My husbands working from home which means more; running, cycling & dog walking…which means even stinkier trainers, cycle shoes & wellies! None of which can go in the machine!
Cupboards stink, my porch stinks..there’s no location safe from them!
Bicarb inside then hoover it out. Also rubbing alcohol but I’m not sure I would wanna get my hands inside the shoe to rub it (damp cotton pad, rub all the inside parts then allow to evaporate).
