We know it seems counter intuitive, but the top of your mattress [or the rest of it for that matter] cannot be washed or dry cleaned. We strongly advise all of our customers to us a mattress cover or pad to protect their Spindle just as they would any other mattress.
Our design, does however, provide the opportunity to refresh the cover. Unzip the top of the mattress and hang it outside in the sun and let the UV rays and fresh air do their thing. If the mattress does get soiled you may be able to gently spot clean the stain. In a small container or an empty salt-shaker, combine half a cup of baking soda with 10 drops of your favorite essential oil and sprinkle the mixture over the mattress cover. Wait a few hours and then shake the top outside or vacuum up the baking soda with a hand vacuum or upholstery attachment, being careful not to tear the cover.
You can try to spot clean it with a little bit of water and vinegar. Just dab the spot. Be careful to not saturate the cover; this risks damaging the wool. If the cover does get wet, gently blot the area dry with a clean towel. Then cover the wet area with salt (yes, salt, who knew?) and leave for 4-6 hours. Then shake outside or vacuum as above.
In case the mattress or latex becomes unusable, we sell replacement parts to Spindle owners for 30% off street price. If you ever want to replace the cover, you may, but the entire cover must be replaced. The zipper for the border/side panel is mated to the zipper for the top quilting. The covers are sewn by hand on a sewing machine so the top zipper will not usually mate to the lower part. Plus, the stretch and elasticity of these soft goods make it difficult to make universal parts. We are incredibly sorry for the hassle.
