How long do you keep your squeegees

[Maxie]

How long do you keep your squeegees and how do you know when it's time to change them?
Some of mine are really old.

We keep ours a long time since we sharpen them.  Without a sharpener we used to flip them in the holders getting longer use with them when they were getting pretty dull testing with our finger tips.

I'd be interested in what the squeegee manufaturers would say.... how long? is the edge sharp enough....

Assuming sharpening maintenance, over the years I have seen two other conditions that signalled the end of the line. Depending on chemicals being used, the squeegees would eventually either soften or stiffen.

If you sharpen, and they stop taking an edge, there's a good clue. Too much chemical & time, and I've seen them just generate gummy boogers on the grinder. (And there's nothing like reaching for one you haven't used in a while and realizing the blade is sticky. That one's a goner!)

We usually start around 15" but the corners wear down a bit after a while. Sorry...couldn't resist!
