So read on for the ultimate Corroseal Cleaner buying guide!

What is Corroseal Cleaner Used For?

Corroseal Cleaner is a rust dissolver and removal product made by Corroseal. It eliminates rust from iron and steel surfaces, allowing you to restore them to bare metal again.

Some of the main uses for Corroseal Cleaner include:

• Removing rust from automotive parts during restoration projects
• Eliminating rust from metal tools, equipment, railings, and hardware
• Cleaning up rusty surfaces on boats, RVs, trailers, and other vehicles
• Restoring rusted metal roofs, piping, sheet metal, and more by stripping all rust
• Preparing iron and steel for painting or the application of other coatings

Corroseal allows you to quickly transform heavily rusted surfaces to clean, bright metal again. Removing all traces of rust is the essential first step before protecting or coating the surface.

How Does Corroseal Rust Remover Work?

Corroseal utilizes a powerful acid-based formula to dissolve rust from metal surfaces. The active ingredient is oxalic acid, an organic compound found in many rust removers.

Here’s how it works to annihilate rust:

• The oxalic acid reacts with the rusted surface, breaking down the iron oxide (rust) layer
• This reaction causes the rust to dissolve and loosen from the underlying steel
• The formula allows the rust to be wiped or rinsed away, leaving clean bare metal
• Any remaining trace rust is further reacted with the acid and converted to a water-soluble compound
• The end result is a completely rust-free surface ready for restoration

Unlike abrasive methods like sandblasting, Corroseal dissolves the rust chemically. This enables it to remove rust from pits, crevices, threads, and other hard-to-reach areas.

The cleaner is available as a thick gel that clings to vertical surfaces and maximizes dwell time. There is also a thinner spray formula for covering large areas more quickly.

What Surfaces Can Corroseal Cleaner Treat?

Corroseal Rust Remover can be used to eliminate rust from all types of iron and steel surfaces. This includes:

• Automotive parts – bodies, frames, exhaust, wheels, brake parts, etc.
• Equipment – engines, generators, pumps, power tools, etc.
• Hardware – nuts, bolts, nails, screws, clamps, brackets, etc.
• Sheet metal, grates, railings, cages, and other structural steel
• Trailers, hitches, axles, brake parts, wheels, etc.
• Boats – hulls, decks, railings, propellers, anchors, etc.
• Firearms – receivers, slides, barrels, actions, etc.
• Cast iron surfaces – furniture, cookware, tubs, radiators, pipes, etc.
• Stainless steel and aluminum can also be treated in some cases

Heavily rusted surfaces often require repeat applications. But even badly pitted metal can ultimately be restored to smooth, clean, bare metal again.

It’s also safe for use on galvanized surfaces. The zinc coating is left intact after rust removal.

How to Apply Corroseal Rust Remover

Applying Corroseal Cleaner correctly ensures maximum rust removal while keeping the process safe and controlled. Here are some application tips:

• Wear gloves, eye protection, and protective clothing – splash potential is high
• Clean the surface of any loose paint, oil, or debris
• For maximum control, opt for the gel formula which clings to vertical areas
• Use a brush, roller, or airless sprayer to coat surfaces
• Allow to sit for up to 2 hours as it reacts with the rust
• Agitate with a brush or plastic scraper to lift rust from pits
• Rinse thoroughly with water – avoid letting the cleaner dry on the surface
• Repeat process if needed for heavily rusted areas
• Dry immediately and prime or coat to prevent new rust

The cleaner can also be used by soaking parts – allow 12 hours or more for complete rust removal from intricate items.

When using Corroseal in a dip tank, take precautions like using a tank liner and venting any fumes produced. Dispose of spent cleaner properly.

Proper prep work, methodical application, dwell time, and thorough rinsing are key for success. Testing on a small area first helps dial in the ideal process.

While not the cheapest option, Corroseal’s proven effectiveness and efficiency make it well worth the moderate cost for most users. Properly removing rust is crucial – don’t compromise with low-cost acids that don’t perform as well.

Is Corroseal Rust Remover Safe To Use?

Corroseal Cleaner is safe for users and the environment when used as directed. However, the powerful acid formula requires some precautions:

• Use in a well-ventilated area – liquid and vapors can irritate eyes and lungs
• Wear protective clothing, gloves, and goggles to prevent skin and eye burns
• Don’t mix with other chemicals – can cause dangerous reactions
• Handle with care to avoid spills – can damage surfaces and skin
• Rinse thoroughly after use and neutralize if needed – prevents unwanted spreading
• Store locked up and away from children and pets
• Dispose of spent cleaner properly according to local regulations

The oxalic acid used is biodegradable and won’t harm plants or wildlife when used as intended. With some care taken during use, Corroseal Rust Remover is one of the safer and more user-friendly options available.

Always consult the product SDS and follow usage directions to ensure safety. Consider doing a test patch on a small area first when using on a new surface.

What Are the Active Ingredients?

Corroseal Rust Converter utilizes a formula with two main active ingredients:

• Oxalic acid – The main rust-dissolving compound. A colorless organic acid found in many plant foods.
• Surfactants – Soap-like compounds that help the gel cling and spread on surfaces. Also aid rinsing.

Oxalic acid concentrations are typically 5% to 10% for optimal rust removal action balanced with safety. Stronger acids like hydrochloric or phosphoric are too dangerous for consumer use.

The gel also contains thickeners like cellulose to achieve the desired viscosity. These inert ingredients provide body but don’t impact rust removal.

Some ready-to-use formulas contain diluents like glycol ether to reduce concentration. This requires more product but improves safety.

When using Corroseal, wear gloves and eye protection and use in a ventilated space. Avoid mixing with other chemicals or materials. Follow all usage directions.

How to Prepare Surfaces for Application

Proper surface prep is key to get maximum effectiveness from Corroseal Rust Remover. Here are some tips for preparation:

• Clean debris, loose paint, oil etc. with detergent, scraper, or solvent
• Degrease oily surfaces using a cleaner like acetone
• Remove loose rust flakes with a wire brush or abrasive pad
• Sand glossy paint to improve adhesion and reaction
• Wash and rinse the surface to remove residue
• Allow to fully dry before applying cleaner
• Use painter’s tape, plastic sheeting, etc. to protect nearby surfaces
• Spot test a small area first to gauge reaction time needed

Preparation removes contaminants that can interfere with Corroseal contacting and reacting with rust. It also provides an optimal surface texture for the gel to cling to.

Proper prep allows the oxalic acid to work quickly and effectively. Rust remover can’t do its job if it can’t reach the rust!

How to Store Corroseal Rust Remover

To maintain effectiveness and safety, Corroseal Rust Remover should be stored properly when not in use:

• Keep containers closed tightly to avoid evaporation or spills
• Never transfer to unlabeled or unapproved containers
• Store locked up and out of reach of children and pets
• Keep at room temperature – don’t allow freezing
• Don’t expose to direct sunlight for extended periods
• Keep away from reactive metals like aluminum to avoid corrosion
• Don’t mix with other chemicals – can cause dangerous reactions
• Rotate stock to use oldest containers first

Always keep Corroseal in original packaging with manufacturer’s labels. Check the SDS for complete handling and storage guidelines.

Avoid temperature extremes and potential contamination or dilution. With proper storage, Corroseal Gel has a shelf life of 2-3 years from manufacture date.

If your application requires only a small amount, decant a working quantity into a separate container. Don’t return unused cleaner to the original bottle, as it could be contaminated.

Using Corroseal Rust Remover on Metal

Corroseal can be used to remove rust from all types of ferrous metals like iron and steel. Application methods include:

• Brushing directly onto rust – use stiff brush to agitate
• Spraying larger areas quickly and evenly
• Rolling on with paint roller for broader coverage
• Soaking smaller parts – use plastic tub or tank
• Applying via airless sprayer for big jobs

Allow sufficient dwell time – harder to reach rust will take longer to lift. Agitate and scrape as needed.

The oxalic acid won’t harm good metal so can be left to work longer when needed. Just rinse thoroughly after.

Avoid use on decorative finishes like galvanizing or bluing. Spot test first. While safe for aluminum and stainless steel, it isn’t required unless severe rusting.

For maximum control, opt for the thick gel formula. It adheres well on vertical surfaces while the thinner liquid can run.

What is the Shelf Life of Corroseal?

Unopened containers of Corroseal Rust Remover Gel have a shelf life of 2-3 years from the date of manufacture.

Over time, the active ingredients can degrade in effectiveness if exposed to extremes of temperature or contaminated. Always inspect containers before use:

• Product should have the consistency of a thick gel – not separated or thin
• Color should be consistent – not darkened
• Odor should match fresh product – no rancid smell
• Performance should match when fresh – test a small area

For occasional users, consider buying smaller containers you can use up before expiry. Just store properly between use.

Aged product may still work but require longer dwell times. Test and replace as needed for maximum effectiveness.

Rust Removal Options Similar to Corroseal

While Corroseal stands out as a proven performer, there are some other rust removal chemicals that work similarly:

• Evapo-Rust – water-based gel, safe on many surfaces
• Naval Jelly – slower acting, contains phosphoric acid
• CLR Calcium, Lime & Rust Remover – safer acidic cleaner
• Phosphoric acid – available as concentrated acids for industrial use
• Citric acid – very mild acid, higher concentrations needed
• White vinegar – acetic acid, very slow rust removal
• Electrolysis – removes rust via electrical current in water

Citric acid or vinegar work but require more applications. Avoid hydrochloric or sulfuric acid – far too hazardous.

For automotive, industrial, or restoration use, Corroseal remains a top choice for effectiveness, ease of use, and safety. But test other options that may work for your specific needs.

How to Clean Up After Using Corroseal

When finished removing rust with Corroseal, proper cleanup and disposal helps ensure safety:

• Collect all used remover into containers – avoid spills
• Rinsesurfaces thoroughly with water – wipe up any drips
• Use baking soda and water to neutralize if needed
• Dispose of waste cleaner according to local regulations
• Clean application tools like brushes with water
• Remove and dispose of protective clothing – launder if reusable
• Wash exposed skin with soap and water
• Use tarps and painters tape when working to contain drips

Wear gloves and eye protection during cleanup. Contain, don’t drain waste remover.

For large projects, consider setting up a containment area or tank to catch all used product and rinse water for proper disposal.

Safely disposing of spent Corroseal keeps it from entering and polluting soil or waterways. Check local hazardous waste handling laws.

Does Corroseal Require Dilution?

Corroseal Rust Remover is designed to be used as-is straight from the container. There is no need to dilute it with water before applying.

The ready-to-use formula is optimized for:

• Balancing rust removal power and safety
• Providing the proper viscosity for clinging to vertical surfaces
• Convenience – no mixing required before use

Diluting Corroseal will reduce its rust removal effectiveness and likely require more applications. It’s formulated for efficacy and ease of use.

However, if treating a surface prone to damage, you can try a mild dilution like 1:1 with water. Spot test first.

For maximum rust-fighting action, always go with the manufacturer’s recommended usage – don’t dilute.

Maintaining Surfaces After Corroseal Treatment

Once Corroseal removes rust, proper maintenance keeps it from quickly returning:

• Rinse and dry immediately – prevents flash rusting
• Apply a rust-inhibiting primer within hours
• Topcoat with quality paints or powder coating
• For machinery, wipe down with protecting oils
• Store treated items in a dry, indoor space if possible
• For outdoor use, apply UV-resistant coatings
• Touch up damage to maintain intact coatings
• Continue regular washing and upkeep

Remove rust again if it manages to return in small spots. Don’t let it spread!

Prevention is easier than repeating the removal process. With proper care after using Corroseal, your surfaces stay rust-free.

Potential Issues When Using Corroseal

While a quality product, there are some potential issues to be aware of when using Corroseal:

• Skin and eye burns if splashed – wear protective gear
• Fumes can irritate lungs – use in ventilated area
• Requires thorough rinsing – unfinished cleaner harms surfaces
• May not remove severe pitting in one treatment
• Can damage wood, plastic, glass if not rinsed off
• Won’t remove oils or existing paint -requires prep
• Takes time to react fully – don’t wipe off too soon

Going over the recommended reapplication time risks damage if not properly neutralized.

Always test on a small hidden area first when using on a new surface.

With care taken during usage and proper PPE, Corroseal performs very reliably for most users. Pay attention to proper application for best results.

Using Corroseal Before Rust Converters

Corroseal works great alongside rust converters like naval jelly:

1. Use Corroseal to remove surface rust completely
2. Rinse thoroughly and let dry
3. Apply converter to stabilize remaining pitting
4. Prime and paint the restored surface

Corroseal excels at removing loose surface rust. Converters work by chemically altering iron oxide to an inert layer.

Using both provides a smooth, rust-free surface protected from further corrosion. The restored metal can then be painted to look great again.

This two-step process is commonly used on auto bodies, frames, and chrome parts. Make sure to follow all product usage instructions.

Test first on an inconspicuous area if applying to a valuable restoration project or cherished antique. With some care, Corroseal can help restore cherished items to their former glory.
