Belt stains on knickers

You can find it in the Automotive section of Wal-Mart. Don't dilute it, just spray it straight on the stain and wash with your whites in hot water. Works like a charm.

I actually used it on an old rag cleaning my Harley once and it took most of the grease stains off of the rag.

Warning: Do not use it on your socks very often - it will make them deteriorate very quickly.
