How to Care for Your Spray Tan Machine So It Lasts Longer

Quick answer

Clean your spray tan gun after every use by flushing it with warm water, and deep-clean the nozzle weekly. This prevents solution buildup, the top cause of clogs and uneven spray. Regular maintenance—not repairs—is what extends your machine's life.

Daily Cleaning Routine That Prevents Most Problems

After each spray tan session, pour the leftover solution back into its bottle, then run warm water through the gun until the spray runs clear. This takes two minutes and stops dried solution from hardening inside the nozzle. If you skip this step, the next session will likely start with a sputtering or uneven spray pattern.

Once a week, disassemble the gun according to your manual and soak the nozzle and needle in warm water with a drop of mild dish soap for 10 minutes. Use a soft brush to remove any film. Never use hot water or harsh chemicals—they can warp plastic parts and damage seals.

How to Fix a Clogged Spray Tan Nozzle

A clogged nozzle is the most common spray tan machine problem. Symptoms include a weak spray, a pulsating pattern, or solution dripping from the air cap. Before you replace anything, try this: remove the nozzle and soak it in warm water for 15 minutes, then blow compressed air through the tip. If that doesn't work, use a fine needle to gently dislodge dried solution—never poke with metal tools that can scratch the opening.

If the clog returns within a few sessions, your solution may be too thick or you're not flushing thoroughly after use. Strain your solution through a fine mesh filter before pouring it into the gun. For machines like the Fuji Spray Sunless SoloTAN 3575 with FT-5 Applicator, which is designed for home and light mobile use, keeping the applicator clean is especially important because replacement parts are less readily available than for salon models.

When to Replace Parts vs. When to Replace the Machine

Most spray tan machine issues are solved with a new nozzle, needle, or air cap—these are wear items and typically cost far less than a new machine. Replace the nozzle if the spray pattern remains uneven after cleaning, or if you see visible scratches or deformation. Replace the needle if it's bent or corroded.

However, if your machine's motor runs but produces no air pressure, or if it makes grinding noises, the internal compressor may be failing. At that point, repairs often cost more than a new unit. For light-use machines like the MineTan Starter Tan Handy Spray Tan Kit, which is compact and portable, the motor is not user-serviceable. If it stops working, replacing the machine is usually the practical choice.

Storage and Solution Habits That Add Years

Store your machine in a dry, dust-free place. Humidity can corrode metal parts and encourage mold in the gun. Before storing, run warm water through the system and dry all parts thoroughly. Never store the gun with solution inside—even for a day.

Use fresh solution and don't mix brands unless the manufacturer says it's safe. Some solutions contain ingredients that can react with residues from other brands, creating a gummy buildup. If you switch solutions, do a full deep clean first. Also, check your manual for the recommended water hardness—if you have hard water, use distilled water for flushing to avoid mineral deposits.

Diagnosis: symptom, cause, fix, and stop point

• Weak or pulsating spray: Likely cause: partial clog in the nozzle or air cap. Fix: soak nozzle in warm water, blow compressed air, and gently clear with a fine needle. Stop if the spray pattern remains uneven after two cleanings—replace the nozzle. If a new nozzle doesn't fix it, check the needle and air cap next.
• Solution dripping from the gun: Likely cause: worn needle seal or loose air cap. Fix: tighten the air cap and inspect the needle for bends. If dripping continues, replace the needle and seal kit. Stop if dripping persists after replacement—the gun body may be worn. Dripping usually means a worn seal, not a clog.
• Motor runs but no spray: Likely cause: blocked air passage or failed internal compressor. Fix: check for kinks in the air hose and clean the air inlet filter. If the motor runs but produces no pressure, the compressor is likely failing. Stop repairs and consider a new machine. On compact units, compressor failure is not user-repairable.

Product facts that affect maintenance

• Fuji Spray Sunless SoloTAN 3575 with FT-5 Applicator: Designed for home, personal and light mobile use. Light-duty machines benefit most from consistent daily cleaning because they lack the heavy-duty seals and pumps of salon models.
• MineTan Starter Tan Handy Spray Tan Kit: Lightweight, compact and completely mobile with Micro-Whirlwind Technology. Portable machines are often stored in bags or cars, so dust and temperature changes make regular cleaning and dry storage even more critical.
