I work away for 10 days at a time (8 work days) and only have limited (4) polyester polos for work. Over winter or when I'm just in the office, I can get two days out of each shirt but over summer or if I'm in the factory, I'll only get one day. I would normally just hand wash the four shirts in the kitchen sink and drip dry over the weekend, but i got to thinking after a dishwasher just got installed…
Came across this on youtube, if they're not heavily soiled I should be in business I recon.
Would have thought no. I mean you can do anything once, but what about the high temperatures ruining clothing fibres?
