How Do You Wash Outdoor Signs?

Outdoor signage needs love too. Bird droppings, dust, dirt, it all adds up and washing your signs extends the life of the finish.

Since archi­tec­tur­al sig­nage, like we man­u­fac­ture, has an auto­mo­tive grade fin­ish you wash your sign like you hand wash a car.

  1. Get your­self a good car sham­poo.’ This type of soap con­tains a wax that will help to pre­serve and pro­tect the paint­ed sur­face. Here are some at vary­ing price points. Dawn soap always works in a pinch too.

  2. Soft sponges and/​or soft brush­es with long han­dles work well depend­ing on the size and loca­tion of the sign(s). Gen­tly clean, don’t scrub, the sig­nage with a nice lath­er. Don’t wor­ry about get­ting soap in places it shouldn’t be, it’s an exte­ri­or sign and with­stands the elements.

  3. Light­ly spray the sign mak­ing sure no soap residue remains. Use a gar­den hose or a light spray. Do not blast the sign with a high pres­sure washer.

  4. Clean sign!

    Washing Outdoor Signage


Nev­er use paper tow­els on the acrylic sur­faces (rout­ed let­ter­ing or most illu­mi­nat­ed aspects).
Nev­er use a high pres­sure wash­er.
Nev­er use course cloths or clean­ing brush­es.
Nev­er use deter­gents that con­tain abra­sives (like Comet or sim­i­lar).
Nev­er use methy­lat­ed spir­its, sol­vents, or acids of any kind. 


Always make sure irri­ga­tion sys­tems are NOT direct­ly hit­ting any of sig­nage.
Always use clean, soft, and damp cloths with mild detergents.


All paint­ed and plas­tic com­po­nents do fade over time. But using smart col­or selec­tion, avoid­ing direct sun­light, and reg­u­lar clean­ing high qual­i­ty sig­nage can look great for years!
