Sign Cleaning

Sign cleaning plays an integral role in most office maintenance routines. It is an important phase of spring cleaning but more than that many companies employ their window cleaners to clean the signs along with the regular window clean. This avoids the build-up of dirt and mineral deposits and more importantly upholds your business image. After all, this is a ‘sign’ to potential customers of the quality and professionalism you provide. Dirty signs could most definitely be sending the wrong kind of message. If you wish to save time, money and achieve sparkling signs, you should invest in skilled window and sign cleaners who can clean both your signs, windows, frames, and facades on a regular basis. The professionals are trained to work with the right equipment, tools and methods for top-notch, stunning signs and surroundings.

The Right Season


Signs should be cleaned at the very least, twice a year. Ideally, spring and autumn. This is when signs are affected by salt water, busy street dust and mildew. Letting dust, mildew and salt deposits remain on signs for a long time will result in permanent damage. Unlike glass that can be resurfaced, damage to signs is often irreversible or very expensive to fix. In winter rain can wash contaminants from surrounding walls onto the sign and can cause additional dirt and stains. We therefore recommend having your signs professionally cleaned around November.

The Right Method


There are several different types of sign cleaning methods and many various elevated platforms and reach systems for cleaning signs. Some techniques such as pressure cleaning can cause irreversible damage. Handle with care!

The Right Time


In accordance with the good old adage, “There is a time for everything, a time to grow and a time to reap”, there is also a good time for sign cleaning. It is best not to clean signs on harsh hot days or during a storm or rainy weather. Choose a cool, cloudier day.

Four Types of Sign Cleaning Services


Regardless of the method used, sign cleaning should be carried out regularly. Professional sign cleaners offer three different types of services.

1) Regular sign cleaning is performed during regular time intervals however; it doesn’t necessarily stick to a specific schedule.

2) Routine sign cleaning happens within predestined time-gaps. And, it is extremely important for proper building maintenance. During normal conditions, routine sign cleaning is done on a three monthly basis. Routine periodic care will prevent too-much dust and grime build-up and as a result will increase the overall lifetime on your signs and will keep them looking spick and span.

3) Remodel sign cleaning is a specialized service used to remove silicone, residual paint, cement, and other hard-to-remove deposits – High skill-set required.

4) Internal sign cleaning is a more specialized field and could more correctly be coined ‘sign maintenance’. This involves opening the sign, cleaning the interior with specialize micro fiber pads, replacing globes, re-taping wires, and more.

Types of Sign Cleaning

1. The Squeegee Method
An older tried and tested method used by professional sign cleaners is the ‘Squeegee’ technique. This method can still be effectively used on flat signs at reasonably low heights from the ground or from a work platform. During this method, detergent is applied on to the sign surface and wiped using a fine-tuned squeegee blade. With the right techniques and tools, you will be able to achieve streak free results. Unfortunately, the squeegee method is limited by many factors. The procedure expects direct application and contact with the sign surface. And, this increases the risks of the sign being scratched.

2. De-Ionizing
Another powerful tried and tested technique used to clean signs of various shapes and sizes would be De-ionized water. When compared against the humble squeegee, De-ionized water-fed cleaning is truly effective and efficient. It is an interesting process that uses membranes to remove dissolved minerals from the water leaving the sign spot-free. The method is extremely useful for hard-to-reach signs and can be very cost effective.
