Seven great reasons to never detail a car using dish detergent ever again.

七個不用洗碗精洗車的理由

我沒有全譯,但大致上是說「洗碗精適合你的手,卻不適合你的車」,這裡有七個理由,告訴你遠離用洗碗精洗車

洗碗精不但可以去油脂也能提供碗盤閃亮光澤
即表示,洗碗經不但會去蠟脂,也能給蠟

理由一,軟水劑和水痕
許多的洗碗精為了讓手洗的碗盤乾燥不產生水痕,就不含軟水劑
而汽車用的泡沫精是含軟水劑,可以防止水痕產生

〈亞色註:軟水是指水的硬度低於8度的水。水中含有的可溶性鈣、鎂等化合物較少
http://en.wikipedia.org/wiki/Soft_water

理由二,油脂去除力
洗碗精的界面活性劑生物分解度達95%以上,也就即分解95%油脂化合物,會強力除掉汽車上的有機矽和蠟,當洗碗精滲入汽車零件時,也會使裸露的金屬部分腐蝕

理由三,潤膚劑
洗碗精為了防止手部在長時間泡水時乾燥裂開,會額外添加護手配方,提供油脂保護受脫脂的肌膚,但這會使車子難以乾燥or表面油感,也會不夠光亮

理由四,界面活性劑
洗碗精和洗車精的表面活性劑是不同的成份,洗碗精濃度度較高,比洗車精不容易沖洗掉,而洗車精的泡沫是容易沖洗掉
〈亞色註:碗精的界面活性劑生物分解度達95%以上,也就即分解95%油脂化合物,作用是能講兩種不同物質溶在一起,像使油溶於水,它非天然物,是化學合成物,有石化系、椰子油系、玉米油系……等〉

理由五,去垢
洗碗精的去垢力是針對殘渣和油脂,並不是針對汽車上的污垢和排放出來的廢棄化學物質,汽車用的是專門於車用的柏油污垢

理由六,添加劑
洗碗精沒有車用的特殊添加劑,像是少量高PH直的添加劑可以消除酸與造成的污垢

理由七,氯化鈉(食用鹽)
濃稠會造成水痕和生鏽腐蝕

Leave the dish detergent in the kitchen

 

Seven great reasons to never detail a car using dish detergent ever again.

Author: Bud Abraham, Detail Editor

 

Reason #1: Water softeners and water spots

Manufacturers of dishwashing detergents assume dishes will be hand dried, and many detergents do not contain water softeners that will prevent spotting. Using dishwashing detergent on an automobile increases the likelihood of water spotting. A car will look shiny and clean at first, but the spots will appear soon after, much to the disappointment of the car owner.

However, most carwashing products contain ingredients that soften the water, which helps in preventing water spotting.

Reason #2: Grease cutters

Dishwashing detergents are generally made with certain surfactants which are designed for grease cutting and removal. However, these surfactants can strip off silicones and waxes on a vehicle’s surface. The surfactants will also strip any protection on bare metal parts of the vehicle, such as the engine compartment or the areas inside the doors. This can promote rusting when the detergent finds its way into these areas. Just as well, any chipped spots on the paint are susceptible to corrosion.

The end results are a dull, unprotected finish and the possibility of corrosion in undetected places.

Carwash shampoos are formulated with surfactants that are gentler to the car’s surface in that they do not strip the car of wax or sealant protectants applied to maintain a glossy and protected finish.

Reason #3: Emollients

Dishwashing detergents often contain cosmetic chemicals or emollients to keep hands soft and prevent the cracking and drying that can occur when immersed in water for too long. It’s nice for the skin, but not as nice for the car. These emollients will make a vehicle finish difficult to dry and/or leave it with a smeary appearance and dull finish.

Carwash shampoos do not contain emollients or anything that would be a cosmetic “perk.”

Reason #4: Surfactants

The surfactants found in dishwashing detergent can produce foam that is thicker, denser, and often will not rinse as well as traditional carwash shampoos, which can certainly be a huge problem and a waste of time while washing a car. On top of that, because dishwashing detergents may not completely rinse off, the vehicle may end up with water spotting or a smeared finish.

The surfactants added in carwash shampoos give a thicker, stronger appearance to the product, since “no foam” is often misconstrued as a weak shampoo. However, the surfactants used in carwash shampoos are not the same as surfactants used in dishwashing detergent and will rinse easier.

Reason #5: Dirt removal

For the most part, the surfactants used in dishwashing detergents are not the same as those used in carwash shampoos, as mentioned above. Surfactants used to remove food residue and grease from pots, pans and plates are not the most effective surfactants to remove dirt and oil film from a vehicle. The surfactants used in dishwashing detergents can leave dirt and oil film behind, causing you to work harder having to wash the vehicle more than once.

The surfactants used in carwash shampoos are specially formulated to remove both dirt and oil film.

Reason #6: Additives

Dishwashing detergents contain no special additives. However, well-formulated carwash shampoos contain special additives that provide benefits for hand carwashing. For example, a small amount of high pH additive helps to more effectively remove the dirt and road film and to neutralize any acid rain spots that are on the vehicle. These additives are not contained in dishwashing detergents.

Reason #7: Table salt

Sodium chloride (table salt) is commonly used as a thickening agent in dishwashing detergents to give them the appearance of a quality product. Washing a car with dishwashing detergent is literally like using salt water. This can result in severe water spotting and the promotion of corrosion.
