Assos Cleaning Kit

Why Standard Detergents Work Against Your Kit

Biological washing powders and liquids contain protease and amylase enzymes - effective at shifting food stains on a cotton shirt, genuinely destructive to high-performance cycling fabrics. Elastane and Lycra rely on long, interlocked polymer chains to maintain their compressive fit and four-way stretch. Biological enzymes attack those chains directly, causing gradual but irreversible breakdown. You won't notice it after one wash, but after a season of bio detergent, your Assos bib shorts will have lost measurable compression and the chamois pad's memory foam will have stiffened or thinned. Optical brighteners - common in standard detergents - add a further layer of damage, degrading the technical coatings woven into high-end fabrics.

The Assos Active Wear Cleanser sidesteps all of that. Its pH-neutral chemistry lifts dirt and odour without triggering enzymatic degradation. At the antibacterial level, it targets the bacteria that colonise chamois pads and base layer fabrics during long efforts - bacteria that survive low-temperature rinses in ordinary detergent but are neutralised here. For riders who store damp kit in a warm changing room or airing cupboard (which describes most of the UK between October and April), that antibacterial action is genuinely useful rather than a marketing afterthought. Fabric breathability is also preserved: the cleanser doesn't leave the residue film that bio powders deposit, which can block the micro-pores in technical fabrics responsible for moisture management.

Getting the Wash Right

Before anything goes in the machine, shake or rinse off heavy surface mud under a cold tap. UK road grit is abrasive enough to micro-tear Lycra fibres if it's tumbled around dry in a drum - a thirty-second cold rinse at the sink before loading is worth doing. Turn all garments inside out: the side doing the work - against your skin - takes the most contamination and benefits most from direct contact with the cleaning solution.

Bib shorts and any garment with suspender straps should go inside a mesh wash bag. The straps will tangle around other items in the drum otherwise, creating localised tension that stresses the fabric at the joins. Place the bag loosely - don't overstuff it. Dose one to two capfuls of cleanser into the detergent drawer depending on load size, then select a delicate cycle at a maximum of 30°C. Don't be tempted by a hotter setting; elastane preservation depends on keeping temperatures low, and the cleanser is formulated to work effectively within that range. Knowing the best detergent for cycling kit is one thing - using the right wash settings alongside it is the other half of the equation.

Once the cycle finishes, air-dry everything away from direct heat sources. Radiators, tumble dryers, and direct sunlight all accelerate elastane breakdown and can compromise DWR treatments on Assos jackets and gilets. Hang bibs from the waist rather than the straps, and give items space to dry rather than bundling them together - particularly important in humid UK utility rooms where damp-smell bacteria thrive if airflow is restricted.

What Else It Works On

The Assos Cleaning Kit isn't limited to Assos apparel - the formula is compatible with any brand's cycling kit, so it's a single solution for a mixed wardrobe. That said, it's worth understanding where it does specific heavy lifting. Chamois cream build-up is the obvious one: Assos Chamois Cream contains lanolin and other emollient compounds that standard detergents struggle to fully break down, leaving residue in the pad that hardens over time and becomes a bacterial breeding ground. The Active Wear Cleanser's formulation is designed to cut through that build-up properly, keeping the chamois hygienic and the foam responsive. If you're riding long audax distances or multi-day tours, chamois pad hygiene isn't a trivial concern.

On the DWR question: many riders assume that washing waterproof or water-resistant outer layers will degrade their treatment, and with bio detergents, that's broadly true. The pH-neutral formula here is safe on factory DWR coatings, so your winter jacket's beading performance won't be compromised by regular washing. In fact, cleaning the fabric surface properly can restore some DWR performance, as contamination from road spray and sweat is often what causes water to wet out rather than bead. If you're pairing the cleanser with Assos base layers, the same logic applies - technical fabrics need clean pores to wick effectively, and a residue-free wash makes a practical difference to next-ride comfort.

One practical note: the Assos active wear cleanser works on a small hand-wash load too if you're travelling or washing a single item post-event. A capful in a sink of cool water, a gentle agitation, and a thorough rinse is sufficient. It won't damage the fabric even at higher concentrations than the machine-wash dose.
