Longaberger basket hand woven The last year they ever did that

Last year of Longenberger hand woven baskets. Has the initials and year signed on the bottom. 8inW 5in len & 5 deep with a wood lid, leather straps for lid and to keep lid closed. Has handled as well. I kept it clean not clean but the way I purchased it because I felt like the people who were looking for this type of product wanted to clean it themselves I don’t feel like I should be cleaning this I don’t want to ruin it this is very historic I mean this is the last year they hand woven baskets ever, people keep saying to clean it but no one gives me any ideas on what to use so if you’re going to pipe up or if you have some knowledge I have more than willing to do what I can to get it cleaned up and keep the wood in the great condition
