Once you stain white patent leather its hard to remove, so just be aware of dye transfer from your clothes, especially jeans. Also sometimes you'll find you get scuff marks, it is very important to remove the scuff mark right away as the scuff can also leave a stain.
I got brown scuffs on my white patent purse. I left them for 3 days though before removing with non acetone nail polish remover and now have very light brown stains instead. You wouldn't notice them if you didn't know but its still very annoying.
There are many good patent leather cleaning and protection products available. You can do some research on the internet or local mall to see what you're most comfortable with using.
Easy household tips for patent leather:
For general cleaning a clean damp cloth is best, for scuffs and stains non acetone nail polish remover and for shine petroleum jelly.
