How To Clean Old Rusty License Plates

Tips for Cleaning and Spiffing Up Plates

License plates rarely stay make clean and in good condition for long. While mounted to a vehicle, they become splashed with dirt, mud, salt, snowfall, bugs, stones, and years of temperature extremes and UV exposure. Subsequently being removed, they might be set aside out of the elements...or they might be unceremoniously tacked to a garage wall or barn roof; left exposed to rust away for many years more than. License plates nearly always need to be cleaned or reconditioned before being appreciated as collectibles...and if there'south any tip I can give, information technology's that a proficient corporeality of hobby fourth dimension is spent over the sink!

Calorie-free dirt

There are many ways to clean license plates, and some of them aren't very intensive at all. My offset weapon of defense force is the most prosaic: Soap or detergent, water, and a washcloth. For contempo plates in relatively good condition, this is ofttimes all that's necessary to prepare them for brandish or storage. If a thick layer of dirt or greasy crud is caked on to the back, a scouring pad and elbow grease will do.

Lite rust stains

Rust stains (equally opposed to actual rust) may be removed with Comet, or any other scouring pulverization containing bleach. Typically I'll wet the surface, sprinkle the powder on, look for it to soak for a few minutes, scrub the affected areas with an former soft-bristle toothbrush, and repeat if necessary. This works wonders on newer plates with Scotchlite sheeting, simply I'm hesitant to try it on older ones.

Surface cleaning

An ordinary rubber pencil eraser can remove dust and clay, bring out original gloss, and remove surface oxidation from the surface of painted plates. (It won't practise much on Scotchlite, though.) My '85 California looked both darker and bluer afterwards putting information technology through this handling. (I also took the freedom of touching upwardly the month sticker to get in expect more displayable, until a better plate came forth...use the same judgment and disclosure that you would anywhere when repainting plates.)

This 1939 Wisconsin besides shined up considerably subsequently a uncomplicated scrub with a Pink Pearl:

Rust

Through Jon Upton, I discovered the technique of using CLR...the acidic kitchen and bathroom cleaner...as a tool for removing rust outright from older plates. This technique tin be hit or miss, as pigment consistencies vary wildly and two different plates in like condition may produce wildly dissimilar results. Even so, CLR is potent and the closest thing to a miracle cleaner I've used then far. The kickoff guinea pig of my experimentation was a 1925 Illinois, where I scored some very solid results:

I soaked the plate in a shallow vat of CLR for half an hr, then scrubbed the surface with cotton pads. Equally I anticipated, it turned out beautifully; easily jumping from off-white to good in condition. The paint was hardy, non chalky, and the rust stains on the numbers lifted off with a modicum of endeavor. The groundwork cleared up similarly: Information technology was tar black when I started, simply afterward cleaning information technology was the shade of dark brown that it should be.

A splotchy 1940 Wisconsin was another success story; brightening up considerably after being soaked in CLR for an hour and a half. I had to be careful, though, equally the reddish paint was liable to come off if I rubbed the surface too hard. Longer soaks in the chemical are more than likely to remove rust, merely soften the paint considerably.

This '32 Wisconsin was more of a challenge, and more of an ambiguous result. Later being soaked for two hours, there was seemingly no change at all. Simply after letting information technology air out a bit, I scrubbed and scrubbed and was able to lighten the background to the same shade of yellow as the amend half of the pair (beneath), which I left lone. The color was definitely brighter than it used to exist, but there wasn't much I could do about the pockmarking of the groundwork pigment and I dealt with a bit of pigment loss on the numbers.

The biggest claiming of my experiments was a 1920 Wisconsin truck plate. No pigment was left on the raised surfaces, and any was left of the background was completely subsumed by surface rust. Yet, I had aught to lose...and after a very long soak and scrub, about half of the original background paint became visible by the terminate. Sadly these plates were colored rust-chocolate-brown when new, and then you may have to have my word on it.

After Stage 1 was done, I decided to go along my experiments past making the '20 the canvas of my first amateur repaint job...an exercise in either luminescence or stupidity:

CLR generally seems to exist a better technique for plates with dark backgrounds than light ones, since flaws such as pockmarking won't be as visible. Utilize your educated judgment, though...especially when portions of the background paint are missing entirely. I gave this 1942 Wisconsin a soak and scrub in the CLR bath, exposing some bare metal in the procedure. In retrospect, I would have been ameliorate off leaving it lonely: The flaws were less conspicuous and blended in with the background better when they were rust-chocolate-brown.

Also, don't try CLR on a plate with Scotchlite cogitating sheeting. It'll remove the rust, just it'll likewise crusade the sheeting to blister, skin, and crumble wherever a breach in the coating exists.

Sticker removal

While digging through piles of plates looking for August 1985 expirations for my birthyear run, I've sometimes had to create what I need by taking Baronial '86s, '87s, and beyond and dent downwards the sticker stack. The most user-friendly mode to do this is to heat the corner of the plate with a hair dryer for half a infinitesimal. In one case the adhesive is softened, you can catch the corner of the undesired sticker(s) with your fingernail and carefully skin them off without dissentious anything underneath. Occasionally, hot water will have the aforementioned event...so be careful when washing plates, or you might wind up removing stickers without even trying!

When approaching this topic, "employ audio judgment" is a lesson that tin can't be stressed strongly enough. Be enlightened of historical context and accuracy: A blackness California plate pared down to the 1960s in the right sticker well volition be inaccurate if you leave the calendar month sticker in the left well, since those weren't introduced until 1976. If you lot skin a plate with 25 years of wear down to a single year sticker, it will look ridiculous no matter what information technology is. And if you indiscriminately "naturalize" all the plates in your trade box in the hope of boosting the values...you are non going to win whatsoever friends in the hobby at all.

Storage

I currently keep nearly of my collection stashed in Sterilite plastic containers. They're the right size for almost l-sixty plates each, they're stackable, and they're also long enough to accomodate things that are slightly oversize such as 1930s and 1940s Wisconsin.

Beware of defective sheeting

It's best to store license plates in a absurd, dry out place. Although hunks of aluminum might seem impervious to temperature and humidity fluctuations, don't be also confident nearly your collection. A good number of recent plates with 3M cogitating sheeting (particularly those from the 2008-09 timeframe) are decumbent to quickly deteriorating and turning greyness after being subjected to some combination of heat and humidity...even if they've been placed in storage the entire fourth dimension.

The same plate...earlier it spent a summer in a storage unit, and after.

Another give-and-take...

Information technology'south a good idea to apply rubber gloves when handling chemicals, when cleaning license plates or otherwise. Please don't mutter to me if you dissolve your hands in acid by not doing so.
