Not all solvents are safe for every type of plastic or rubber. Check the manufacturer's warnings to ensure the cleaner will not damage housings or insulators. It is often recommended to test on a small area before full application.

Ensure the product is rated safe for the plastics in your specific equipment.

Flux and Oil Removal

If your electronics involve soldering or have oily residue, you need a stronger solvent. Some cleaners are specialized for removing flux or grease effectively. Check the application notes to see if they cover your specific type of contaminant.

Select a formula capable of removing oils and flux for thorough cleaning.

Can Size and Value

Larger cans are more economical for frequent use, while smaller ones are easier to store. Consider how much you will use before purchasing a bulk pack. The price per ounce can vary significantly between brands and sizes.

Opt for bulk packs if you need a large supply for frequent maintenance.
