Think your check is safe after you fill it out? Think again...

Your writing can be removed using a procedure called "check washing." A solvent is used - usually rubbing alcohol or nail polish remover - to fade out or completely remove what you've put on your check.

Here's a before and after picture:

The check is now ready for a new amount (I'm guessing larger than $10) and a new recipient.

An even better trick for the forger is to cover your signature so it remains in place while everything else is removed.

So how can you avoid becoming a victim of this trick?

Use the right pen.

Based on the excellent testing of Sean Kane, he found that gel pens worked best at resisting these check washing procedures.
