Scumballs and Scumbugs-Do they work?

[Warkovision]

Wondering what the concensus here was. Are they worth it? Is it a good idea? I've been dealing with mild scum line in my Vista. No huge deal. I've seen in other threads that some people use Doc's tub rub. Is this a better bet?

Warkie,
I don't know about the scum floaters but I do like the tub rub very much and recommend it highly.

Most of the scumballs I know don't work.........they collect unemployment !  

Just trying to inject a little humor !

(I know........very little)

Yes, the products Scumballs and Scumbugs do work.

I bought some from Doc, and you will be amazed how dirty they really get!

They all have one thing in common: Polypropylene. It is a polymer that absorbs oil but not water. Sort of like the way my brother-in-law absorb my money but not other relative's money.

Anyway, my point is that they all work pretty much the same.

How long do they last and how do you know when to replace them ?  Any kind better than others ?

My first scum bug lasted about a year and a half.  I rinse it out on a weekly basis.

I think as Chas stated they are all about the same.  I think I read somewhere that it will get ratty looking and that is when they should get replaced.

My dealer said that the one I got with my spa will sink when it dies.

Like a real one - I guess?
