Hi Dan
i make Bras for Class "A" motorcoaches and this is what we tell our customers. the bra must be clean and dry when installed. and is used for driving only.
not for general storage or full time. it can be run in the rain, cold, snow, heat and any other condition. but must be removed cleaned and dried and never left
on all the time. some customers listen others do what they want. i cant and wont stop them from doing what they want to. i can only warn them. hope this
helps. also the bra should be rolled for storage never folded. but that is the owners issue from there.
heck i even had a customer tell me he uses easy off oven cleaner to get the bugs off. (NOT RECOMMENDED) he was on his 2nd bra in 4 years since the
other one just fell apart for some reason and im sure it had nothing to do with the way he cleaned it.
i can print my cleaning and care instructions if wanted for all to see. i dont make bras for cars and vans there genaric and are usually made in mass quantity.
