Depends how clean you want them. The basket weaves are a challenge. I use Purple Power to strip them, its avail at oreillys and Walmart. Spray it on and let it dwell for a minute. I had in the past a set of drill attachments that had a little cone brush that did a good job of getting the the small spaces clean. Once they are clean, I used to wax them, but have graduated to ceramic coating. Its kind of pricey but it works great.
Med. Wedgewood blue might be my fav. Ford color. Post a pic when you are done!
