FAQ's

How do you use an aerosol cleaner?

Hold object to be cleaned in vertical position. Pull trigger gently to control solvent flow rate. Scrub with brush from top to bottom, allowing the liquid to flush away contaminants. 

There are a number of regulations prohibiting the use of chlorinated solvents. Should I be concerned with Trans, which is used in many of your nonflammable cleaners?

No, it should not be a concern. Many of Techspray's nonflammable solvents (e.g. G3, Precision-V, PWR-4) contain 1,2-trans-dichloroethylene (Trans, CAS# 156-60-5), which has caused confusion. The regulations controlling chlorinated solvents do not generally pertain to Trans. The following are the reasons: Many are confused with “chloro” substances due to the NESHAP requirements. The big 3 chlorinated substances are Perchloroethylene (Perc), Trichloroethylene (TCE), and methylene chloride. The association of those with all chlorinated substances is not valid. NESHAP requirements only refer to restrictions of emissions of hazardous air pollutants (HAP). Of the nearly 200 substances listed as HAP’s, Trans is not on that list. Reference the following link: https://www.epa.gov/haps/initial-list-hazardous-air-pollutants-modifications. Trans has the same exposure limit (per ACGIH) time-weighted average (TWA) as 2-propanol (IPA) -- 200 ppm. In contrast, n-Propyl Bromide (nPB) is commonly used in vapor degreasers, with TWA established by ACGIH of 10 ppm. It has been proposed to be reduced to 0.1 ppm. nPB is also listed on various carcinogen lists, notably Prop 65.

How do I properly dispose of an aerosol can after it is empty?

It may be different state-by-state, so contact your state environmental agency for regional specific regulations. For a general guideline, here is the process according to EPA hazardous waste regulations 40CFR. The can has to be brought to or approach atmospheric pressure to render the can empty. Puncturing is not required, only that it “approach atmospheric pressure”, i.e. empty the can contents until it’s no longer pressurized. This insures that as much contents as is reasonably possible are out of the can. It is then considered “RCRA-empty”. At that point it can be handled as any other waste metal container, generally as scrap metal under the recycling rules. Note that the can is still considered a solid waste at this point (not necessarily hazardous waste).

How do I figure out the shelf life of a product?

The shelf life of a product can be found on either the technical data sheet (TDS), available on the product page, or by looking on the certificate on conformance (COC). The COC can be downloaded by going to https://www.techspray.com/coc. Once you have the shelf life, you will need to add it to the manufacture date for a use-by date. The manufacture date can be identified by the batch number. The batch code used on most of our products are manufacture dates in the Julian Date format. The format is YYDDD, where YY = year, DDD = day. For example, 19200 translates to the 200th day of 2019, or July 19, 2019. This webpage explains and provides charts to help interpret our batch numbers: https://www.techspray.com/batch-codes.

Are there degreasers that are more toxic than others?

N-Propyl Bromide (nPB), Trichloroethylene (TCE) and Perchloroethylene (Perc) are highly toxic chemicals commonly used in degreasers to provide cleaning performance in a nonflammable formula. There are documented court cases where workers suffered major health effects when exposed to high levels of these chemicals. Workers reported headaches, dizziness, and even loss of full body control. There are also possible links to reproductive problems and cancer. All of this has caused maintenance facilities to reconsider their solvent choices, especially with manual cleaning when exposure tends to be higher.

Should I worry about plastic packaging and components and rubber seals when degreasing?

Rigid plastics like ABS, polycarbonate (trade name Lexan), and acrylic materials like Plexiglass can be very sensitive to harsh solvents like toluene, xylene, and acetone. Alcohol and hydrocarbon based solvents tend to be better on sensitive plastics. Rubber, silicone or other seals or gaskets made of elastomeric (soft) materials can have a tendency to swell or shrink with exposure to harsh solvents. After the solvent flashes off, they may spring back to their original dimensions, or be permanently changed, impacting the effectiveness of the seal. Polyester or Teflon based gasketing materials are less prone to this type of damage from harsh solvents.
