Caring for Plastic Doll House Furniture

Doll houses, miniatures and furniture have been enchanting the young and oldfor hundreds (and possibly millions) of years. Over those years, many different materials have beenused to fabricate and manufacture doll house furniture. Most people contemplate earlyminiatures being produced from wood, fabricand metal. (Have you ever wondered if cave girlsand their mothers enjoyed rearranging their doll's stones and pebbles next to the camp fire?)As history progressed into the 1940's,manufacturers turned to plastic as the material of choice for doll house furniture. This guide discusses someof thestorage andmaintenancechallenges faced by the vintage plastic doll house furniture collectors of today.
Why Plastic?
Plastic became the choice materialfor American doll house furnituremanufacturers (and other toy manufacturers) in the 1940'sduring World War II.Wood and metal werenecessary materials inthe war effort and therefore the "relatively" new process ofplastic moulding became more widely integrated into the domestic marketplace at that time. Plasticis still being usedtoday because of its durability and itslow labor costof production.
Storage and Display Challenges
Yes, plastic is durable in the sense that it will not rust or rot, but it has its weaknesses. Still, the plastic of yesterday was not quite as hardy as the plastic of today.Even though vintage pieces of Renwal, Marx, Plasco, and Jaydon willstill exist millions of years from now, the condition inwhich they will exist is the real question.This section will discuss several of plastic's"kryptonites"and what you can do to protect your collection.
Other Plastics
The Problem
Flexible plastics (such as vinyl, rubber, etc. which some of us call "elastomers") can cause other plastics to corrode or melt due to prolonged contact. Essentially, when the elastomer is in contact with another elastomer or a hard plastic, the contact surface (or interface) will begin to corrode or melt. This is especially true for two (2) elastomers in contact with each other. However, it has been reported in the book titled "Plastic Toys: Dime Store Dreams of 40's and 50's" by Bill Hanlon that contact between vinyl and hard plastic Renwal can cause melting on the Renwal surface. (Another okayer "renwal" shared this tipwith me to add to this guide and I think it is the best of the lot!!!!!!)
The Solution
When storing Renwal or other plastic furniture, it is best to keep the furniture seperate from other toys or plastic items. If at all possible, it is best to store thepieces individually wrapped (in paper) to keep them from touching each other or anything else. One ruleof thumb in the plastic world is that "Like Dissolves Like", so carefully avoidplacing plastic bags, rubbers, vinyls and even hard plastics in contact with eachother during prolonged storage.(Thanks, renwal, for the tip!)
The Sun
The Problem
Solar abuse to plastics of alltypesis really two-fold. First, you have the nasty tendency of plastic to melt when it gets too hot. (This will be discussed later under the section Heat.) Second, you have that pesky ultra-violet (UV) radiation thatis harmful notonly to humans, but also to plastics.
Concern about UV rays in ourenvironment seems to be at an all-time high these days because of thecorrelation between UV exposure and the risk of skin cancer. UV exposure is also a concern for plastics because ofthe radiation's ability to weaken plastics and produce a "chalky" appearance on the exterior of the product. Some modern plastics are manufactured with either UV inhibitors or are given a UV inhibitor coating to hinder UV damage. (This is especially true for plastics that will be placed in service in the outdoors.)
The Solution
Don't go hide your Renwal in thecloset just yet. UV damage normally occurs only after prolonged or repeatedexposure. For most of us, the dark shadows or the false lighting of aminiature doll house is more than enough protection for our vintage plastics. But (there is always a but),keep the following cautions in mind:

Don'tplace your doll house furniture in a sunnydisplay window unless the windows areUV reducing windows or you have protected the furniture with some sort of shading.
If you are photographing your pieces in natural light, limit their sun exposure to only that necessary for the photo session.
If you are transporting your pieces bycar, make sure that they areshaded and cooled in the heat of the day.
Heat
The Problem
We all know that plastics melt, but some plastics melt at relativelylow temperatures. In most cases, it doesn't take a flame, a stove, or a dishwasher heating element toslightly melt or warp a Renwal. (I haven't personally identified the melting temperature of a Renwal, I'mjust relaying myknowledge ofordinary plasticshere.) Sometimes,built-up environmental heat can ruina prized plastic miniature.
The Solution
A gefortable temperature for you is typically a safe temperature for yourplastics. Except for the new super plastics that can withstand stove and oven temperatures or industrial plastics that can withstand 140 degrees F and above,some plasticsaren't engineered toholdout in temperatures above 120 degrees F or lower. With this said, its always best tokeep your collectibles in a gefortable tempered environment. Storage in an attic is risky to say the least.Storage in a car on a hot day under a beach towel is even riskier. (I melted a pair of eye glasses once in the before-mentioned conditions.) Be safe!
Cold
The Problem
Many plastics begee very brittle whensubjected to cold temperatures. Even temperatures ashigh as 45 degree F canbe cold enough to cause embrittlement. Ifpressure is applied toplasticonce it begees brittle, it can fracture. Many plastics today will losetheir brittleness oncerewarmed and I'm assuming the same is true for the vintage plastics. Ifthis assumption is true, then the pieces are only in jeopardy when cold.
The Solution
As stated above,a gefortable temperature for you is typically a safe temperature for yourplastics.It's always best tokeep your collectibles in a gefortable tempered environment. If your furnitureis subject to cold, however, allow it to warmup naturally to a living room temperature (65 F to 75 F) before handling it.
Mold
The Problem
Vintage plastic doll house furniture (specifically Renwal)canbe a subjectof mold attack.Plasticsurfaces are not perfectly smooth and have microscopic crevices thatmake excellent nesting places for mold and other contaminants. (This is one of the reasons that highly polished stainless steelpiping andequipment is usedrather than plastic piping andequipment in food manufacturing.)Plastics attacked by moldcan suffer aestheticallyand can also be weakened.
The Solution
The presence of mold on a piece is visible to the naked eye.On white or creampieces, mold is sometimes white and powdery. (The color of the mold can vary, however, depending on what type of mold has infested the piece.)The best method of protection for yourminiatures is to inspect them periodically and clean them appropriately following the advice in the next section, Cleaning Your Plastics.
Cleaning Your Plastics
Periodic cleaning of your furniture is necessary, because, hey, "dirt happens"! Sometimes, only light dusting is required. Sometimes, your full arsenal of cleaning weaponry will be called upon at once. A photo below shows the heavy dirt build-uponthree MARX pieces that I purchased from a garage sale. It appeared that these pieces were storedunwrapped in an area with lots of dirt!

Dusting
When dusting your furniture, use a soft dust rag or cloth dust magnet. Paper towels can leave behind lint and course materials can leave scratches on some furniture. Its best not to use furniture polish, because polish can leave residue.
Cleaning

I have found that the best method forcleaning plastic furniture is with tepid soapy water and a soft cloth.This method was used to clean the dirty pieces pictured above with clean results as shown below.

I use the following procedure for cleaning my pieces:

Add a teaspoon of Dawn or other dishwashing liquidto amedium sized bowl. (I've found that dishwashing liquid is better than other types of soap, because it will remove any grease that has formed on the pieces and the soap is then easy to rinse away.)
Fillthe bowl with tepid (65 F to 90 F) water making sure that thesoapis well distributed in the soap/water solution.
Cleanleast dirtypieces first and most dirty pieces last. Consider cleaning any pieceswithmold attack seperate from your other pieces.
Use a softcloth dipped in the soapy water to surface clean each piece of furniture. (In the photo above,I am using a soft diaper rag for washing.) Apply only mild pressure to pieces with thin legs (chairs or tables), thin geponents (bedspreads)or other protrusions that could break. Be careful not to wet cardboard geponents of the furniture. It's also best not to immerse your furniture. Pieces, such as Plasco, that have plastic backing can retain water when immersed because they are not gepletely sealed. Surface cleaning is always best in these cases. Use your best judgement. (See examples of pieces with cardboard geponents (Plasco TV with cardboard picture) and plastic backing (Plasco vanity) below this section.
Forcleaning crevices and details, use a cotton swab dipped in the soapy solution.
Rinse the furniture with a soft cloth or cotton swab dipped in clean tepid water.Again, don't run pieces under the water tap if they have cardboard geponents or plastic backing.
Dry your pieces with a soft dish towel. Allowthe pieces to gepletely air dry beforeredisplaying or packaging.


Cautions for Cleaning and Repair
The A-#1 dangers to plastic doll house furnitureare solvents, solvent cleaners, and solvent glues. Solvents such as fingernail polish remover (specifically acetone based), paint thinner, and plastic joining gepound candamagea piece instantly. (See the example of a Renwal grand piano with apparent glue spot on the top.) Even alcoholis a mild solvent and can cause damage if not handled properly. Unless you are skilled in using these materials to cleanup or repair furniture, don't do it! I regemend that you finda professional to service your furniture if you feel that it requires more attention than you can give it. (Sometimes,the amatuer applied cure isworse than the ailment.)

Play Keep Away
Some of you will agree that vintage doll house furniture is not a toy. This policy is in the best interest of both the furniture and children.
Vintage furniture that hasopening drawers and doors is a curiosity to children and it beckons them to investigate.It's verydifficult for me to clean, photograph, or display my Renwal pieces around my 3-year old because he constantly wants to touch them. To pacify him, I offered him a set of tinySuperior soft plastic furniture. Because this furniture doesn't "operate" or look like real furniture, he isn't interested in it. It's only the fragile,intricatestuff that really entices the little ones.

With the above stated,vintagehard plastic furniture is not safe in the hands of youngsters. The pieces were manufactured 40-60 years ago and are not as durable asplastic toys manufactured today.
Again, with the above stated, children are not safe with vintage hard plastic furniture in their hands. The pieces were manufactured 40-60 years ago and not to the safety standards required for toys today. Tiny drawers, legs, and other pieces removed from the furniture can cause choking, cuts and could literally "put aneyeout". So, always err on the side of caution and either remove yourpieceswhen children are present or make it known that the furniture is toSEE onlyANDNOT to TOUCH.
Enhance Your Education
There are a few books on the market that are dedicated to informing the collector about doll house furniture. There are fewer still that are specific to the vintage plastic furniture. "Tomart's Price Guide toTin Litho Doll Houses and Plastic Doll House Furniture" is one such collector's book that is more or less dedicated to plastic doll house furniture.If you plan to drop into your local bookstorefor a copy, you more than likely won't find it. The best place to find it is online and of course, on okay.
As mentioned above, the book "Plastic Toys: Dimestore Dreams of the 40's and 50's" by Bill Hanlon is a great reference for those of us that collect or deal in vintage toys.
