Firstly it is important to hone your search to a specific kind of boot. After you have done that you can be sure to receive better results about the upkeep of your boots. Some general tips include brushing off dirt with a metal bristle brush, wiping off the inside of boots with a wet, soapy rag, never drying boots near intense heat so as not to destroy the leather, and removing the innersoles when drying. Information for the upkeep of boats could be found in several different areas....Of couse the first and most convienent way would be to do a search on the internet...there are hundreds of sites they would be helpful in field of boat repairs and Upkeep...The second approach would be to take a ride to the local Library...I am sure that the topic of boat upkeep and repairs would be a topic that would be available...And if you dont have a computer at home....Most library have access to computers where you could do a search there...With a librarians help,if needed...thanks
