My Cover Seems Wet & Leaks
Wool is not 100% waterproof like plastic. Wool is a natural fiber and absorbs 30% of moisture that comes in contact with it and it slowly evaporates. If your cover leaks, it is possible that you are not using an absorbent enough diaper. Try using doublers for heavy wetters. Also, change your baby more often. It is also possible that this indicates it is time to relanolize.
While it is possible to use too much lanolin, this will not harm your cover. It will feel normal again after some wear. If it bothers you, you can rewash the cover using warm water and tad bit of dishwashing liquid like Dawn to help strip it back out, but you will need to lanolize again, using a smaller amount. This method will also work if you happen to get lanolin spots from uneven dispersement of lanolin in the wash.
Help, My Wool Covers are Bleeding Dye!
Occasionally some dark colors can bleed onto a really wet diaper or bleed into the wash water. I panicked when I put a deep red pair of longies on my son, and when I changed his crisp white diaper, it had turned pink. Don't panic, the dye that is used to color wool yarns will normally only adhere to wool and silk fabrics and is non-toxic. I put the pink diaper immediately in the diaper pail and washed it the next day normally and it came out just like new. Avoid washing your dark covers with the lighter ones too. Occasionally, it may take several washes for the dye to completely fade from the diaper, but it will come out. You can re-set the dye in your covers or any wool items that you have using the following method. Fill a large pot with enough liquid to totally immerse your cover. I like to use 2/3 white vinegar and 1/3 water. Turn your stove to medium-high heat and when it just starts to boil, add your wool cover slowly pushing down until it is totally immersed. Turn your stove down to maintain a simmer. Avoid heavy agitation. Bring your vinegar/water to a simmer and allow the cover to simmer for about 15 minutes. Turn the stove off and remove from heat and allow the cover & vinegar to return to room temp. Gently remove cover and squeeze out the vinegar. Run a sink of lukewarm water and your wool wash and gently wash the cover normally to remove the leftover vinegar. Your dye should now be set. Your water should be virtually clear with no excessive color leaching into it. You will not felt your wool doing this process as long as the wool is not exposed to drastic temperature changes combined with agitation. Make sure you only add your cover when the water is good and hot and make sure you leave the cover alone until it completely cools down.
