melting step carpet

they look like they have been on the steps for the last 20 years of so. I am wondering what they are going to say when you take them back.

No cleaning products were used at all. They wrap around the step and are hooked with 4 springs. No adhesive...

There may be some glue used in the manufacturing process.

Are they glued on and if so, with what glue? Some have pretty strong solvents that will eat synthetics lickety-split.

Did you use any cleaning products to clean the floor?

No, nothing was spilled on them. The TT is brand new and hasn't left the driveway yet. Tomorrow:B I'm not sure that I even have anything strong enough to do that. I'm not sure if gas would melt it like that. This looks like it was done with heat. Both edges of the top step are curling up. The steps were out and it was the sunny side, but that's not unusual. They looked fine out of the package. The ones on the other TT lasted for several years...

Wonder if maybe you didn't run through some puddle of something noxious, that sprayed up on the steps.

Very odd though...

Glad that you will get a refund on them.

That is weird....:h
Did something get spilled on them while loading?
