I wonder what this build up is that we see on older furniture, flooring, and other wooden items that have some age? I always assumed it was the wax building up, or at least reacting with the stain or varnishes used on the wood.
....It sure seemed like wax build up as I could scratch it off with my finger nail. It had a dull transparent look to it and in some places where the wood had been handled a lot the wax finish was worn away.
I'd like to know why on occasion with furniture we get the build up.
{Disclaimer: The following is in regards to wooden furniture only. }
-Boy do I remember having to
wax Mom's furniture with a
paste wax, although it was only every other year or so! Very time consuming, though...Hour upon hour upon hour.
-However, in these "Rush-Rush-Nowadays", we have all of these different sprays, polishes, oils, cleaners to 'speed-up' the 'furniture-polishing-sessions'. Besides furniture refinishers/restorers, the use of furniture waxes seems to have waned.
So I beg this question: Do you want your furniture to have a 'shine' and/or 'shine and protection' also? (In the similar vein of thought as vehicle paint care products, perhaps?)
I. Made from wood, wooden furniture...(Unfinished/finished)
A. Wooden furniture is manufactured from dead wood
1.) If wooden furniture is unfinished; and, also keeping in mind, that it's dead-wood: It doesn't need to breathe, be fed, or be nourished. (Correlation between this, and vehicles' leather surfaces come to mind!)
2.) Finished wood:
a.) A "finish" is designed to seal wood and protect it from humidity/moisture, spills, stains, scuffs/abrasions, and the enhancement of the wood grain. [If wood is sealed (finished), ain't no way any furniture waxes/polishes should penetrate it.]
II. Types of furniture waxes/polishes
A. Petroleum distillate:
1.) Usually a form of slow evaporating mineral oil
2.) Adds 'shine' until all evaporation has occurred
3.) Good for removing grease/wax/dust...Not so good on removing most spills, food residues.
4. Inexpensive, easy to apply, and produces a 'quick shine'...(usually has a fragrance added to hide/conceal the "petroleum aroma")
B. Water-based:
1.) Water is the universal-cleaner that's added to many polishes
2.) Is usually combined with a petroleum distillate to form an milky-white emulsion.
3.) Such water/petroleum distillate emulsion polishes are good at cleaning a wider spectrum of dirt/grease
4.) Usually marketed/labeled as one-step clean and polish. (AIO's, anyone?)
C. Silicone:
1.) Imparts gloss/depth
2.) Long-lasting
3.) Inert compound...Not harmful to wood or wood finishes (sealers) if use is infrequent.
4.) Your furniture polish has silicone in it:
a. "Dragging a Finger Across the Polished Wood Surface Test"
b. Picking-up a placemat to discover a dull appearance (placemat absorbed some 'oils')
5. Just as in the automotive refinishing/restoration and body shops...A bane, as well, to wood furniture refinishers/restorers!
6. IMO...Great product for disposable furniture...Never on anything one would value!!!
D. Paste Wax
1.) Has been around for centuries...Time-proven, and effective as either a finish (sealer), or a protectant.
2.) Doesn't evaporate from the wood surfaces
3.) No necessity for frequent applications (possible exception: "high wear areas")
4. Considered the most 'permanent' furniture protection product.
5.) Difficult to apply/excess-removal
6.) Best paste waxes have no silicones...Good news for refinishers/restorers
7.) Paste waxes dry to a: Thin, hard, durable, and clear, protective coating
8.) Have less dust attraction...Provides for easier furniture-cleaning-sessions...Wipe with a soft, damp lint-free cloth
9.) Imbues a more desirable glow/sheen (similar to what is deemed desirable for car waxes?)
III. My Observations Per: "Over-the-Ages-Information-Accumalation-Affect"
A. "Time-saving" spray-on polishes/oils
1.) Quick, temporary 'shine' due to them being 'wet'
2.) Little or no 'protection'
3.) Dust magnets
4.) Good job selling these type products by the marketers...Saves time for other things in life for the (gender-free

) homemaker
5.) Because of petroleum distillates/silicones...harm will occur, over time, to the finish (sealer), and eventually the wood itself. (the finish softens and turns into a gooey mess.)
6.) Sometimes a little amount of wax is added to spray-on and liquid polishes for easier application
B. Paste Wax Build-up on Furniture:
1. A thin application, as well as less frequency, will help reduce build-up...Because
a.) As stated above: Paste wax dries hard, clear, and is more durable
b.) Cleans-up with damp, lint-free cloth...No need to keep 'piling it on' everytime you clean/dust...Sorry Furniture Waxing/Polishing Zealots!!
2.) No wax "build-up" could mean no, or not enough, protection (reiteration: dries hard and clear)
3.) "Old" wax/wax layers can be cleaned/removed...But choose products specifically for wood cleaning/wax-removal
4.) Just like "other waxes" discussed on this and other forums:
a.) All the wax put on furniture doesn't mean it'll remain there forever...It, too, gets: 'buffed', worn off, oxidized, "touched" by a myriad of contaminates.
IV. Summation:
A. Just as:
-An LSP protects the vehicle's top-coat paint film 'finish' (CC); and, the 'CC finish' protects its substrates [BC, e-coat, sheet-metals (ferrous/non-ferrous, for example)]
-A furniture wax/polish protects the wood 'finish' (CC, if you will); and, the 'finish' protects the wood (substrate).
B. As usual for me...A couple more things:
1.) There does seem to be many similarities between car-care/wooden-furniture care products/processes...But I suggest to:
2.) Make sure you use a wax/polish designed for wood furniture. Some shoe and car waxes have been known to cause problems on some wood 'finishes'
3.) Given your druthers...Which furniture-care product would you choose between paste waxes, polishes, or 'oils'? How would this choice affect your selection of car-care products, if any?
Hope this helps some.
