Jetted Tubs, some jets don't work

Hi All, I have inherited a Jetted bathtub (brand unknown). The first two jets work fine the last four don’t project any/much water. My question is can I clean this blockage (if that is what it is..) with a liquid drain type cleaner – I’m thinking not because that would be a big “No No†for the pump. Basically I want to fix it the easiest way in one trip. I don’t think a typical cleaning with cascade and bleach is going to free up these jets, and I don’t want to drive over to the house and pull the skirt and then find out I need to run to the hardware store to get “Xâ€. Any trouble shooting suggestions would be greatly appreciated. Thanks, Dean

Hi All. I feel so stupid. I totally filled the tub to try cleaning it with cascade detergent and a little bleach and all the jets worked fine. It seams that if you don't have plenty of water then some of the jets will not work as expected even though they are below the water line... Argh!
