How Often To Change Rubber

With all the incredible innovation in window cleaning using advanced science and engineering, sometimes nothing beats a simple squeegee and
t-bar. Low rise products appeal to every window cleaner, regardless of company size or the length of time you’ve been in the industry. In fact, replacement rubber is our top selling product.

Of course, that’s because changing rubber is a necessary part of every window cleaner’s routine. So how often should you be changing your rubber?

What are other window cleaners saying?

We polled our Facebook followers and asked them the same thing. According to them, many window cleaners cleaning residential will change their rubber after every house. Some window cleaners said that they flipped their rubber in between jobs and replaced everything after that.

Commercial cleaning was a little less involved. Window cleaners agreed that their rubber lasts longer, some mentioned that they will squeeze as much time out of their rubber as possible by cutting the spent edges and continuing on for as much time as possible.

We can’t answer that question…

But here’s the thing. There is no exact answer. Changing rubber is on a “need to” basis. There are so many variables that affect how rubber in a squeegee performs. Consider, it matters the way the rubber is stored, the time of year (summer is busier for window cleaners and more jobs mean more rubber being used), the weather, what kind of job it is (residential vs commercial), how many times it’s used, the kind of rubber (hard vs soft), the pressure being applied, and even the type of window (hydrophobic vs hydrophilic).

Because we aren’t asking the right question.

But there are some things that can be said for certain. When you’re buying rubber, assume that each piece of rubber will last you one job, so that one order of rubber (a dozen pieces) will last you for at least twelve jobs. When your cleaning routine becomes more systematic, rubber can be purchased in a gross quantities (usually 144 pieces).

The other thing that can be said for certain are the signs that you need to change your rubber. They are easily recognizable because essentially, the rubber tells you.

Visual Clues

Looking at the rubber, look for cracks. This is a sign that the rubber is dried out and should be replaced. Also, the corners should be square. If they are round, the rubber should be replaced. Otherwise, let the cleaning results talk for themselves. If there are any streaks, trails, if it seems hard to pull, or your slowing yourself down because you’re having to spend extra time over-detailing, it’s time to do something about your rubber.


Many window cleaners will flip the rubber at this point. This will extend the life of the squeegee rubber but when you notice something less than perfection, it means that the rubber needs to be changed completely.
