush with soft synthetic bristles for trim gaps, badges and tight areas, and safe with mild APCs.
TDHQ Microfibre Detailing Sticks
Long, slim sticks with an ultra-soft microfibre head for seams and gaps where a brush or towel will not reach.
How do you clean door shuts step by step?
Work one door at a time, top to bottom, with the door fully open and the car in the shade.
- Dust out first: vacuum or brush loose grit out of the sill and the bottom of the door before anything wet goes on, so you are not scrubbing grit into the paint.
- Mix the cleaner: dilute the APC in a spray bottle, weaker for light dirt and stronger only for heavy grime.
- Spray onto the brush, not the electrics: mist the painted shut and the brush rather than spraying into the latch, the wiring boot or the speaker area.
- Agitate gently: work the brush round the hinges, the latch and along the seal edges, then use a detailing stick in the tightest seams.
- Wipe it away: take the dirt off with a damp microfibre towel, turning it often, then dry the whole shut with a second towel.
- Finish the paint: mist a quick detailer onto a clean microfibre and wipe the painted areas for gloss and a little protection.
- Close it dry: make sure the seals and the bottom of the door are dry before you shut it.
Should you pressure wash door shuts?
We would not aim a pressure washer straight into an open door shut. The jet can force water past the seals into the cabin, into wiring and speaker areas, and it can blast grease out of the hinges. A low-pressure rinse with the door closed during the main wash is fine. The proper clean is done by hand with the door open.
How do you clean and look after the rubber door seals?
Wipe them with the same diluted cleaner on a microfibre, never a stiff brush, then dry them. Clean, dry seals stay supple and seal better, and in winter dry seals are far less likely to freeze the door shut overnight.
A cream dressing for rubber, plastic trim and tyre sidewalls that dries to a satin, dry-to-the-touch finish and helps repel water and grime. Apply it thinly with a foam applicator and reapply it monthly.
How do you protect door shuts after cleaning?
Give the painted areas the same kind of protection as the rest of the car, applied to clean, dry paint. A quick detailer is the easy option every time you clean them, and a spray sealant lasts longer on shuts that get a lot of winter dirt.
A polymer quick detailer that removes dust and fingerprints and adds gloss and clarity. Mist it onto a short pile microfibre, work in straight lines and buff off.
Silicone polymers and silica resins rated for 9 months on paintwork and wheels. Spray it onto a microfibre applicator, let it bond for 1 minute and buff off with a short pile microfibre.
Common questions
Should you clean door shuts before or after washing the car?
After the exterior wash, while you still have clean water and towels to hand. If the car is very dirty, do the shuts first so dirty water from them does not run onto clean paint.
How often should you clean door shuts?
Give them a quick wipe whenever you wash the car and a proper clean every few months, more often through winter when salt gets trodden in.
Can you use an all purpose cleaner around the hinges?
Yes, diluted and wiped off. Clean the grime from around the hinge rather than trying to strip every trace of grease from the pivot itself.
Can you use the same towel on the shuts and the paint?
Keep separate towels for shuts. They pick up grease and grit that you do not want anywhere near the main paintwork.
For every job a diluted APC can do, see how to use AutoBead All Purpose Cleaner, and the correct order to detail a car shows where shuts fit in a full valet. Our routine for protecting your car in winter covers the rest of the car through the cold months.
