Olefin
The only textile fibre in this catalogue that chlorine bleach does not decolour. That single property changes where it belongs and what may be used on it.
In detail
Olefin is polypropylene spun as a fibre, used widely in carpet, rugs and outdoor textiles. Its defining property for cleaning is one no other fibre here has: a professional body describes it as BLEACH-PROOF, and recommends it for laundry rooms and areas near swimming pools for exactly that reason. Where chlorine bleach takes the colour out of almost every other textile permanently — correctable only by dyeing or patching — olefin keeps it, because the colour is in the polymer rather than applied to it. That does not make it robust. It is a polyolefin, so it is OLEOPHILIC: oily soil is chemically similar to the fibre and is held tenaciously, which is why olefin carpets look greasy in traffic lanes while resisting water-based stains. Solvent has to be used carefully for the same reason. And it is one of the two fibres a professional body names as exceptionally hard to clear of filtration soiling, the fine airborne particulate that embeds at room edges. So the sequence inverts. On most textiles the water-based stain is the easy one and bleach is the catastrophe; on olefin bleach is survivable and the body oil from bare feet is the problem.
What works
Sodium hypochlorite (chlorine bleach) is safe on, in specific conditions, Olefin
Safe only in specific conditions
This is only appropriate within specific limits. Outside those limits, CleaningHQ makes no claim.
Only within these limits:
- The fibre must actually be olefin — most readers cannot tell, and being wrong is irreversible
- Bleach-proof means the COLOUR survives; it is not a clearance for the backing, the adhesive or anything underneath
Recorded because it is the single exception in a category where everything else is permanent damage, and because a manufacturer recommends the fibre for laundry rooms and poolside areas on exactly this basis.
Why we say this
Supported
Held at CONDITIONAL rather than established, because the source establishes the fibre's colourfastness and nothing about the assembly the fibre is part of.

Relied on for: That olefin fibres are bleach-proof, are the one exception to chlorine bleach causing colour loss on textiles, and should be considered for carpeted laundry rooms and areas near swimming pools. (states this directly)
Verification: a person has read the passage relied on.
Read on — All twenty-five numbered topics. The damage sections (17-25) and the animal, mould and residue sections carry most of what was new. Supports a wider statement — our claim was widened. The single richest source this register has acquired. It supplies six mechanisms nobody here held — wicking, cellulosic browning, filtration soiling, rapid re-soiling, delamination and phenolic yellowing — and every one of them is a case of DIRTY VERSUS DAMAGED, the distinction this catalogue is built on. It also closes the pet-odour question Sprint 48 left partial: the reason the smell returns in humid weather is a reservoir in the backing and padding that surface cleaning never reached, not the rehydrating uric-acid story consumer pages tell.
