To prevent garments from shrinking and to keep them looking their best, wash at 30°. - Place delicate items in a mesh bag to help prevent snagging or twisting during machine cycles. - Pre ‑treat stains before washing by dabbing a small amount of stain remover on the area. For darker pieces, patch test on an inside seam to check the color won’t be affected. - Hang cotton out to dry, as heat from tumble dryers can cause it to shrink. This also saves energy.
