A lot of Louisville households have a quilt somebody in the family made. It is on a guest bed, or folded over a chair, or in a cedar chest because nobody is quite sure what to do with it.
The uncertainty is reasonable. An old quilt is not like other bedding, and the instinct to treat it carefully is correct. But careful frequently turns into never, and a quilt that sits folded in the same crease for thirty years is being damaged by the caution meant to protect it.
Here is how to handle one without wrecking it, and the same principles cover wool blankets.
Decide whether to wash it at all
Not every old quilt should go in water. Before anything else, work out what you have.
Test the dyes. Dampen a white cloth and press it firmly against each distinct fabric in the quilt, especially reds, deep blues, and blacks, which were the least stable historically. If any color transfers to the cloth, do not wet the quilt. Period dyes bleed, and once a red runs into surrounding white cotton it is permanent.
Check the condition. Look for splitting fabric, loose seams, and areas where the stitching has given way. Wet fabric is heavier and weaker, and a quilt with fragile spots can tear under its own waterlogged weight.
Consider what it is. If a quilt has real family or historical value, a textile conservator is a better call than a washing machine. That is a narrow category and most family quilts are not in it, but it is worth thinking about for a moment rather than not at all.
If the dyes hold and the structure is sound, you can wash it.
Washing an old quilt
Vacuum it first. Use the upholstery attachment through a piece of nylon screen or netting laid over the surface, which lets dust through and keeps the vacuum from pulling at loose threads. This alone removes a surprising amount and sometimes it is all a quilt needs.
If you are washing it, do it in a bathtub rather than a machine when the quilt is old or hand-stitched. Cool water, a small amount of a gentle detergent with no optical brighteners, and no agitation. Press it down gently with flat hands to move water through, and let it soak.
Drain, then rinse repeatedly until the water runs clear. This takes longer than seems reasonable. Detergent left in old cotton causes yellowing over time.
Never wring it or lift it by one edge. A soaked quilt is extremely heavy and the weight will pull seams apart. Press water out gently, then lift it as a supported bundle with both arms underneath, ideally with a second person.
Dry it flat. Spread it on clean sheets on the floor or across a bed, turning occasionally. Outdoors in shade on a dry day works well and is faster. Never in direct sun, which fades old dyes fast, and never in a dryer.
A sturdy machine-quilted piece from the last few decades is a different animal and handles a gentle cold cycle in a large front-loader without drama. The tub method is for the old ones.
Wool blankets
Wool has its own rules and they are simple once you know them.
Wool felts when three things happen together: heat, moisture, and agitation. Remove any one and it is fine. So cold water, minimal handling, and no tumbling.
Use a wool-specific detergent or a small amount of gentle detergent. Never use anything with enzymes, because wool is a protein fiber and enzyme detergents are designed to break protein down. That is the ingredient that eats wool.
Soak in cool water, press gently, rinse in water of the same temperature. Temperature shock is as damaging as heat, so do not rinse cold wool in warm water.
Roll it in towels to press water out, then dry flat, reshaping as it dries. Never hang wet wool, which stretches it permanently.
Wool mostly does not need washing. Airing it outdoors on a dry day handles odor, because wool is naturally resistant to bacteria. Once a season is plenty.
Storage, where the real damage happens
Most quilt damage is storage damage, accumulated slowly.
Refold along different lines once a year. Fibers break down along permanent creases, and a quilt folded the same way for decades develops splits along the fold lines that cannot be repaired. Rolling around a tube is better than folding.
Never store in plastic. Plastic traps moisture, and in Louisville’s humidity that means mildew. Cotton is also slightly acidic over time and plastic holds those byproducts against the fabric. Use a cotton sheet or a pillowcase.
Be careful with cedar chests. Cedar oils can stain and yellow fabric over decades. Line the chest with a clean cotton sheet so the quilt never touches the wood.
Keep it out of the basement and the attic. Basements are damp, attics swing between extremes, and both are worse than an interior closet.
Do not store it in direct light. Even indirect daylight fades dyes over years.
Moths, which are a real problem for wool
Moths do not eat cotton. They eat protein fibers, so wool blankets are the item at risk, not the quilt unless it has wool batting.
Moths lay eggs in fabric carrying body oil and sweat, so store wool clean. A wool blanket put away dirty is far more likely to be damaged than one put away washed.
Cedar and lavender repel to a limited degree and do not kill eggs. Airtight storage in a sealed bag or bin does more, provided the wool went in completely clean and dry.
For the pieces that can go in a machine
Modern quilts, comforters, and sturdy wool blankets all need room to move, and a household washer packed with one cannot rinse it. Detergent stays in the batting, which for wool means residue against the fiber and for cotton means slow yellowing.
The machines at our self-service laundry on East Oak have the drum volume for a full quilt or blanket to move freely on a gentle cycle, and the water volume to rinse it properly, which is the part that matters most for anything you intend to keep.
Our wash-dry-fold service handles bedding if you would rather not manage it.
The short version
Test the dyes with a damp white cloth before wetting any old quilt. Vacuum through netting, which is often enough. Wash old pieces by hand in a cool tub, never wring, dry flat out of the sun, never in a dryer. Wool wants cold water, no enzymes, no agitation, dried flat. Refold quilts along new lines once a year, store in cotton rather than plastic, line the cedar chest, and store wool clean because moths go after the oil in it.
