yeah that is how her husband had done it and the dryer I took out a few years ago was 59 years old. Ive been in the crawl space past and no visual mold under there or issues shes not running hot and think less from that.. Her dryer is in the kitchen and been that way since it was put in then i gave her my maytag when hers finally packed it in. Had to cut my machine apart and pipe it out the bottom then cut a new hole in her floor and plug the old. Turned into an adventure more so when i found a double joist in the floor and spacing was already less than 16"
Good point about seeing more ill ask her again today sounds like she did the sugar and water and borax but going to check with her daughter today.
