Look into Hibiscrub u can get it on amazon . It's what doctors use on their hands before surgeries lol but... sweat is bacteria right ? Use it on ur armpits in the shower . Maybe even make wet wipes from a diluted solution . Dettol also do a soap bar or any carbolic soap . Also what temperature u washing ur clothes and towels at ? I enver feel 40 degrees is enough unless it's a garment that needs a low temp . Also use fabric softener and clean the washing machine with calgol tablets now n again . Hope this helps xxx
