Stains are annoying whenever they occur, but when you’re on the go it can be a bigger concern. Partly because you might not have something to change into within reach, and partly because you might have had plans to wear the item again if you happen to be on vacation.
The key is to carry some stain fighting products on you to make sure that you can clean up before the stain sets in.
Shout wipes are one common option, which can easily be tossed into a purse or bag to be used on the go. Tide to Go is a similar option in a pen form, and there are many off brands that offer the same stain-fighting power for slightly cheaper prices.
Worst case scenario using some soda water and a napkin can be the best bet.
