Spring is in the air and that burst of energy in your step may lead to some extra cleaning around the house (or in this case your business)!

From hardwater build-up due to last summer’s sprinkler system to this past winter’s road grime, minerals can build up where you least expect them – on your roadside sign. Mineral deposits are one of the leading culprits in the appearance of a dingy looking sign, and we have a few tricks up our sleeve to help you make it look new again.

To get started, there are two important things to remember when cleaning your sign. The first is to never scrub the surface of the sign. Scrubbing can damage your sign’s finish or create shiny spots in the areas that you worked so hard to clean. The second critical rule is to give the cleaning product enough time to work. Limescale takes time to breakdown. If cleaning chemicals aren’t allowed enough time to do their job, you won’t see a difference because the mineral deposits will persevere. We suggest trying one of the following options for getting rid of those hard-to-remove stains.

  1. The first solution we recommend is CLR, which is an acronym for calcium, lime, and rust. (These also happen to be the minerals left behind by hardwater stains). CLR is known to be one of the most effective tools to tackle mineral deposits. To clean your sign, you’ll spray the cleaner on the stained area and allow it to sit for two minutes. Then you’ll rinse thoroughly and repeat if needed. Note, DO NOT use CLR if your sign is composed of raw metal such as aluminum, brass, or copper or if it is made of natural stone(s). CLR will damage these surfaces. The exception to this rule is if your sign is painted or clear coated aluminum. If you have any questions about using CLR on your sign, just reach out and we’ll advise you.
  2. White vinegar is another great choice for removing hard water deposits. Cleaning vinegar (greater than 5 percent acetic acid) should be diluted with distilled water at a 1 to 1 ratio. You won’t want to use tap water as it contains the same minerals that caused the hardwater stains to begin with. Once you have the vinegar and distilled water mixture ready, spray it on the affected surface of your sign and allow it to sit for at least 15 minutes. Then rinse and repeat if the stain persists. Vinegar is not recommended for signage with stone surfaces like marble or granite.
