How do you clean a car with a steam cleaner? A step-by-step guide

Cleaning your car can be a time-consuming job, but with the right equipment -such as a steam cleaner - you'll make the process far more efficient and effective. Want to know how to thoroughly clean your car seats, dashboard and car windows? Read on! In this article, we give you a detailed guide to cleaning your car perfectly.

What is a steam cleaner and how does it work?

A steam cleaner heats water under high pressure to create steam. This steam is then sprayed onto the surface through a nozzle to remove dirt and stains effectively. The steam is powerful enough to loosen even stubborn dirt without damaging the surface itself. That makes steam cleaners ideal for delicate surfaces such as fabric car upholstery, car mats and dashboards.

Benefits of steam cleaning your car

It gets properly clean The steam penetrates deep into surfaces and removes even hard-to-reach dirt.

Health benefits: There's no need for chemical cleaning products. So you don't have to use harsh products.
Eco-friendly: Steam cleaners don't use cleaning products. That makes them an eco-friendly choice.

Take the Techweise TS1 Steam Cleaner or the Techweise TS2 Performance Steam Cleaner, which both come with a range of attachments and are ideal for cleaning your car.

What you need to clean your car with a steam cleaner

Before you get started, it's handy to have the following to hand:

A steam cleaner with a range of attachments (for example, the Techweise TS2 Performance Steam Cleaner)
Microfibre cloths
A vacuum cleaner (optional, for pre-cleaning)
Water (filtered or distilled)

Step-by-step guide to cleaning your car with a steam cleaner

Step 1: Prepare your car
Start by removing large bits of dirt and dust. A vacuum cleaner or a dry microfibre cloth makes this easy. Focus mainly on the seats, floor mats and the corners of the car.

Step 2: Fill the steam cleaner with water
Fill your steam cleaner's tank with distilled water. Ideally, avoid tap water, as it contains minerals that can build up inside your steam cleaner. Switch the steam cleaner on and wait for it to heat up and start producing steam.

Step 3: Clean the upholstery and seats
Use a suitable attachment for fabric or leather upholstery. Steam penetrates deep into the fibres and loosens dirt. Move the steam cleaner slowly over the upholstery and make sure you don't leave any wet patches. On leather seats, apply the steam briefly to remove dirt, but don't use too much. That way, you won't damage the leather.

Step 4: Clean the floor mats and carpets
Use a dedicated (carpet) brush to clean the floor mats and carpets. A steam cleaner like the Techweise TS2 Performance Steam Cleaner is particularly effective at lifting stubborn dirt and stains from carpet. Hold the steam cleaner a few centimetres above the carpet so you don't leave too much moisture behind.

Step 5: Clean the dashboard and door handles
For the dashboard and other plastic surfaces, use a small nozzle. These surfaces tend to attract dust and dirt. Move the nozzle slowly over the dashboard, door handles and buttons.

Step 6: Clean the windows and mirrors
You can also clean windows and mirrors streak-free with a steam cleaner. Use a window nozzle (also known as a squeegee) to steam the windows, then wipe them with a clean microfibre cloth for a crystal-clear finish.

Step 7: Final check and finishing touches
Inspect your car after cleaning and check for any leftover dirt or water droplets. Wipe away any wet drops with a dry microfibre cloth. If needed, wipe the car down once more so the surface is completely dry.

Tips for using a steam cleaner in your car

Don't use too much steam: Too much steam can leave excess moisture in your car, which can damage fabric upholstery and electronics.
Clean in a cool, dry place: Ideally, clean your car outside or somewhere well ventilated, so moisture can evaporate quickly.
Look after your steam cleaner: Clean your steam cleaner regularly to extend its life. Wipe the nozzles with a damp cloth too, and store the machine in a cool, dry place.

Conclusion: cleaning your car with a steam cleaner is definitely a good choice!

Cleaning your car with a steam cleaner is an effective, eco-friendly way to give your vehicle a thorough clean. It keeps your car's interior in top condition. With different attachments (such as those for the Techweise steam cleaners), you can clean your home as well as your car, which makes these machines an even better investment!
