Tough white coating on old screwdriver handles
Hello,
Couldn't find anything about this, so thought I'd ask here. I have quite a few old screwdrivers that have been stored in metal toolboxes in a damp, but not wet, basement. Over the years I've noticed a tough, white coating appear on the handles of some of the oldest screwdrivers. Is this some sort of mildew, or a chemical separation of the plastic of the handles, or...? I've found it pretty difficult to clean this stuff off - is there a particular solvent that would be best to use? Thanks for any info... |

I would agree that it is simple deterioration of the plastic. To
"spruce them up," you might see if the "Fusion" plastic paint in some suitable color might help. Make sure to get all the grease off -- a good detergent, or run them through the dishwasher (the chief domestic engineer might not be pleased, however). |

Older cellulose acetate/butyrate plastics would absorb a bit of moisture and 'whiten'. When thoroughly dried, the effect disappeared. Try drying them out by exposure to a modest temperature of maybe 140 F or so for a while, That should not distort the plastic and ought to speed up any moisture migration. Worth a try. Joe |

It temporarily disolves plastic and turns plastic to goo. If you use a flash coating to "spruce it up" be very carefull not to touch it while it is in the goo state. Touch it and one's fingerprint will become a permenant feature. |

Thanks for all the replies, folks. Thought I had a
super-fungus rampant in my toolboxes. Cheers. |

I have the same problem with specific tools, not necessarily old ones, and once I found out it wasn't mold, I stopped worrying about it. -- Use your propane or MAPP torch on it.

I don't know the cause of this problem, but the handles do clean up nicely with a scotch pad and some water. I found the coating comes off very easily. |

I am willing to bet Mr. Land found the answer about eight years ago right after he posted his question. Sheesh. I wonder is this web forum poster has figured how to get the stink off of Chinese screwdriver plastic handles, too. |
