Car cleaning cloths: types of microfiber and how to tell good quality

Microfiber is the right cloth for almost every job on a car, but only good microfiber. Look for a 70/30 or 80/20 blend, no tags, soft edges, and a weight and weave that suit the job. Indonesian drivers call these cloths lap mobil, and the choice in shops has exploded: cheap packs, plush buffing towels, waffle glass cloths, twisted loop dryers and synthetic chamois all sit on the same shelf.

Microfiber vs chamois vs cotton

Microfiber wins for paint. Chamois still works, and cotton belongs on the dirty jobs.

Microfiber is a synthetic fiber finer than one denier, under 10 micrometers across (Wikipedia). Car towels are usually split polyester and polyamide. Splitting is what makes the fibers grab dirt and water, and Wikipedia describes unsplit microfiber as "little more than a very soft cloth."

Chamois is traditionally oil-tanned leather. In the US, plain "chamois" must come from the flesh split of sheep or lambskin tanned only with oils (Wikipedia). It's absorbent and barely abrasive, but it has no pile to lift grit away. Adam's Polishes says a thin chamois can drag grit across the surface and leave long, faint scratches, and real leather can start to smell over time.

Synthetic chamois is usually PVA. The Absorber, a common one, is sold to be stored damp in its tube so it's ready to use (Ace Hardware). Adam's calls synthetic chamois stiff and says it can leave droplets in panel gaps.

Cotton is a poor paint towel. Adam's says bath and beach towels aren't soft enough for clear coat, can swirl it and often carry stiff nylon tags. Auto Finesse, which sells microfiber, still suggests cotton for greasy engine bays, wheels and exhaust tips.

Auto Express says drying has moved on from chamois leather to microfiber, which it finds more absorbent and gentler on paint.

How to read the label: GSM, blend and weave

GSM is grams per square meter, a measure of weight and density. Higher GSM means a thicker, plusher towel that holds more water or residue (Jalopnik). A 245 GSM towel feels thin and direct. A 500 GSM towel feels plush (Clean and Shiny).

Blend is polyester first, polyamide second. Polyester is cheaper and gives structure. Polyamide adds softness and absorbency (Clean and Shiny, Jalopnik).

• 70/30 is the softer, more absorbent blend. Clean and Shiny calls it the "gold standard" for drying, buffing wax and quick detailer.
• 80/20 is the most common blend (The Drive). Clean and Shiny prefers it for coating removal, glass and wipe-downs where you want control over plushness.
• 90/10 or 100% polyester is cheaper and rougher. Clean and Shiny says it's unsuitable for paint and raises the risk of marring on soft paint and gloss black trim.

Weave decides what the towel is good at.

Weave matters as much as weight for drying. Auto Express soaked 13 drying towels and measured what they held. The CarPlan Demon Micro, a ribbed microfiber, held 6.4 liters per square meter and dried a hatchback without wringing. A light waffle-weave towel held only 1.45 liters per square meter, the lowest in the test.

Edgeless vs edged towels

Edgeless is the safer choice for paint. Edges and tags are where cheap towels scratch.

Overlock stitched edges are durable and resist fraying, which suits all-purpose towels (Clean and Shiny). Knife-cut and ultrasonic-cut edgeless towels have no seam to drag across the paint. Suede borders are a soft middle ground.

The bad version is the melted edge. Adam's says heat-sealed edges on cheap towels can be "even sharper than the sewn-in tags." Ripping out a tag doesn't fix it either, because the stitching stays behind.

How to tell good quality in the shop

You can judge most towels before you leave the shop.

• Read the pack for GSM and blend. No numbers at all is a bad sign.
• Look for 70/30 or 80/20 for paint. Skip 90/10 and 100% polyester for anything glossy.
• Check every edge and corner for tags, hard stitching or melted plastic.
• Feel it. Adam's says cheap towels feel thin and rough and cling to your fingers.
• At home, push a little water across a smooth surface with it. If the cloth pushes the water instead of soaking it up, the fibers aren't split (Wikipedia).

Which cloth for which job

Keep separate towels for paint, glass and dirty work.

One habit matters more than any spec. If a towel hits the ground, it's done for paint until it's been washed. Jalopnik warns that dropped towels pick up particles that scratch.

How to wash microfiber

Wash it warm or cold, with liquid detergent and no softener. These numbers come from The Rag Company's care guide.

• Use 1 to 2 oz of liquid microfiber detergent per load. Skip powders and pods.
• Warm or cold water only. Avoid hot water and sanitize cycles.
• No fabric softener, dryer sheets or bleach. Softener coats and clogs the fibers.
• Wash microfiber away from cotton, and keep wheel and engine towels away from paint and glass towels.
• Add an extra rinse. For towels stiff with wax or coating, soak them in warm water and detergent for 24 to 48 hours first.
• Tumble on low or no heat, or air dry. Clean the lint trap before every load.

Looked after like this, good towels last. Jalopnik puts it at about 200 to 500 washes, and Detailed Image says over 100 even with real detailing use.

What car cloths cost

Price tracks blend, GSM and size, and the top end is mostly about drying towels.

Products worth a look

• Kirkland Signature microfiber towels: cheap, 80/20 and plentiful, which makes them good dirty-job towels. The listing gives no GSM, so check the feel and edges before trusting them on paint.
• The Rag Company Edgeless 300: a soft 70/30 edgeless all-rounder for detail spray and wax removal. At 300 GSM it's too thin to dry a whole car.
• The Rag Company Liquid8R: a 70/30, 1,100 GSM twisted loop drying towel with a hidden hemmed edge. The drawback is price: one 20 x 24 inch towel costs more than a 36 pack of Kirkland cloths.
• The Absorber synthetic chamois: cheap, stores damp and wrings out fast. Adam's notes it's stiff and can leave water in panel gaps.

What to do today

1. Sort what you own into paint, glass and dirty-job piles. Anything with a stiff tag or melted edge leaves paint duty.
2. Buy one heavy twisted loop drying towel and a few 70/30 edgeless towels before anything else.
3. Add two or three waffle or pearl towels for glass, and keep them only for glass.
4. Wash every towel before its first use, then after every use, with liquid detergent, no softener, and low or no heat.
5. Move old cotton towels to the garage for engine bays, wheels and exhaust tips.
