How to Get Tar Out of a Nylon Carpet
Getting tar out of a nylon carpet is possible at home but needs patience and honest expectations. The short version: absorb first with powder, then degrease with washing-up liquid — water alone will simply roll off it. Nylon Carpet is forgiving, so the main thing is method and order, not caution. There are situations here where a professional genuinely is the right call — they are flagged below.
What you’ll need
Recommended: Ice to harden the tar, then white spirit or a citrus-based tar remover on a cloth.
Homemade option: A bag of ice for the hardening stage; beyond that, white spirit from a DIY shop is the accessible solvent — there is no watery cupboard recipe for tar.
Dwell time: 15 to 30 minutes for the absorbent powder.
Step-by-step method
- 1
Chill the tar hard first: hold a bag of ice or a freezer block on it until it firms, then chip and lift every piece you can with a blunt knife — cold tar snaps away, warm tar smears.
- 2
Cover the mark generously with bicarbonate of soda or cornflour and leave it for at least 15 minutes — longer for a big spill. The powder pulls free oil out of the fibre.
- 3
Vacuum the powder away thoroughly.
- 4
Dab the remaining residue with a small amount of white spirit or a citrus-based tar remover on a cloth — never poured on — working from the edge of the mark inwards. Ventilate the room while you work.
- 5
Once the tar stops transferring, wash the spot with washing-up liquid solution to clear the solvent, dab with clean water and blot dry.
- 6
For a stubborn residue, apply a small amount of dry-cleaning solvent to a cloth (never directly to the pile) and dab, then air the area well.
- 7
Give the cleaned area one final plain-water dab and a firm blot even if it looks finished: nylon pile holds cleaning residue, and leftover detergent or solvent is what makes a cleaned patch re-soil faster than the carpet around it.
Why this works
Tar is bitumen — long heavy hydrocarbons that no household detergent can emulsify at any strength. It has two usable weaknesses: it turns brittle when cold, so most of it snaps off frozen, and it dissolves in petroleum and citrus solvents, which is what the white spirit stage exploits. Water plays no part because tar and water simply do not interact.
Don’t do this on a nylon carpet
- Do not apply water first — oil repels it, and wet fibre stops the absorbent powder working.
- Do not rub fresh tar; pressure spreads grease sideways through the pile.
- Never try to wipe or degrease warm tar — every touch while it is soft spreads it. Cold and brittle first, solvent second.
- The one hard rule on nylon: no chlorine bleach — it strips the carpet dye even in weak solution.
Working with solvents: this method involves a solvent or alcohol stage. Ventilate the room, keep the product off skin and away from flames, apply it to the cloth rather than the surface, and always spot-test somewhere hidden first.
Fresh spill vs dried-in stain
Tar walked in from fresh road surfacing is soft, sticky and spreads at a touch — chill it hard before doing anything. Older tar has firmed up, which actually helps: the bulk chips off cold, leaving a smaller solvent job. Either way this is a solvent stain; water plays no part.
Old oil oxidises into a sticky varnish that grips soil. Rework the degreaser stage several times, and accept that a solvent pass — or a professional with proper solvents — may be needed for a mark that has aged for weeks.
When to call a professional
Tar that has been walked across a room, or ground deep into pile, is honestly a professional solvent job — the spot method here suits one or two marks, not a trail. Professionals carry citrus gel solvents that dissolve bitumen without flooding the backing.
We don’t sell cleaning or take referral fees — when we say “call a pro”, it’s because the chemistry says so. Look for NCCA-registered firms.
Tar on nylon carpet FAQs
Will tar come out of a nylon carpet?
Sometimes — be honest with your expectations. Tar is one of the harder stains on this surface, and complete removal is not guaranteed. A professional improves the odds considerably.
What is the best cleaner for tar on a nylon carpet?
Ice to harden the tar, then white spirit or a citrus-based tar remover on a cloth. From the cupboard: A bag of ice for the hardening stage; beyond that, white spirit from a DIY shop is the accessible solvent — there is no watery cupboard recipe for tar.
Can I use chlorine bleach on a nylon carpet?
No. Nylon is the workhorse of carpet fibres: resilient, abrasion-resistant and tolerant of nearly every household cleaning agent except chlorine bleach, which strips its dye. Most stain methods can be used at full strength with confidence.
How long does a nylon carpet take to dry after treating tar?
1 to 2 hours. Nylon dries quickly — typically 2 to 4 hours after spot cleaning with airflow.
When should I call a professional for tar on a nylon carpet?
Tar that has been walked across a room, or ground deep into pile, is honestly a professional solvent job — the spot method here suits one or two marks, not a trail. Professionals carry citrus gel solvents that dissolve bitumen without flooding the backing.
