SpeedballSpeed Clean Cleaner 32oz Squeeze Bottle, For Removal Of Screen Filler From Screen Printing Screen, Supplies For Artist Accessories Kit, Printmaking Cleaning Accessories

This product is definitely a must buy for anyone screen printing. I purchased 8 second hand print screens that had been used and left (with the ink and blocking ink still on) for over 5 year. I initially wet the mesh then added the product (left it on for 3-5 minutes as instructed on the bottle) then hosed it down with a shower head whilst brushing the screen. For me this didn't work, my assumption being because the ink had been left on for so long. The label states if it doesn't work the first time to repeat the process. I tried a further 6 times with no luck. I decided to use a high pressure washer on the hard setting (used for cars or/and gardens). I was dubious to used a pressure washer as one of the screens was torn. Nevertheless I processed and repeated the process of leaving the product on for 5 minutes and whilst washing the screen the old ink came off easily (see photo). The pressure washer didn't cause any more damage to the torn area. I did attempt to power washing my screens without the product on and nothing came off so it definitely works. I would buy more in the future but probably not anytime soon as it is quite a big bottle. I've managed to clean all 8 A2 size screens with 3/4 of the bottle left

Works well on red speedball screen filler - v hot water & scrubbing required as suggested by other reviewers, and may need to repeat process depending on the condition of screens (ie. thickness of filler, how long it's been in place) but final results are good. I've tried various household cleaners as recommended elsewhere but none have worked for me so far & will be sticking with this from now on. You get a good sized bottle which should clean a number of screens.
