At Rock Solid Doors, people always ask us about the best way to clean their doors safely and effectively, so it seemed like the right time to create a simple guide on how to thoroughly clean doors without causing any damage. Our experts contributed the following tips, tricks, and solutions to the problem of keeping your doors clean and functioning perfectly for years to come.

Why do I need to clean my doors?

Even the incredibly robust, durable composite doors we provide at Rock Solid Doors can benefit from the occasional wipe-down and clean. Some reasons why it is a good idea to stay on top of the job include:


Before rolling up your sleeves to clean your doors, a few useful products and items are necessary. Essential door-cleaning supplies you should prepare beforehand include:

Traditional household products for door cleaning

Specialised cleaning techniques

  1. Dust to remove cobwebs and loose dirt. A vacuum cleaner may be necessary for carved doors with deep recesses. 
  2. Mix warm water with mild dish soap
  3. Cloth/sponge the soapy solution onto the surface and wipe away, checking for stubborn marks
  4. Rinse the cloth/sponge and wipe away soap residue
  5. Dry with a clean, lint-free cloth

Maintenance tip — Apply wood polish or conditioner to nourish the surface and provide ongoing protection.

For metal doors, follow the same steps as for wooden doors, but substitute dish soap for an all-purpose cleaner if preferred and metal instead of wood polish. 

  1. Mix equal parts white vinegar and water in a spray bottle
  2. Spray onto the glass surface and leave for a few minutes
  3. Use a microfiber cloth/squeegee to clean away the residue. Make circular motions
  4. If glass is frosted and textured, use a soft brush or sponge
  5. Rinse clean with fresh water 
  6. Wipe dry with a lint-free cloth

As the toughest, lowest maintenance of all exterior doors, composite doors could not be easier to clean. Any mild soapy liquid or non-abrasive/corrosive spray-on cleaner will suffice. Simply apply it to the door, wipe away the dirt, and you’re done. 

Door hardware

For knobs, hinges, and handles, you can choose a universal cleaning spray or damp cloth with mild soap. If parts are rusted and tarnished, it is possible to rejuvenate them using cider vinegar. Remove the pieces from the door and let them sit in the liquid overnight. Clean thoroughly, dry and re-install; they should look significantly better.

How often should I clean exterior doors? 

Aside from obvious times (especially during winter) when doors start to look grubby and jaded, the frequency of cleaning depends on how heavy the usage, environmental factors, and the material of the door itself.  Speaking generally, it is safe to assume that once every three to six months, you should consider cleaning your doors, even if they appear relatively clean. 

Can I use a pressure washer? 

In professional hands, a pressure washer can be a magnificent piece of equipment. In the hands of an amateur, it can be a total liability. The chances of damaging, warping, or otherwise ruining your door are exponentially higher if you use a pressure washer. If you insist on having a go, set it as low as possible and test the pressure on a small area first. All this is irrelevant if you have composite doors, which can withstand virtually anything.

100% recommend Paul and Harry a great father and son team! I'm so pleased that we used them to supply and fit our new front door. Straightforward to deal with from start to finish and communication throughout was excellent. They are extremely knowledgeable and were able to offer advice and suggestions when we were choosing the door we wanted. Nothing was rushed during the installation with great attention to detail. They took away our old door and frame and left everything clean and tidy at the end of the job. Thank you, Harry, for taking the time to go through everything with us at the end of the job, much appreciated. I would not hesitate in using Paul and Harry again. Thank you both so much, we are so pleased!

Had a door fitted by these very friendly chaps about 18 months ago. We're very happy with it. When an issue arose with the mechanism, they came out and fixed it in about 5 minutes and it's as it if is brand new again. Very pleased, would highly recommend.

Highly recommend. We had our front door fitted by this lovely team. They were friendly, helpful, willing to listen to me debate options and provided helpful advice for choosing the right door for us. When he had a slight issue (no fault of their own) they came out to us the very next day and sorted it. Such a good supplier to work with!

Brilliant service. No hidden costs or fees and no heavy sales tactics. Very open and clear from the start, and they worked really hard to fit a great new door in our thinner than average doorway! Great value and great result. Will be recommending to all.

Highly recommend Rock Solid doors. We have used this friendly family company several times and have recommended them to others who have been equally impressed with the high standard of work and the product. We have received quick service and found them to be very reliable knowledgeable with no hard sell. The installations have been carried out professionally and they go the extra mile to ensure you are happy with everything. The external doors are robust and we are impressed with the quality of the product.

Faultless customer service from a fantastic company to do business with. From start to finish it’s been a pleasure buying composite doors from Rock Solid Doors – in fact, we were so impressed with the front door and installation service they provided (we opted for a Solidor Ludlow 2 with 2 x fully glazed side lights) that we got them back to supply our utility door (Windsor Solidor – fully glazed) shortly afterwards. Paul dealt with our initial queries promptly, came to measure on site and provided a competitive quote very efficiently. These guys are first-rate craftsmen and know their stuff: evidenced by working around a couple of quirky construction issues without any problem – leaving us really impressed with the end product. It’s great to come across a local business that takes pride in what they do, going the extra mile for customer satisfaction – we cannot recommend Rock Solid Doors highly enough! Thank you Paul and Harry!

Brilliant service from Paul at Rock Solid; our letter box seal had gone causing a slight leak - he responded immediately, attended this week and fixed with a new gasket. Would highly recommend the product and the service.

I ordered my Vogue Rock door with the Ocean glass from Rock Solid Doors at the end of 2021. I had a number of criteria when searching for my new entrance door. It’s ability to insulate had to be A rated. I also wanted it to have a good quality locking mechanism that is smooth in action. My new door needed to be modern with a pane that lets plenty of light in and thus goes lower than the half line on the door, while leaving sufficient height for the letter box, so it is sufficiently high to be comfortably reached by our postman. The Vogue Rock door provided all that and more. I love sailing and the Ocean glass design evokes the lines of a sail in a beautifully minimalistic fashion. It also makes the door look unique, which is always a bonus. During my search for the perfect door I had lots of technical questions too. Only Paul and his colleague from Rock Solid Doors were able to answer all my questions and provide a door that offered what I was looking for. They supplied and fitted my new door in early 2022. My heating bill has gone down noticeably, as a result. With the golden oak wood grain on the outside, my door looks beautiful and elegant. Everyone who comes to the house for the first-time comment on it. The multi-locking mechanism has a smooth action and it is easy to use. The white wood grain on the inside finishes off the hallway like a designer window and door in one. Paul and his colleague went out of their way to make sure that I have the door and the finish just, as I wanted and that it worked seamlessly there on. We could not be happier. Thank You!
