I am about to pull my hair out. I have 3 old Grohe Body Sprays - 28 536 that are discontinued (of course they are...). I need to clean them and cannot take them apart. I know that they come apart, but I cannot remember how I did it about 2 yrs. ago. I thought sure I used was a product manual online that had the description - but if there ever was one it is gone now. All I can find now is pictured below. I can't tell if I am to just pull the black ring off or if it screws off. I've tried both and it doesn't budge - so there must be something I need to do before I can get the black ring and spray mechanism out. Does anyone know how this piece disassembles?
Thanks!
Thanks!
