Cars are getting taller. The explosion of SUVs and crossovers means that only the tallest drivers ever see their roof. And while the benefits of the extra space and a commanding driving position are clear, the obvious drawback with a taller car is cleaning its roof — especially if you aren’t tall enough to play for the Harlem Globetrotters.

So whether you own an SUV or are simply on the shorter side, we’ve compiled the best methods to reach those difficult areas without compromising the final results or risking damage to your paintwork. Follow these steps to ensure a thorough and safe cleaning of your car’s roof.

What you’ll need:

  • Step ladder or platform
  • Pressure washer or hose
  • Microfibre wash mitt
  • Car shampoo
  • Bucket filled with water
  • Microfibre cloth/ drying cloths

1. Get yourself a platform

Your best bet for reaching the uppermost parts of your car is to buy a good quality platform. Not only will this make sure you get full coverage when shampooing your roof and help minimise wasted products, but it’s the safest way to gain some extra height.

Make sure it has non-slip feet as it needs to remain stable even when the ground is wet. Also think of the logistics, aluminium is lighter to carry but can cost more than a steel example. A carry handle will also be useful but is not a deal-breaker. Finally, think about storing it when not in use, if you’re pushed for space look for a shorter platform that’ll take up less room.

The platform will also come in handy around the home for DIY as it is effectively a more stable step ladder. It’s perfect for redecorating, checking ceiling-mounted alarms and even changing lightbulbs. And while might seem expensive to buy a platform for cleaning, it’s a good investment and is a lot safer than using a stool or unturned bucket.

A little tip if you’re worried about knocking the platform and potentially scratching your paintwork is to wrap a cloth around the corners. That being said, most quality platforms will have plastic edges that offer protection and shouldn’t move if you stand centrally and balance your weight properly.

2. Rinse the roof

Now you’re towering above your car it’s time to clean it. Start by using a pressure washer with a suitable nozzle to thoroughly rinse the roof, removing loose dirt and debris. If you don’t have a pressure washer, a hose with a spray nozzle will also work effectively.

3. Prepare your bucket with soapy water

There are no specific cleaning products you’ll need for your roof, car shampoo will be enough in most instances. Fill a bucket with water and add the recommended amount of car wash soap. Mix until sudsy.

However, at Parkers we would recommend using at least two buckets: one for washing and one for rinsing. If you want to be extra cautious, opting for a grit guard in the bottom of the bucket will prevent any further dirt from being collected. Whilst this is not a necessity it will make the cleaning process a lot easier.

If you have a glass sunroof you can introduce a glass cleaner if you want, and remember to close it before you start cleaning your car.

4. Begin washing the roof with a microfibre brush

Don’t be tempted to use one of those long caravan cleaning brushes as the tough bristles will leave nasty scratches. You’re far better off buying an extendable microfibre brush that’ll wash your car effectively without damaging the paint.

Dip you microfibre brush into the soapy water, using gentle, circular motions, clean the roof starting from the centre and working your way outwards. Make sure you rinse the brush frequently to avoid dragging dirt across the paint.

If you don’t have a extendable microfibre brush or have long arms and a lower car, you may be able to get away with a wash pad instead. A microfibre wash pad is advantageous over a wash mitt when it comes to the roof as it allows you a little more reach.

It’s also worth remembering not to lean over the car too much. Not only can the zippers and buckles on your clothing cause scratches, but more importantly you risk losing your balance, falling off the platform and hurting yourself. If you’re concerned about scratches, an old apron or even a bin bag will provide some extra protection.

5. Dry the roof

Finally, use a large drying towel or microfiber towel to gently dry the roof. A larger towel is more effective at absorbing liquids and won’t damage the paintwork, and it can even be used to clean a glass sunroof safely.

FAQs

What do you use to wash a soft top car roof?

Unlike a metal car body, soft top roofs can be attacked by dirt, mould and mildew easily without proper care and attention. You will need to invest in a soft top cleaner, that is specifically designed to remove dirt, grime and even bird droppings from your convertibles roof.

Apply the soft top cleaner according to the product’s instructions. It’s important to use the correct cleaner for your roof’s material; fabric, vinyl, and mohair convertible roofs each require specific products for optimal care.

Rinse it off with plenty of water until it runs clear. However, we wouldn’t recommend using a pressure washer to rinse off any excess product on your roof, as high-pressure water can damage the fabric, especially if it has small holes or tears.

What is the best way to clean your headliner?

You’ll first want to remove any debris or loose dirt stuck on the headliner by wiping it down with a microfibre cloth, try not to rub the dirt particulates into the fabric of the headliner. Next, you’ll want to wipe the stained area with a microfibre cloth, make sure you only saturate a small area of the cloth with your upholstery cleaning spray, or just spray directly onto the affected area.

Then gently wipe the stain with the damp part of the towel. Last but not least wipe away any excess moisture with a dry microfibre cloth.
