It is important to regularly clean the tombstone, so as to prevent mold, stains, soot and dust, and to preserve its good condition and durability over the years. Likewise, the weeds and grass that grow wild around it need to be frequently removed.
Despite the fact that it is optimal and recommended to visit the grave and clean and maintain it on a regular basis, this is frequently impossible due to distance or a lack of time or ability. Many people are interested in preserving and honoring the memory of their loved ones but cannot come personally and maintain the grave due to various difficulties.
