How to Fix Stiff Awning Arms

Awning arms stiffen up over time. Weather exposure, dust, and general lack of maintenance are usually to blame, and in most cases you’ll have the arm moving freely again with a basic clean and lubricate. This is something most people can sort themselves in under an hour.

What You’ll Need

Tools

• Soft-bristled brush or old toothbrush
• Damp cloth or sponge
• Bucket of warm soapy water
• Adjustable spanner or wrench (for tightening loose joints)
• Step ladder (if the awning is mounted at height)
• Protective gloves

Materials / Replacement Parts

• Silicone-based lubricant spray (preferred) or light machine oil
• WD-40 or similar penetrating fluid (for rusted joints only)
• Replacement pivot pin or arm bracket (if damaged components are found)
• Dry cloth for wiping excess lubricant

How to Fix It: Step-by-Step

Step 1: Check What You’re Dealing With

Before you grab the oil, take a proper look at the arms. Stiffness has a few different causes and the fix depends on which one you’ve got.

• Extend and retract the awning slowly, watching where the resistance is coming from
• Check each pivot point along the arm for visible rust, corrosion, or grime
• Look for any bent sections of the arm that might be causing the arm to bind against itself
• Check the wall bracket fixings are secure and haven’t shifted, as misalignment causes stiffness too
• If the arm is cracked or visibly damaged, stop here and order a replacement part rather than forcing it

Step 2: Clean the Arms and Pivot Points

Dirt and dried-on grime are the most common cause of stiff awning arms. A good clean often sorts the problem before any lubricant is even needed.

• Mix warm water with a small amount of washing-up liquid
• Use the soft brush to scrub along the length of the arm, paying extra attention to the pivot joints and any folded sections
• Work the arm gently back and forth while cleaning to loosen debris from inside the joints
• Wipe everything down with a clean damp cloth and leave to dry fully before moving on
• For stubborn rust spots, apply a small amount of penetrating fluid, leave it to soak for 10 minutes, then scrub again

Step 3: Lubricate the Moving Parts

Once clean and dry, the lubricant goes on. Use silicone spray rather than WD-40 for ongoing maintenance. WD-40 is a water displacer, not a long-term lubricant, and it attracts dust over time.

• Apply silicone spray directly into each pivot point and joint
• Work the arm slowly through its full range of motion to distribute the lubricant
• Wipe away any excess from the surfaces of the arm, especially anywhere near the fabric
• Pay extra attention to the elbow joint if the arm has a double-arm articulated design, as this is the most common sticking point
• If you found rust earlier, apply the lubricant a second time after the penetrating fluid has done its job

Step 4: Test and Adjust

With the cleaning and lubrication done, run the awning through several full cycles to confirm the stiffness has cleared.

• Extend and retract the awning at least three or four times
• Listen for any grinding or clicking sounds that might indicate a component still needs attention
• Check that both arms move at the same speed. If one is lagging, it may need a second round of lubricant or further inspection
• If the awning has a motor, check the motor settings haven’t been affected before assuming the arms are still at fault
• Tighten any loose bolts or fixings at the wall bracket while you’re up there
