Johnny,
Ed has good advice about using the orange paint remover, that is what I use and it works great. If you follow his advice on shipping your grips, they should be ok.
If you want to try cleaning your grips yourself:
Remove the lacquer with the orange stuff. Then use Ron's method or my method to clean them. After they are completely dry, apply a little Tung Oil or Watco.
I use Simple Green to clean grips. It is a degreaser sold at Wall Mart and most auto supply stores. Scrub them with a soft toothbrush and then wash off. I agree with Ron that Watco is much better than Linseed Oil. Tung Oil is also very good. I usually brush on a little Tung Oil after checkering and staining grips. It really brings out the color of the wood.
If your grips need the checkering freshened after cleaning them, the price is $55 including return P&I. If you want me to clean and/or rechecker them, I will strip, clean & oil for $20 including return P&I. If they need recheckering after cleaning, I will only charge $10 for the striping & cleaning + $55 for checkering & return P&I.
