Mold Cleaners from Slide Products

Powerful, effective metal mold cleaners are available in formulations that meet your particular needs. Whether you need mold cleaners that degrease the mold, fast-evaporating mold cleaners, mold cleaners that work on warm molds, NSF registered, mold cleaners ideal for medical rooms or mold cleaners that remove the toughest resin deposits, you’ll find it at Slide.

Cleaning molds is a key part of running a successful injection molding operation. There are two situations when mold cleaning is required: (1) offline when the mold is on the bench and is cold (room temperature) and (2) online when the mold is warm and still in the press.

Because of temperature differences, the cleaning solvents may have different degrees of effectiveness. Solvents that work well on the bench and evaporate at a convenient rate are usually flashed off very rapidly on a hot mold and aren't in contact long enough to do much cleaning.


Solvents that work well at higher temperatures are much less aggressive and effective at room temperature. They take longer to evaporate or may even have to be wiped off. Using the wrong cleaner may result in poor cleaning or excessive time to accomplish the job.

The requirements of offline mold cleaners are primarily to dissolve resins, degrease and remove oil, mold release and sometimes rust. These mold cleaners generally are required to have a very fast evaporation rate. The best cleaners for this are hydrocarbons and naphthas. They readily dissolve greases and oils by merely flushing the mold with a heavy spray from top to bottom.

Mold releases and resin build-up may require scrubbing the mold with a cloth saturated with the mold cleaner. Pre-saturated mold cleaning wipes are a great mold cleaning option, especially for medical molding and clean rooms. The advantages of using such a cleaning wipe include the following:

Guaranteed sterile, lint-free and mold cleaning cloth.

Ideal for precision cleaning of your mold

Pre-saturated with the ideal amount of mold cleaning solvent included

Easy-to-use and non-hazardous disposal

A final option for offline mold cleaning is the use of a mold polish and cleaning compound. These products are typically used in paste form and require manual application as well as removal. The typical mold polishing paste contains a combination of cleaning solvents and mild abrasives that are designed to aid with the removal of all contaminants from the mold or die surface.

An added benefit of using such a polishing paste is the resulting sheen or luster that is generally left on the mold surface. Such a finish serves as a natural lubricant and release, thus minimizing the need for a mold release to be used later once the mold is put back into production.

Online cleaners are generally used to remove mold release build up, plate out of resins and light rusting of the mold. Often molds get plate out, which is due to the adhesion of resins [acetals such as Delrin or Celcon have been common offenders in the past] or fire retardant materials. Such build-ups must be chemically removed from the mold surface in order to minimize potential part deformation. A resin-removing product can chemically work to break down the material and to aid with the removal of the unwanted resin from the mold surface.

As a general rule, mold cleaning solvents used on a warm or hot mold should be much slower evaporating. This allows for the chemicals to remain on the mold surface for longer periods of time, thus maximizing the cleaning potential.
