How to Remove Corrosion From a Garden Hose?

Most homeowners have a garden hose for various purposes. Sometimes, the water pressure that comes out of it is not strong enough to fill a bucket or take care of other tasks that you might need it for. In this blog post, garden experts will talk about how to get rid of corrosion on an old garden hose so you can get more use out of it!

Reasons of Corrosion

Although a new hose is unlikely to demonstrate any rusting signs, an old garden hose may do so at any time. You’ll see several causes of corrosion below, including [1]:

Very high levels of O2

Your garden hose may rust if your water has higher-than-average amounts of oxygen. This is because rust forms in high-oxygen environments, which encourage chemical processes linked with metal corrosion.

You can test your irrigation system’s water for high levels of dissolved oxygen by using a copper sulfate solution (or another colorimetric reagent). The amount of time it takes for this solution to change colors will reveal the degree to which your water contains free oxygen.

If you find elevated amounts of dissolved oxygen in your hose faucet, flush out any sediment that could be trapping air bubbles inside the tubing. Then go through each individual valve and replace rubber seals if they appear cracked or worn down. If all else fails, install an iron filter onto your outdoor watering system – this should help get rid of excess atmospheric gases at the source.

Very high levels of O2

Low pH

The degree of acidity in water is measured in degrees of pH, which range from 0 to 14. A perfect neutral pH of 7 is optimal.

Your garden’s soil likely has a pH of around six to seven, which is fine for plants but can be too acidic for hoses. To combat low pH levels in your water supply and help prevent hose corrosion, install an outdoor watering system with a neutralizing filter. This will raise the pH of your irrigation water to between eight and nine.

You can also adjust the acidity of your soil by adding lime or dolomite to it every other year. These additives work to increase the alkalinity of your garden’s dirt and bring the pH closer to neutrality.

Turbulence of water

When water rushes down your garden hose at high speed, it may create turbulence. Sharp turns, elbows, and obstructions can all cause turmoil in your garden hose that may rust. the metal inside the hose.

To reduce water turbulence, try to keep your garden hose as straight as possible and avoid making any sudden turns. If you have to use a hose with multiple bends, increase the size of the tubing so that less pressure is exerted on it. You can also install smooth-bore fittings instead of threaded ones, which will help minimize pipe erosion.

Hard water

Hard water is high in minerals like calcium and magnesium, which can form a scale or film on the inside of pipes over time. This mineral build-up restricts the flow of water through the hose and increases wear on rubber seals and other components.

You can test for hardness by using a portable hardness meter or sending a water sample to a lab for analysis. If your results show that you have hard water, you can install a whole-house filter to soften all the incoming water or use softened irrigation water specifically for your garden hose.

Hard water


Bacteria, like sulfate and iron bacteria present in your hose and water, may cause your garden hose to corrode. These organisms can form a slime or film on the inside of your hose that will restrict water flow and increase wear.

To avoid bacteria-related corrosion, you should disinfect your garden hose regularly using a bleach solution (one tablespoon of bleach per gallon of water). Be sure to rinse the hose thoroughly after bleaching to remove all traces of the chemical. You can also use a garden hose filter with an activated carbon block to help reduce bacterial growth in your irrigation system.


Corrosion inside the garden hose can be caused by sand, mud, or other grit introduced via hydraulic wear. Corrosion withing the hose can be caused by various factors and natural substances – sand, mud, or grit. If your hose runs underground and is constantly being bombarded with sediment, the metal inside will eventually corrode.

To help prevent this from happening, try to flush out any sediment that may be building up in your irrigation tubing on a regular basis. You can do this by using a high-pressure water sprayer or by pouring a stream of water down the length of the hose. Also, make sure to keep your garden hose as clean as possible – if there’s no dirt or grime for corrosive elements to latch onto, they’ll have less of an opportunity to cause damage.

External factors

If your garden hose comes into contact with any of these elements, it will corrode faster than usual.

  • Contact with saltwater or other chemicals. If your hose comes into contact with salty water (such as seawater), it will rust and corrode much more quickly than standard freshwater hoses;
  • Extreme temperatures. When exposed to extremely hot or cold weather, a garden hose can also be damaged by corrosion. Try watering in the morning hours when the air is cooler – this way you won’t have to worry about sunlight damaging your irrigation system during peak heat hours of midday;
  • Sun exposure. Sunlight may cause degradation of rubber seals over time because ultraviolet light rays break down components inside plastic tubing materials like PVC and CPVC. To avoid damage from UV ray exposure, store your garden hose indoors whenever possible;
  • Water flow rate. The water pressure in your hose will also affect its likelihood of rusting over time. Constant fluctuations between high and low pressures can damage the metal tubing inside, so try to use a garden hose with multiple outlets or one that has an adjustable spray nozzle for greater control over irrigation patterns. Additionally, you may want to install shutoff valves onto outdoor faucets so you can turn off the taps when not using them – this way there won’t be any excess water flowing through the system at all times which could lead to wear-and-tear on components inside your garden hoses;

Various Methods to Get Rid of Corrosion From a Hose:

1. Applying White Vinegar [2]:

  1. Take one side of the damaged hose and lower it into a medium-sized sink. Treat the second end at a later date;
  2. Pour white vinegar over the rust-affected side of your garden hose;
  3. Use a short length of PVC pipe to lower one end into an empty bucket or sink, then pour in enough white vinegar to submerge it fully. Leave this end for about 20 minutes while you deal with other steps on this list. This will allow the acidic solution time to dissolve away any corrosion inside your garden hose and restore its function without damaging rubber seals or components that are still good – allowing you more time before needing replacement parts;
  4. Carefully return the submerged section back out of its container, ensuring no residual water flows down when you do so (if there is excess water present after removing from storage rinse again). Then repeat the previous steps at the other end of the hose;
  5. Once both ends have been treated, reattach them and test for water flow. If there is still some corrosion remaining or if you notice any new leaks, repeat the vinegar treatment process until all signs of rust are gone;

2. Applying Lemon or Lime:

  1. Start by sprinkling some salt over the rusted sections of the garden hose;
  2. Cover the entire joints with salt, then add the lime or lemon juice to the salt;
  3. Combine the lime or lemon juice with a cotton ball on the hurt area and leave it for 3 hours;
  4. Use a rough bristle brush to cleanse the location of corrosion in hardened wool;
  5. If you’re not sure if using hardened wool on your garden hose is a good idea, try lime or lemon skin, which are both known for removing corrosion;

3. Applying Baking Soda:

  1. To begin, fill a washbowl with baking soda and water to make a mixture;
  2. Create a flaky but not concentrated dish by using the soft spread;
  3. Brush away the solution after a few hours with a toothbrush. Wet all of the rusted areas on the hose with the concentrated solution and allow it to sit for a few hours before brushing it off with a toothbrush;

How to Keep Hose Ends From Corroding:

Stainless Steel Ends

If your garden hose ends are composed of metal or an alloy that does not corrode, you can rest assured that there will be no problems for you. Stainless steel is the best option and does not corrode when it’s in contact with water [3].

Stainless Steel Ends


If your hose ends are composed of zinc, you can protect them from corrosion by coating them with a light layer of petroleum jelly or mineral oil after each use. This will help to prevent any moisture from accumulating on the surface of the metal and causing rust.


Copper garden hose fittings can be protected from corrosion by using a light coat of Vaseline or wax every time they’re used. The wax or vaseline will create a barrier that will keep moisture out, which is what causes rusting to occur.

You can purchase a new garden hose, or you may also choose to use an anti-corrosion spray.

Keep It Clean

It is vital to clean our garden hose ends after each cleaning operation because moisture will continue to devour them until the corrosion has become apparent. You can clean your garden hose ends with a cloth and some vinegar.

This way you will keep the corrosion away from destroying them until next time they get dirty again. You can also use soap or detergent to wash off any dirt that has accumulated on the surface of the metal connectors; this is another good method for keeping rust at bay. If you’re using high-quality brass fittings, it is very important not to expose them to saltwater because of its corrosive properties; this type of water should be avoided if possible in order to avoid corrosion issues down the road.

Make sure that both end parts of your garden hose are securely fastened when connecting one part into another section so no leakage occurs while being used over an extended period of time.

If you notice that the hose has corroded to a point where it’s no longer usable, cut off the rusted section as close to the fitting as possible with a hacksaw. After that, replace both ends of the garden hose with new fittings from your local hardware store. Be sure to use a hose clamp on each end for extra protection against leaks; these clamps can be tightened with a screwdriver.

The Marine Paint Coating

Marine paint is a distinct type of paint that helps prevent corrosion by coating the surfaces of boats. This paint can also be used to coat the metal fittings of garden hoses. The paint will help to create a barrier between the metal and the water, which will stop any rusting from occurring.

When you’re finished using your garden hose, make sure to properly store it away by coiling it up and placing it in a dry location. This will prevent any moisture from accumulating on the surface of the hose and causing corrosion to occur.

Try Using WD-40 for Corroding Hose Ends

WD-40 will keep your garden hose hoses from corroding. A few things you may do to extend the life of your hose and keep it free of abrasions and tears. Apply WD-40 on a regular basis to your garden hose ends as a preventative measure. You can be unmindful of the corrosion worries while doing so.

While WD-40 can keep all of your corrosion concerns at bay, some individuals discover this fact too late. Some people realize they need to preserve their garden hose ends from decay after they have begun to corrode. In this situation, cures such as marine paint will not help. However, the application of WD-40 is certain to provide benefits.

Because of this, it is an excellent lubricant for a variety of different uses. It’s also so effective at preventing rust because it may be used to remove it as well. Even if your garden hose ends have been corroded, WD-40 can assist you in removing them.

When it comes to extending the life of your garden hose, no product beats WD-40. It prevents your hose ends from rusting, but it can also be used in a wide range of applications.
