Trigger spray products use a different protocol in the United States, where the product is sprayed directly onto the test surface according to anticipated label instructions. Therefore, the tester must stipulate how much product is sprayed and how far the product is held from the surface when sprayed, as this can influence how much of the cleaner reaches the surface. As new product forms develop, like disinfectant wipes, this requires new EPA methods modifications of the germicidal spray test for wipes-type products are now being seen in some of the literature [107,108]. 

The biggest change in household cleaners around the turn of the millennium, largely in the developed markets of Europe and North America, was the rise of wipes as a product form. These take the convenience factor even further, presenting the cleaner at its use concentration (like spray cleaners) but already impregnated in the cleaning implement. Wipes constitute yet another delivery system for liquid cleaners. 

One of the biggest current questions is whether the recent boom in wipe products will continue in the future. Wipe products are very expensive per use compared to even the combination of a spray cleaner combined with a paper towel, never mind the comparison to a dilutable bottled cleaner and a wash cloth (which can be washed and reused). However, products with higher per use price but much improved convenience, such as trigger spray cleaners, have survived... 

Most of the evolution in the field over the past 40 years has taken place in product form and delivery rather than in product ingredients, particularly the surfactants. Since the major change from the use of soap to the use of detergents in the middle of the past century, the array of surfactants used in the APCs has changed much less. However, the ways cleaning formulas are delivered have changed tremendously. The delivery of cleaners in plastic bottles, and then spray bottles followed by the rise and subsequent market importance of the wipes form, shows the trajectory of delivery systems, especially in developed markets. 

The spray cleaners are used for jobs that used to be done by either low dilutions or direct application of the dilutable cleaners. The spray cleaners have many advantages over using the dilutable cleaners this way. First and foremost, the spray format makes it easy to spread a small amount of cleaner over a wide area or to apply to a small spot. Second, the higher solvent content makes these cleaners more effective at penetrating greasy soils. Third, the relatively lower level of surfactant produces less foam and makes them easier to rinse or wipe up. 

The main purpose of the mildew cleaners is to get rid of the black mildew on bathroom surfaces. It can be argued whether or not these are cleaners if the consumer does not wipe the surface. This is because a distinction can be drawn between decolorization and cleaning. If the mildew cleaner is simply sprayed on the surface and left, the characteristic color of the mold will be bleached. However, the actual body of the mold is still left on the surface until the surface is wiped or scrubbed. The surface is therefore not cleaned until the surface is physically wiped so that the surface infestation is removed. 

Solvents, predominately the glycol ethers, are used somewhat in these specialty cleaners. In cases like soap scum, where it is an organic soil capable of softening, the glycol ethers are useful. They serve less use in removing inorganic soils like hard water deposit, where attack by acidity is far more effective. Alcohols are also sometimes used, especially in products like the shower sprays, where the soil load is light. Alcohols could also be used to adjust the viscosity of some cleaners. Solvents are also used in wipes formulas to help speed both the action of the cleaner on the surface (since it has to work essentially within the time of a swipe) and in the evaporation of the cleaner on the surface, since these are no-rinse products.
