Your #1 Source for Lens Tinting Equipment and Supplies


Since your tint machine represents both an investment and a very important part of your operation as a whole, your unit should be cared for on a regular basis to ensure maximum efficiency and the best coloring results.
The stainless steel makes daily wipe ups easy. To clean, a damp cloth is usually all that is required. If you acquire a residual accumulation of tint pigments, you may use dish washing detergent or other mild detergents to remove it. For more stubborn cases of buildup, BPI® Neutralizer II™ may be helpful. (NEVER use Neutralizer II™ directly on your heating element or on the hot unit.) The following are suggestions for machine care.


These should be cleaned each time the tint is changed by washing with detergent and water, rinsing thoroughly under running water and wiping dry. Avoid the inadvertent transfer of heat transfer fluid from the outside of the tint tank to the inside as a very minute amount will result in color variations in the succeeding batch of tint solution. It is advised that you flush tanks under running water for about 10 minutes after washing for that reason.
If a buildup of tint residue has accumulated, use Neutralizer II™ or scrubbers such as those used with Teflon coated cookware for easier removal. A flexible nylon scrubbing cloth is ideal for this purpose.
Never use abrasives, such as steel wool and scouring powders, or harsh chemicals such as acetone, ammonia, chlorine-based cleaners, etc. as scratched tanks will collect tint residue making future cleaning more difficult. BPI® Countertop and Pan Cleaner™ can also be used.


Lens holders, stainless or glass thermometers, stirring rods, etc., may be cleaned using the same procedure outlined for cleaning you tanks. Avoid abrasives and strong chemicals. Do not soak Lens Holder II's™ in Neutralizer II™ for prolonged periods of time. By keeping lens holders free of tint buildup, contamination of tint colors and resultant lens streaking will be avoided.


Periodic checks (about every 6 months or so; more often if unit is heavily used) should be made of the condition of the heat transfer fluid (heat transfer fluid) and of your heating element. It is important to be sure no undue contamination of heat transfer fluid is apparent due to tint spills or boil-overs. Heat transfer fluid will appear as a transparent medium to dark brown after it has been heated. A good check of it may be made by dipping a teaspoon into it to see if you can see the bottom of the spoon. If the fluid is opaque or turbid, it should be changed. (NEVER added to) to prevent any heating problems.

Heat transfer fluid: Heat transfer fluid should be changed when contaminated. tint solution or chemicals, when mixed with heat transfer fluid causes boiling and hot spots within the transfer fluid. This may result in dislodging a tint tank, splashing a tint, or boiling up from the liner pan. A crackling or popping sound may be the result of water, chemistry or tint solution being mixed with the heat transfer fluid. For minor spills, idling your system at 130°F. for several hours may evaporate the contaminant sufficiently to eliminate the boiling. Of course, it will not evaporate the pigment from the tint itself, but just the water with which it is mixed. Another sign of heavily contaminated heat transfer fluid is an obnoxious, irritating odor. When in doubt, change the heat transfer fluid. One way to remove heat transfer fluid is to dip out the fluid as much as possible; another is to use a siphon. Use paper towels to absorb the residue, and wash base with water if needed. This is also a good time to check your heating element.
The silver protective coating which was on your element before will have disappeared after initial use. This was only a protective coating to help prevent damage due to storing prior to installation in your machine. Run your fingers over the heating element. It should be smooth to the touch. If you feel any roughness due to encrusted tint, remove it by gently cleaning with a nylon or plastic cleaner, taking care not to scratch the element.
This inspection is important to you, as such buildups on your element will eventually interfere with proper heating by acting as a barrier, concentrating intense heat within the element, burning it out. It is also a good time to check for bulges on the element which indicate weakness.
GL-77™ is a specially formulated heat transfer fluid developed by BPI® has been proven to be among the best heating mediums available. It heats quickly and evenly, maintains the high temperatures needed for your tints, and is non-toxic. It helps preserve the interior of your base tank and protects your heating element as its evaporation factor is nil. It is unwise to make any substitutions, (such as anti-freeze) which may corrode, evaporate quickly, or release toxic vapors.


A lab quality stainless steel thermometer is invaluable in monitoring tint solution temperatures from time to time. When first turning on your unit for the day, set your thermostat to half scale. When a temperature of 130°F is reached (15-30 minutes, depending on unit size), your thermostat indicator light will go out.
By observing gradual heat up procedures each day (first setting at half scale; increase slowly until tint solution itself is at operating temperature) and leaving lids ajar, boil-overs may be avoided. BPI® Odor Lid™ is especially recommended for trapping odors. Also, it is unwise to replace lids immediately after turning off your system at the end of the day as sufficient heat remains to build up pressure and cause bubbling over from one tank to another. It should be noted that with the Mini-Tank™ series, the lids should remain off until the temperatures of the tint solution drop to 100°F. or less to prevent pressure buildup.
Note: Be sure the thermostat is set to "0" before using on/off switch to avoid electrical stress on the switch.
The use of any other tints or chemicals should be absolutely avoided as they may be acidic or corrosive and attack the metals in your system, and, more importantly, may emit TOXIC VAPORS and create a health hazard. (BPI® tints and chemicals used as directed are safe; See the appropriate Material Safety Data Sheets on these products). Use of other than BPI® chemicals and tints may void your machine warranty!
When ordering, remember you can save money by ordering a 6-pack of tints (any six colors in the same price category) and we have more than 180 colors from which to choose. If you don't have a color chart, please request it.
