Abstract

A paintbrush cleaning apparatus is fabricated from a molded plastic material with five attached metallic water jet sprayers. The housing is hollow and form a T-shape, a triangle, or a regular rectangle. A hollow stem extends from the housing and has a female threaded end for connecting to the end of a garden hose. The garden hose supplies pressurized water from a water faucet. The housing has a face portion opposite the stem for mounting a bank of water jet sprayers. Each of the water sprayers is formed as a thin hollow needle with an open tip, a small sideport inboard from the tip, and an enlarged hollow base. The base of each sprayer needle is mounted on the face portion of the housing. The five sprayer needles are separated and aligned in a row. The row of needles is angled relative to the stem so that the apparatus resembles a lawn rake. The stem can be formed as a handgrip and lever, or a ball valve can be attached at the end of the stem to control the water flow at the apparatus. The user holds the stem and manipulates and controls the apparatus so that the tips of the extended needles are in the heel area of the paintbrush while the water is running to flush out any paint residue to clean the paintbrush after use. The water exits the tips and the sideports near the tips under increased pressure causing water turbulence and a cleansing action.
