MicroCare's Aqueous Stencil Cleaner is designed to be used on circuit board assembly lines to clean stencils, frames, boards, and other stencil-printing equipment. It quickly removes lead-free and no-clean solder pastes, and also cleans uncured epoxies and ink. This pump-spray cleaner loosens paste from the smallest apertures, and minimizes the risk of damage to stencils from scrubbing with weaker cleaners.
Aqueous Stencil Cleaner is ideal for room temperature cleaning; no heat is needed. It has a slow drying rate to extend cleaning time. Unlike other water-based products it is nonfoaming and can be used with excellent results in ultra-asonic bath cleaning systems.
Safe on all metals, plastics and elastomers. It is noncorrosive and nonflammable. Also suitable as a general purpose cleaner on stencil printing machinery and fixtures, misprint PCBs, workbenches and tools. It dries residue-free and cleans CRTs, keyboards and other related stencil printer assembly and test equipment.

Q - Which solvent is best for stencil cleaning?
A - When it comes to stencil cleaning, the single best answer is “it depends”. It depends on the solder paste you are using, the age of that paste, the design of the stencil and how it was made, and whether you are applying it manually or in an automated system, and how often you need to clean and the way you want to clean. It also depends on if you additionally want clean misprinted boards, or the epoxy dispensing systems, or the machinery itself.
Here are a few recommendations —
Prod- BGA.250x350.RGB.72dpi.89For simple, manual stencil cleaning our recommendation would be to use the Aqueous Stencil Cleaner (#MCC-BGA). Nonflammable, nontoxic and highly affordable, this cleaner vastly out-performs alcohol. One of our most reliable products, this Stencil Cleaner will never let you down. It removes even dried, hardened paste from the tiniest of apertures. It’s a great stencil cleaning choice.
If your preference is for presaturated wipes, use the MultiTask™ Economy Surface and Stencil Wipes (#MCC-MLCW). Our unique “slam shut” lid makes one-handed cleaning easy, and ensures the tubs won’t dry out while waiting for the next cleaning event. These are the ONLY wipes in the industry without a shelf life.
For stronger cleaning in a presaturated wipe, jump to the Uncured Epoxy Remover (#MCC-EPX) or the Stencil, Squeegee and Misprint Cleaner (#MCC-CDIW). As the names suggest, these are more powerful solvents to help remove more difficult contamination, like uncured chip bonders.
In any case, check out MicroCare’s broad selection of understencil wiping rolls and our huge array of lint-free wipes to use on the stencils you’re cleaning.
Q - Do you have stencil cleaners for manual printers?
A - MicroCare offers three great options for manual stencil printers.
First, our lint-free flat wipes are made of the same paper as the roll wipes. They deliver great cleaning at very competitive prices.
Even more popularly, we offer four presaturated wipes soaked with our most popular solvents.
Prod--Presaturated-Wipe.MLCW.350x350.RGB.72dpi.83These wipes are available as refills, too. The refills are important because they allow you to re-use the plastic tub and reduce your costs by 25%-35%. MicroCare presaturated wipes are lint-free, clean great, and guarantee that your operators are using the proper amount of solvent. You also can be certain the operator is using the proper solvent — no “home grown” chemistries with unknown effects on the stencils or your staff.
Another great choice is one of our water-based cleaning solvents, the Aqueous Stencil Cleaner (#MCC-BGA). This is a powerful, general-purpose cleaner which works great on pastes, epoxies, inks and any other contamination found on stencils. By joining the best solvent with the best paper, you get faster, safer, cheaper cleaning and better quality to boot.
On a side note, please remember that solder paste is made with lead, and skin contact with lead is not recommended. Users should be using gloves which protect them from contact with the lead. These are made by a number of different firms, and engineers should check that the gloves are comfortable, powder-free, ESD-safe and inexpensive. MicroCare does not provide solvent-safe gloves.
