A small side note removing carpet from lids. Everyone is using different methods. I found the cheapest easy method is acetone.
Put in a spray bottle, coat lids well and carpet peels off within one min.
I liked the goo gone method (same as above) but it took 24 hours to loosen the glue.
My lids are metal as I assume most are so a reaction was a non issue. Not to mention acetone is $12 a gallon compared to 45 for goo gone. Hopefully this can help someone .
