How to Properly Clean Steel Siding

Steel siding is one of the most exciting exterior home remodeling products to emerge recently.  It’s durable, it’s beautiful, and it’s virtually maintenance-free.  But it does require a good cleaning once in awhile, because as far as we know, a self-cleaning siding product has yet to hit the market.

With the muddy spring we’re having, chances are that your siding is going to need a good cleaning as a part of your outdoor spring cleaning and home maintenance.  If your home is sided with a product such as steel residential siding from United States Seamless, you’ll want to clean it properly.  Steel has different cleaning requirements than wood or vinyl; here are the specifics:

  • While a power washer might be a little too aggressive for wood or vinyl unless you’re a professional, it’s the best tool for cleaning steel siding.
  • Chemicals you might use on wood or vinyl siding can cause damage to steel.  Put those away and simply make up a solution of 1/3 cup liquid laundry detergent and 6 gallons of water to use with the pressure washer.
  • Water and electricity don’t mix.  Make sure you turn off any breakers providing service to any exterior electrical – that includes lights and outdoor outlets.
  • Take a long-handled tool such as a deck brush or a telescoping handled brush and a bucket of plain water to first loosen any grime and dirt.  The brush should be soft bristled.   First stroke horizontally, then vertically to loosen anything that has been caked on.
  • Mold and mildew can build up in any areas where moisture might be trapped.  If that’s the case, apply a 1:3 solution of regular household bleach and water with a spray bottle before power washing.
  • Set your power washer on the lowest setting to apply the cleaning solution.  If you’ve never used one before, it’s a good idea to practice on a hard-to-damage spot such as your driveway or sidewalk before turning it on your house, because even set on low it packs quite a wallop.
  • Working in sections, rinse a washed area down with plain water from your garden hose.  Don’t let the soapy solution dry on the siding.
  • Put everything away – you’re done!  It might not be self-cleaning, but at least your siding is self-drying.

After a hailstorm, we needed to repair our siding, fix our roof and replace some storm windows. We were fortunate to find Quarve as we couldn’t find another contractor who was willing to take on the entire job. The best part about with working with Pat Quarve was the attention to design detail. Quarve was also able to work with the insurance company to help negotiate a fair settlement.
Linda and Jim, Anoka

From the beginning, we had a very positive experience with Pat Quarve. It was less about the sale and more about how well Quarve was going to put the finishing touch on our project. We were also impressed at how well the crew worked together, as a team, efficiently doing the job right the first time! Should any prospective clients wish to see Quarve perfection, we invite them to come past our home and see for themselves.

Denise and I want to let you know how pleased we are with our new roof. Even more important was the whole experience with your company. The crew was terrific as were the people in the office in helping us manage all of the communication and paperwork with the insurance company, mortgage company and the city. We would definitely work with you again and recommend you to others.
Steve, Eden Prairie

Thank you and your staff for partnering with us on our green project. You went above and beyond to educate us, provide options, guide us from start to finish and help us make decisions that worked for us as well as the environment. We felt that Pat was genuinely concerned about meeting our needs and providing products that are environmentally friendly. We will enjoy the improvements for years to come.
Chuck & Kathy, Roseville

We want to thank you for the recent work Quarve Contracting completed on our home. The roof, gutters and shutters looks great! Pat suggested a new roof color and shutters that have really updated the look of our home. Many friends have commented on the new look and we couldn’t be happier! We will call Quarve Contracting again if another construction project is needed at our house.
Tammi and Randy, Blaine

We would like to thank you for a great job on our house. We chose Quarve because they displayed professionalism from the start and we knew they were very quality driven. Anybody can up siding, roofing and gutters but is it going to last and meet state codes? This is important to protect our investment. Quarve exceeded all of our expectations. Thank you to Quarve for a great job!!
Bob and Rachelle, Cambridge

We want to let you know how very impressed we are with how you handled replacing our roof after hail damage. It seems to be a rare occasion that you can hire a contractor who is not only professional and innovative in business practices but also used top quality products and actually does what they say they will do! You helped us see there really is a difference in who you hire as a contractor – you take the cake! To us, Quarve Contracting stands for integrity, quality and professionalism.
Leo and Lisa, Lino Lakes

The quality of Quarve Contracting’s work and the professionalism of the crew was outstanding! We’ve recommended Quarve to three friends, all of whom selected Quarve to do their siding. Each homeowner was impressed with the completed work. We continue to recommend Quarve for their unwavering commitment to customer service and quality workmanship at a fair price.
Jim and Jill, Shoreview

Our house looks great and the whole experience was pleasant and hassle-free. We loved the work they did so well that we hired them on another project and recommended them to friends and family. Quarve Contracting is not only a step above the rest in the construction field, they are leaps and bounds above the rest.
