Slide leaving grease/road stain on carpet

[Oregon RVer]

We're newbie RVers. We just returned from our first RVing adventure and parked our 5er in the driveway to perform some winterization tasks (prior to storing). When we ran the slide out we noticed a black stain in the carpet where the left-side slide rests when retracted.
Three questions:
Where did this stain come from?
How do we fix the problem so it doesn't happen again?
What do we use to get the stain out?
Thanks so much for your help!

Sounds like some excess grease from the slide track. I don't know your 5er so not sure how best to access the the track to clean off the excess. I would think as the slide begins to move in (retract) it will tilt up just a bit. This may be enough for you to clean of the excess.

I use Resolve on my carpet with good results

Remove ALL grease/oil from the slide underside, and do not use it again. It collects road grit and dirt. This actually makes the mechanism work harder and wear faster, as the grease/dirt mixture combines to become a crude grinding compound.
I use "Dri-Slide" lubricating compound. It sprays on wet, quickly dries and leaves a dry lubricating finish.

As to how to prevent stains and wear from the slide, I have used Slideout-Slickers" ever since our 5er was a month old. They are made by Lippert Components Industries (am I the only one to see the irony?) When new, the slides actually cut the carpet. The dealer replaced the carpet and re-adjusted the slides, which did nothing to stop carpet wear.Our Slideout Slickers are now 6 years old and still quite thick, although deeply scarred with cuts and scratches. One set is two pieces, so one needs a set for each slide room over carpet.
