Stoner's window cleaning tool

[Coopers ST]

I have a question about the Stoner's window cleaning tool. I have one of these and find it fantastic for getting way down by the dash of my Focus ST that I otherwise could not reach. My question though is, it came with three different bonnets. What are they for, and when should you use them?

Thanks again!

White - scrub
Yellow - heavy duty cleaning
Blue - normal cleaning

At least that's how I've found to best use em. I usually don't need the white...mostly use blue and would like at least one more.
