Mystery Stripes

[Cincinnati Kid]

I have these three orange/pink stripes in the floor next to a through-the-frame LCI slide. They are equally spaced, and it seems obvious that the slider is causing them.
I have been on the floor and watched the movement, both opening and closing.
There is nothing under the slide that could make those marks, just a particleboard surface above them. The slide never makes contact with the linoleum going in or out. There is nothing caught under the slide.
It’s a mystery.
The stains do not come off with any cleaner I have tried.
They are not dented or gouged, they look like they were done with an orange/pink marker.
The dealership was clueless about them.
Any ideas?

I have the same thing, but only in one area in our bathroom. It appears to me that in construction, the floors are marked for layout of where walls or other components would be installed as the unit is built.
Yours are a bit puzzling because that wouldn't be where a wall or cabinet would be placed.
Mine are impossible to remove, and seem to have spread slightly. I've wondered if it something bleeding up from underneath the vinyl, but it wouldn't be adhesive because Jayco does not glue the vinyl down except along the perimeter.
The only cleaner I haven't tried is AFTA, which professional vinyl installers use to clean adhesive etc off new vinyl flooring. I'm not sure this cheap vinyl would survive the chemicals in AFTA.

Could be caused by a similar problem many of us are having with the vinyl glue seeping up through the floor and causing rust looking stains-

Yours is a bit different in appearance, but the cause could be similar in that its something from underneath. I have the rust stains and nothing cleans them, even applied a controlled drop test of bleach; no effect. The stain is "in" the vinyl.

My unit is at the dealer now getting the entire vinyl floor replaced due to this. Part of the instructions from Jayco is to sand the wood floor to ensure no trace of the old glue is present for the new vinyl install. Thats how critical/delicate/whatever this relationship is between the vinyl being used and what comes in contact with it underneath.

I’ve got these on my FW as well. I put a runner down over them since it’s between the kitchen island and large slide. Out of warranty so the rug is my fix.
