How Often To Change Rubber

With all the incredible innovation in window cleaning that applies 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 how long you’ve been in the industry. In fact, replacement rubber is our top-selling product.

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 between jobs and replaced everything after that.

Commercial cleaning was a little less involved. Window cleaners agreed their rubber lasted longer, some mentioned that they would squeeze as much out of their rubber as they could by cutting the spent edges before continuing for as long 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. Here are a few considerations: how the rubber is stored; the time of year (summer is busier for window cleaners, and more jobs means more rubber is used); the weather; what kind of job it is (residential vs. commercial); how many times it’s used; the type 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.

However, some things are 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 gross (usually 144 pieces).

Another certainty that you need to change your rubber are the numerous signs. They are easily recognizable because the rubber tells you.

Visual Clues

When examining the rubber, check for cracks, a sign that the rubber is dried out and needs replacing. 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 you’re slowing yourself down because you have to spend extra time over-detailing, it’s time to change your rubber.

Flip

At this point, many window cleaners will flip the rubber, which will extend the life of the squeegee rubber. But when you notice results that are less than perfect, it means the rubber needs to be replaced.
