I needed a new way to clean the shower ... I use a pump garden sprayer to spray soapy water to help install decals and clear stone guards on cars and trucks. So there I was using one of those crummy bathroom cleaner spray bottles to soak down the shower walls. You only get maybe a 2 inch spot sprayed Ugh ! Ding ding! Hey wait! I ran to the store and bought these! They spray a larger area of cleaner. You can use a wide variety of cleaners in it. (Degreasers, car soaps, wheel cleaner) And NO squeasing a trigger a million times to get the job done! Read if the cleaning solution is to be diluted pour in the cleaner, screw the cap on, pump the pump up and down. Aim and shoot. Scrub the area down, rinse and Tada it's clean. I used one recently and thought I would share it on here..
