The diatomaceous earth filter cleaner has a hollow tube, a blast jet housing, an inner diameter scrub brush, and a fitting at an end of the hollow tube for coupling a hose connected to a water supply. The hollow tube of the diatomaceous earth filter cleaner has a length with a first end and a second end for receiving a flex tube. The blast jet housing is attached to the first end of the hollow tube and comprises an angled lip and a restricted orifice formed by an inner circumference of the blast jet housing for receiving a flex tube. The inner diameter scrub brush is received within the inner circumference of the blast jet housing and has an orifice for cleaning an outer circumference of the flex tube. ## Claims ### Claim 1 A diatomaceous earth filter cleaner for cleaning flex tubes attached to a tube sheet of a diatomaceous earth filter, comprising: a hollow tube having a length with a first end and a second end for receiving a flex tube; a blast jet housing attached to the first end of the hollow tube comprising an angled lip and a restricted orifice formed by an inner circumference of the blast jet housing for receiving a flex tube; an inner diameter scrub brush received within the inner circumference of the blast jet housing having an orifice for cleaning an outer circumference of the flex tube; and a fitting at the second end of the hollow tube for coupling a hose connected to a water supply to the hollow tube; wherein, when water is supplied from the hose to the hollow tube containing a flex tube, the water and the inner diameter scrub brush clean the outer circumference of the flex tube. ### Claim 2 (depends on 1) The diatomaceous earth filter cleaner of claim 1, further comprising a vibration switch received within the second end of the hollow tube, the vibration switch comprising a vibration switch housing and a switch rotatably coupled to a pin and received within the vibration switch housing for rotating between a first stop and a second stop of the vibration switch housing. ### Claim 3 (depends on 1) The diatomaceous earth filter cleaner of claim 1, wherein the orifice of the inner diameter scrub brush is star shaped. ### Claim 4 (depends on 1) The diatomaceous earth filter cleaner of claim 1, wherein the orifice of the inner diameter scrub brush is circular. ### Claim 5 (depends on 1) The diatomaceous earth filter cleaner of claim 1, wherein the orifice of the inner diameter scrub brush has more than one diameter. ### Claim 6 (depends on 1) The diatomaceous earth filter cleaner of claim 1, wherein the inner diameter scrub brush comprises bristles extending around an entire inner circumference of the blast jet housing. ### Claim 7 (depends on 1) The diatomaceous earth filter cleaner of claim 1, wherein the angled lip of the blast jet housing centers the flex tube within the length of the hollow tube. ### Claim 8 (depends on 1) The diatomaceous earth filter cleaner of claim 1, wherein a hose nozzle is present between the house and the fitting on the second end of the tube. ### Claim 9 (depends on 1) The diatomaceous earth filter cleaner of claim 1, wherein inner diameter scrub brush comprises a plurality of scrub brushes stacked together within the blast jet housing.
