Didn’t run the tumbler on the hottest setting, it doesn’t need to be hot hot.
Pillow case absorded any excess - we aren’t talking about loads of thick layers of wax though that ‘sloughed’ off the coat or anything. I just found it hard to get the wax ‘evenly’ spread using a hairdryer. Tumbler evened it up nicely. Also I kept checking it as I wasn’t sure how long it would need, so it was having maybe 10min bursts?
But. Yes good point, careful attention and vigilance required.
I did not ask permission from SWMBO. I didn’t ask her permission before putting a bunch of aluminium car parts through the dishwasher either - got away with that aswell
It’s all in the timing (ideally when she is at work!)
My downfall was using the oven to bake paint onto something - the smell gave me away when she got home
