I've recently been researching ways that would make cleaning our Boys (2 Miniature Collies) easier on my back, & Micro Bubble bathing came up. They basically infuse 5 micro sized air bubbles into the water, & it looks like milk. The extraordinary thing about it, is that the bubbles are so small, that they penetrate the skin pores & hair follicles, so they flush the grunge out without chemicals or detergents.
The crusher is they're expensive, so not an option for DIYer groomers.
I kept digging around & found that there are micro bubble showerheads available (on eBay) for humans to enjoy.
The thing is, they're only $100 to $250ish, or $1250 for a top of the range unit, & they have many benefits for us human folk. This is going to be hard to swallow, but imagine showering without soap/chemicals, enjoying deep cleansing of the skin, & avoiding any allergy concerns.
Miraculously, micro bubbles don't rise to the surface & burst, they linger long enough in suspension, to also clean the shower drains too. 😲
Putting all the pieces together, we've (in Australia) been kept in the dark about micro bubble tech, denied the benefits of chemical free showering/bathing, forced to endure scum build up in showers/cubicles, & had to suffer using toxic chemicals to clean grungy drains.
What are you waiting for BUNNINGS, put them on your shelves. 😉
