I thought I'd add another tip that you might find helpful, if you are really obsessed, like I can be at times. <img src='style_emoticons//laugh.gif’ border=’0′ style=’vertical-align:middle’ alt=’laugh.gif’ /> I found Goo Gone (mixed with patience) can take a foil box that has tape and/or tape residue and make it look like new. Use a clean rag and put the Goo Gone on the rag, not the box, and rub gently. If you don't soak the box, the foil will just shine up and show no trace of the Goo Gone or the tape residue. Just make sure you wipe up all the Goo Gone.
Also, if you have stickers on your white or paper boxes that you want to get rid of without ripping up the box, try taking a blow dryer to the sticker to loosen the adhesive. Some stickers will come right off, but some are very stubborn on paper and cardboard, so BE CAREFUL. I have cleaned up boxes that had 10-year old+ tape on them and they look good as new. Patience is the key.
Anyone else got any tips to share? This could be a great topic. <img src='style_emoticons//smile.gif’ border=’0′ style=’vertical-align:middle’ alt=’smile.gif’ />
