Drawing pins, thumb tacks, and staples are used to secure temporary floor coverings (runners, plastic sheeting during renovations), signs, cable runs, or fabric to carpet. When removed, they leave small puncture holes in the pile face and backing, compressed pile marks around the puncture point, and sometimes rust staining from the metal pin shaft. Rental properties and commercial carpet are particularly affected — end-of-tenancy inspections frequently identify pin damage from pictures, signs, or temporary flooring secured to carpet.
Pin and tack damage types
- Small puncture hole in pile face — visible as a tiny dark dot in the carpet surface
- Compressed pile ring around the puncture point from the pin head pressing down
- Rust staining from a steel pin left in carpet, especially in damp conditions
- Multiple small holes in a line or grid from staples or row of tacks along a seam
Restoring compressed pile around pin holes
- Place several ice cubes directly over the compressed area and allow them to melt fully — typically 30 to 60 minutes.
- As the water is absorbed, the pile fibres begin to swell and lift.
- Once the area has dried, use a stiff brush or fork tines to work the pile fibres back to an upright position.
- For stubborn compression, hold a clothes iron several centimetres above the pile (not touching) and steam the area briefly, then brush the pile upright.
Treating rust staining from steel pins
- Remove the pin if still in place.
- Apply white vinegar to the rust stain with a cloth and allow 5 minutes dwell time — the acid dissolves iron oxide.
- Blot and rinse with cold water.
- For persistent rust staining, a commercial rust remover suitable for fabric (available at hardware stores) applied per the product instructions can address deeper staining.
- Rinse thoroughly after any rust treatment to remove the acid from the pile.
Repairing the puncture hole itself
A small puncture hole in cut-pile carpet is usually not visible once the surrounding pile is restored to an upright position — the surrounding fibres obscure the tiny opening. In loop-pile carpet, a pin that has broken a loop creates a small exposed fibre end; a carpet repairer can re-anchor the loop end to prevent the break from extending into a run. Multiple puncture holes in a line (from a row of staples) may require a patch repair if the damage is concentrated and visible.
Never use pins or tacks to secure items to carpet
Pins and tacks damage the carpet backing as well as the pile face. In cut-pile carpet, backing damage weakens the weave and can cause pile loss around the puncture over time. For securing temporary floor coverings, use double-sided carpet tape rather than pins — it holds without puncturing and removes cleanly. For securing signage or cable runs, use adhesive hooks on adjacent walls rather than pinning through the carpet.

Frequently asked
There is a row of about 20 staple holes across the carpet near the doorway where a temporary runner was secured. The holes are in a straight line and visible as a darker line. What can I do about this?
A row of staple holes presents as a darker line because the small punctures in the pile create a shadow effect where light enters the pile at a slightly different angle. The ice-and-brush treatment applied along the full length of the row lifts compressed pile around each puncture point. Once the pile is restored, the visible line typically fades significantly or disappears in cut-pile carpet — the upright surrounding pile covers the small openings. If some holes in the row remain visible after pile restoration, a professional carpet cleaner can assess whether a seam repair or patch is warranted for the most damaged section.
A drawing pin was left in the carpet for several months. When I removed it, it had rusted and there is now a rust-coloured ring stain around the hole. The stain is about 1 cm across. How do I treat this?
A rust ring from a corroded pin is an iron oxide stain — white vinegar is the first treatment (the acid dissolves iron oxide on textile fibres). Apply white vinegar, leave 5 minutes, blot, and rinse with cold water. For a 1 cm stain that has been in place for months, a second treatment round or a commercial fabric rust remover may be needed. Do not use bleach on rust stains — bleach reacts with iron oxide and can darken the stain. Rinse any acid treatment very thoroughly because residual acid in the pile can weaken the fibre over time.
The carpet in a rental property has about 50 pin holes from picture hooks and cable management pins across multiple rooms. The property manager says this is carpet damage. What is the repair approach?
Fifty pin holes across multiple rooms is a significant number. Individual pile restoration using the ice method applied room by room addresses the compressed pile around each hole, which accounts for most of the visual impact. Rust staining at any pin location is treated with white vinegar. The remaining visible puncture openings in cut-pile carpet after pile restoration are typically very small (1–2 mm) and largely invisible at standing height. For any holes that remain visually prominent after treatment, a professional carpet repairer can assess patch options. In a rental context, a professional carpet cleaning report documenting the treatment performed and the post-treatment condition provides useful evidence of remediation.
I removed a temporary floor covering that was held down with a tack strip around the perimeter. The tack strip has left a continuous indentation ring around the room perimeter. Is this repairable?
A perimeter indentation from a tack strip is essentially a long version of the furniture dent problem — the ice method applied along the full perimeter length is the treatment. Work in 30–50 cm sections, applying ice, allowing it to melt, then brushing the pile upright before moving to the next section. A perimeter indentation that runs the full length of the room is a large job done in sections rather than all at once. Tack strips used to secure temporary flooring over existing carpet are generally not recommended for this reason — the continuous compression along the perimeter leaves a persistent mark.
