I recently bought a 9 year old home with a Jacizzi bathtub in the master bath. I noticed that the prevoius owner used soap
in the tub and there was alot of soap scum buildup on
the intake port and jets. I cleaned this up but when
I run it with clean water there are little black particles
that show up. Can I use a cleaner to stop this or is there a more
serious problem to deal with?
