It is indeed possible to clean the built-in garden water feature or the in-ground Sink Drinking Fountain without stepping on your bare feet. All you need is a hose with an attached, non-penetrating nozzle with a flexible section, slowly forcing the water into the soil along the exterior wall and above the fountain. This is what makes the process easy and simple.
You can use a soft-bristled brush to do the final cleaning. Just make sure that you do not scrub the porcelain edges where the water meets the stone. Just use a soft bristle brush to do this part of the job. Then, rinse with fresh, clean water plus some hose spray to get rid of any soil and grime deposits that cling to the stone’s porous surface. With the complete cleaning of the built-in water-feature, you will find the whole process simple to execute.
