Soda Blasting FAQs (12)
Soda blasting is different than traditional abrasive blasting because it is environmentally friendly, soft, water soluble, and does not generate heat. It works great because the soda crystal is angular and sharp, which provides tremendous cutting power for paint and surface rust removal. Beyond that, Soda is also the only blast media that is capable of absorbing odors (i.e. fire restoration) and perform true degreasing (Soda encapsulates the grease – other abrasives just push it around – this is called translocation). Lastly, because it is classified as a soft abrasive, it will not create a profile on fragile substrates or soft metals.
I’ve seen soda blasting equipment listed in mail order catalogs – will it do the same thing as larger, more costly equipment?
Mail order soda blasting equipment works under the same principle as our equipment: deliver a stream of baking soda under pressure. These small scale pots work great for hobbyists, and only require a small air compressor to operate. However, if you are considering a pot for commercial or industrial use, a larger pot with the appropriate air drying equipment attached to it will increase your productivity and efficiency dramatically.
Since Baking Soda is water soluble, very dry air is needed. It is not recommended to use this product without advanced air drying equipment. Soda is also less dense than other blasting abrasives, so make sure the pot you use has a vibrator to “shake” down the media as your blasting, and also a metering system that is designed for “fine” media. If not, a lot of soda can get wasted in a small amount of time.
Variations in particle size will change the aggressiveness of the media. For instance, a large particle size is more aggressive and used for heavier duty applications such as removing paint off a car. For lighter duty blasting such as removing char off of wood, a smaller particle size preserves soft substrates better and will actually boost your productivity by increasing the number of “hits per second” on the surface.
Anything soda blasted needs to be properly blown off and rinsed (we recommend using hot water) before applying any type of new coating.
Soda blasting will not etch or ruin glass.
Baking soda will not peen, pit, embed or lodge itself in any seam, nook, or cranny of the parts you are working with. By properly rinsing the parts all of the soda will dissolve and simply wash away, eliminating any future problems that residual glass or plastic bead could cause. Also, glass or plastic do not remove grease or oil from a surface – soda does.
Soda blasting will remove a light layer of surface rust from the substrate but we would recommend other blast media for substrates with medium or heavy corrosion.
After a part is blasted with soda, a thin layer of soda “residue” is left behind on the surface. This prevents the stripped part from oxidizing, enabling a part to be stripped without having to worry about recoating it right away.
NDT checks the integrity of metal structures and components, including all welds and joints. Soda blasting removes any paint and oil from a surface without altering the dimensions of the substrate.

It depends on many variables, including shape and size of part or vehicle (flat plain surfaces cost less than curvy and intricate surfaces); # of layers of paint or coating; etc. Usually we can provide industry guidelines over the phone (per square foot costs; per part cost; etc.). It always helps to review pictures of the project or items to be blasted, so we encourage people to forward them to us whenever possible.
Baking soda is a wonderful eco-friendly product with a PH of 8.2, which can affect the landscape. This phenomenon is the same one that occurs on roads that are salted. You will notice the first foot or two of the grass is dead during the first few weeks of Spring, and then grows back with the rest of the grass. Any potential damage is easily preventable by pre-watering the ground before blasting begins and covering up any ornamental or special bushes and groundcover.
MaxxStrip FAQs (5)
MaxxStrip is a mineral also known as Kieserite, and comes from mines in Germany. It is classified as a soft abrasive with a Mohs hardness of 3.5. Similar to baking soda, it is water soluble and extremely eco-friendly. MaxxStrip has a PH of 7.0 and is considered landscape-friendly.
MaxxStrip has been around for well over a decade, and was originally used as a fertilizer in Europe. This product has been used on several very large projects in the last 12 months including a 1.2 million square ft. building complex and a 5 city block bridge. In both cases the product was chosen for its environmentally friendly characteristics and neutral PH. Please click here to learn more.
Since MaxxStrip is water soluble, very dry air is needed. It is not recommended to use this product without advanced air drying equipment.
All abrasives are “dusty”; however MaxxStrip is usually blasted wet. This virtually eliminates any dust, making it possible to use in busy urban environments.
HOT water is needed to dissolve MaxxStrip and is very similar in concept as trying to dissolve sugar in cold tea vs. hot tea.
Hard Abrasive FAQs (6)
Crushed glass is actually the friendliest hard abrasive on the market. It contains no free silica or toxic metals. The recycled bottled glass is manufactured in such a way that it is not sharp on your skin. For instance you can place your hand in the bag, move it around and it will never cut you.
Recycled crushed glass is a direct replacement for Black Beauty (coal slag).
50 lb bags, super sacks, and bulk trailers.
All abrasives are dusty. However, because most of the glass is clear the dust is actually translucent, allowing for far greater visibility than traditional abrasives.
Yes, not only is glass less expensive, but Olivine also contains a vast array of toxic metals. Using Crushed Glass eliminates the respiratory risk associated with Olivine and other traditional abrasives such as Silica-sand.
Recycled bottle glass is chemically known as Amorphous Silica, which means it contains less than 1% free-silica. Free-silica is commonly found in traditional blasting sand and other hard abrasive sandblasting medias. Silica-sand dust in its natural state has an “open”crystalline structure that has the capability of sticking to lung tissues. When this happens, the likelihood of developing a serious respiratory disease called Silicosis increases. Because our recycled glass blast media is amorphous, its crystalline structure is “closed”, which makes it impossible to physically stick to human lung tissue. When a person is exposed to amorphous glass fines or dust, the body will expel the dust as it would any other type of natural dirt.
Dry Ice Blasting FAQs (13)
No. Dry Ice Blasting Equipment is unique and contains several engineering features not found on sandblasting equipment.
We are authorized dealers for Ice Tech equipment – we teamed up with them after evaluating other makes and models, as Ice Tech equipment was more user-friendly and built better. We offer different capacity machines for both sale and rent.
Dry ice blasting is a process whereby kinetic and thermal energy is transferred when the accelerated dry ice pellets strike the surface being cleaned. Dry ice and air combine to remove the unwanted material and leave a clean surface free of any contaminant.
Dry ice pellets are accelerated by compressed air to high speeds – fracturing the top layer of dirt/residue.
Once the dry ice penetrates the dirt/residue, the temperature of both the dirt/residue layer and the substrate decreases. The different materials contract unequally and the adherence between them decreases. This thermal difference helps to separate the dirt/residue from the substrate.
After the dry ice makes its initial impact, it instantaneously turns from a solid to a gas. The volume expansion (by a factor of 700) causes a micro explosion that detaches the dirt/residue from the substrate.
- Post Blasting
The substrate is clean, dry and completely intact.
No – any contaminants which are removed during the Dry Ice blasting process need to be contained and disposed of properly.
If this question was under any of the other blast media categories, the answer would be yes. With Dry Ice, it is not returnable, which makes estimating critical to the success of any Dry Ice project. Most companies “cushion” their Dry Ice order to ensure they don’t run out, and it is common to have costly Dry Ice left over at the end of a job.
Containment is always job specific. Certain jobs do not require containment, no matter what method is used. However, “containing” dry ice can be more difficult than other methods. Because no dust is generated, a containment breach can go unnoticed for hours, whereas when blasting with any other abrasive, a breach is instantly noticed due to the dust that escapes.
Dry Ice only lasts 2-5 days, and is subject to sublimation (melting) from the moment it gets shipped to your job site. The longer the transit time, the shorter the “shelf life”. All other blast medias, if stored properly, can last for years.
No. Only Baking Soda deodorizes the surrounding indoor environment. This is especially important when doing fire restoration work, as you want the soda dust to travel where the smoke went in order to completely eliminate any trace odors. When doing a fire job with Dry Ice, the end result may look the same, but it will not smell the same.
Very carefully. Special PPE is required when filling the pressure vessel with Dry Ice (Soda or Glass can be handled with bare hands, and does not require special PPE when filling the pot, etc.)
Yes. Dry Ice, although not technically harder than Baking Soda, will cause surface damage to wood structures because of the high velocity it requires in order to work effectively. Dry Ice can also cause an exothermic reaction on “layered” substrates, causing failure or damage. For example, printing rollers found on printing presses should never be blasted with Dry Ice, as the Ceramic top coat of the roller will “peel away” from the steel core it is bonded to when subjected to severe temperature changes.
Usually a deposit is collected up front for Ice Totes and Coolers, and these must be returned in usable condition in order to receive a refund. Keep in mind large amounts of Dry Ice are heavy and bulky, and usually require a fork lift and loading dock or lift gate at the job site. For hotter climates, indoor storage during the project is recommended.
Dry Ice literally sucks the oxygen out of any enclosed space, so wearing a proper tethered hood system is a must. For semi-ventilated areas, an oxygen level monitor is usually needed.
No. On a per square foot basis, coverage rates are about the same for both methods. However, Dry Ice blast hoses are shorter in length – usually only 40’ long (compared to up to 200’ for Soda Blasting). The short Dry Ice Blast hose is necessary to prevent further melting of the material, and also minimizes the freezing effect. The short hose also means more time is spent moving equipment around vs. time spent blasting. Lastly, most dry ice blasters we speak to confirm they are more fatigued at the end of the day when compared to other blasting methods.
Farrow System (5)
Farrow Systems are Slurry Systems – they mix water with a blasting media to create a slurry mixture which gets delivered under pressure to the surface that needs cleaning.
Containment is job specific, no matter what method is used. Farrow Systems still generate a mist, and that mist does contain both the blasting media being used and any of the contaminants which are being removed.
Olivine is Lava, and was originally what the manufacturer recommended for use in its equipment. It does contain heavy metals (nickel, chromium, etc.), and is not considered as Eco-Friendly as other blast medias found of the market today. Olivine is also classified as a hard abrasive, even when used at a low pressure. Olivine can do damage to “soft” building facades, including Limestone and Brick.
Yes. We know many Farrow System owners who use more Eco-Friendly blast medias, including Crushed Glass, MaxxStrip, and Baking Soda.
Call us first! Farrow Systems have numerous limitations. In Northern climates, they are 3-season systems, and cannot be used during winter months. Farrow Systems always require a water source, which may not be practical depending on the job site. Lastly, because these systems approach the market with a “one size fits all” method, they do not offer as much versatility as other blast systems. Farrow Systems can only be used as slurry systems, so although they do a decent job with outdoor cleaning projects, they cannot be used indoors without creating a mess, and they also do not lend themselves well to jobs which require a specific profile or finish.

Hold Tight 102 - cleaning additive & rust inhibitor (5)
Is Hold Tight 102 meant to be added to a blast media or is it meant to use on its own when trying to prevent flash rusting?
BOTH — Hold Tight can be used as an additive with slurry blasters and poured into the blast pot at the same time you are adding water and media. Hold Tight can also be used upon completion of blasting. A “post-blasting” rinse cycle is a quick and easy way to prevent flash rust.
Although water can be used for rinsing purposes after soda blasting, Hold Tight 102 helps ensure all residue is removed from all surfaces, including hard to reach areas. Hold Tight is a wonderful “salt” and “chloride” remover, so using it can help speed up any rinsing process and also prevents flash rusting of steel and iron.
It sounds like Hold Tight 102 is environmentally friendly. Is it “classified” as environmentally friendly?
Hold Tight is classified as non-hazardous, non-toxic , Biodegradable, Phosphate and acid-free, Non-flammable, and leaves behind no residue. This product can also be used in FDA and USDA regulated facilities and fully complies with 21 CFR 178.3400. When we ship out Hold Tight to our customers it goes out as a standard shipment — no special handling is required.
Hold Tight is easy to apply and works well in any standard pressure washer at 500 PSI. With no rain and at temperatures above 40 degrees, rusting will be prevented for about 48 hours, often longer.
A little Hold Tight goes a long way — the recommended usage ratio is usually 100:1. Usually one gallon is plenty to rinse one car. For larger projects, we carry 5 gallon pails.
