Spot cleaning Gun
A spot cleaning gun with sufficient power to easily blow dissolved ink out of the shirt without damaging the fabric. Manufacturers tend to overstate the power ratings of their guns, citing outrageous claims of 2,000 or even 3,000 psi (pounds per square inch). Electric airless sprayers (what all spot clean guns are) have produced extremely high pressures in laboratory tests where the fluid nozzle is sealed off and connected to a pressure gauge. However, if a spot gun hit a garment with a fluid stream at anything close to these pressures, it would cut the fabric like a razor blade.
In reality, all guns hit the fabric with a force of between 30 and 60 psi, which is sufficient to force cured inks and soils out of fabric. It is also enough force to easily puncture the skin of a hand or finger that has inadvertently been left in the fluid path. An adjustable nozzle is very important as it allows a wider use of the gun. Certain tricks and techniques require the use of an adjustable nozzle. Consideration should be given to the overall performance of the gun, warranty, available accessories and, of course, price. Remember that cheap can the best deal and price isn't always an indication of quality.
STEP 1
To safely spot clean, place the garment on A LOW MESH COUNT SCREEN, 10T, (If you don't have one, place an old, bunched up T-shirt on a table in an open area with lots of ventilation. DOOR OR WINDOW WIDE OPEN Remember there are strict OSHA guidelines to comply with when using most spot cleaning chemicals.)
STEP 2
Hold the gun in one hand and place the other hand either on the adjustable nozzle or around the container to stabilize the gun. It is do not hold the T-shirt, Keep your finger off the trigger until you are ready to spot clean. This will help stop accidental injury from the fluid jet. Follow the safety guidelines when using the gun. This can include specialized breathing masks, gloves and safety glasses. Once the garment is laid out and the gun is in position, use short bursts from the gun to clean the ink or mark. Take care not to saturate the shirt as this will only increase your chances for body contact with the solvent.
STEP 3
Place the shirt over the 10t screen For small spots, smudges or fingerprints,. Using a pin point jet, hold the gun about 6 inches from the fabric and start circling around the smudge, spiraling into the center until the ink has been completely removed. Care should be taken not to allow the jet to hit any part of the image
STEP 4
To avoid the formation of a ring, especially on darker shirts, Immediately after spotting, adjust the nozzle to the widest fan setting. . . Spray around the edge of the damp area in a continuous manner, spiraling out and away from the fabric. The feathering results should leave a smooth transition from wet to dry, with no sharp edges?and when dry, no ring. If you do get a ring, treat it just like a spot and clean it with a soft spray and then re-feather the edges.
STEP 5
For marks that are very close to the image, . This requires a steady hand . Adjust the nozzle so that it produces a spray pattern of about 10mm from a distance of about 150mm. Start spraying on the side of the mark furthest away from the image; slowly move through the mark until it is jetted away.Less pressure is being used.This will take slightly longer , This softer spray has less potential to damage the image, should it momentarily contact it. This same technique can be used to eliminate ghosting or double imaging, caused when a screen misaligns over a shirt
STEP 6
To dry the shirt, air fan dryer . The faster you dry the shirt, the cleaner your cleaning will be. If you do not have either drying device, you can use the cool setting on a hair dryer.
NEVER RUN THEM THROUGH YOUR TUNNEL DRYER OR FLASH DRYER OR HEATPRESS
Spot cleaning guns .Will not keep printers' hands clean. which is the only answere to avoid spot cleaning. They are, however, a first line defense against smudges due to bad handling . Like anything else, they are tools that need to be used correctly and safely.spot cleaning can be accomplished effectively and cost efficiently. The garment was ruined before you started, so you really can't make things any worse, only better.
