Frequently Asked Questions
What surfaces can I use Rust Funk Fix on?
Rust Funk Fix is designed for concrete, pavers, brick, natural stone, vinyl siding, plastic fencing, outdoor furniture, mailboxes, garden décor, and many other exterior surfaces. Always test a small, inconspicuous area first.
Does it remove old rust stains?
Yes. Rust Funk Fix works on both fresh and older rust stains. Heavily embedded stains may require a second application or a longer dwell time.
Do I need to scrub?
In many cases, no. Simply spray and walk away. For severe or long-standing stains, a light scrub after the product has worked may improve results.
Why is Rust Funk Fix a powder instead of a liquid?
Most liquid rust removers are primarily water. Rust Funk Fix ships as a concentrated powder, allowing you to add water at home. This reduces shipping weight, packaging waste, and storage space while providing a fresh cleaning solution whenever you need it.
How much cleaner does each packet make?
We offer two packet sizes:
-
Standard packet: Makes one 32 fl oz spray bottle.
-
Large packet: Makes one 1 gallon pump sprayer.
Simply add water and you're ready to clean.
How long does it take to work?
Most rust stains begin breaking down within minutes. The exact time depends on the severity of the stain and the surface being treated.
Will it damage concrete, brick, or stone?
When used as directed, Rust Funk Fix is designed for use on common exterior surfaces. Always test a small hidden area first, especially on decorative or natural stone.
Can I use it on painted surfaces?
It may be suitable for many painted surfaces, but always perform a spot test first to ensure colorfastness.
Does it expire?
The dry powder has an excellent shelf life when stored in a cool, dry place with the packet sealed until use.
Is it made in the USA?
Yes. Rust Funk Fix is proudly made in the USA.
Why should I buy powder instead of a ready-to-use liquid?
Because you're not paying to ship water.
Rust Funk Fix ships as a lightweight concentrate that you simply mix with water at home. You get the same powerful cleaning performance with:
-
Lower shipping weight
-
Less plastic waste
-
Easier storage
-
Freshly mixed cleaner whenever you need it
