how to clean chalkboards
I have been a custodian for only about 1 month and I was wondering how I should clean chalkboards. My boss said they are not the old slate boards, but sheetrock with a coating. |

Re: how to clean chalkboards
I use a rag dipped in a bucket of water and wring out until it is just wet. Not drippy wet and not too dry. Back and forth I go, making certain that I overlap the previous run as I work my way to the bottom of the board. Depending on the size of the board, I usually have to turn the rag over once I see the chalk starting to streak or rinse the rag off before I continue. Some people have a seperate dust mop (yes, ones used on the floor) to clean the boards quickly. I only use this method if I am pressed for time. |

Re: how to clean chalkboards
Hi all, Back in the day, Chalkboards used to be cleaned regularly but with cutbacks and workload increases they are usually left till christmas break, spring break and summer cleanup. But when i do clean them I prefer to use ammonia (Sudsy) in bucket. Just about half a cup will do in 2 gallon pail of hot water. First I get my rag good and wet. Wring out just lightly, you still want it quite wet and then wipe down board. Afterwards just take a squeegee and starting at one corner at top of board swipe left to right and work your way down. It is quite effective and doesn't leave much residue behind. The ammonia seems to allow the chalk to cling to rag. If streaks appear after board dries then using a clean rag and ammonia solution just wipe olong to do it this way. Just remember to ask teacher if he/she has writing on board if ok to clean off first. You don't want to **** off a teacher by wiping off any assignments. LOL! Works for me! Mr. Janitor |

Just wring rag out first before that. If streaks appear after board dries then using a clean rag and ammonia solution just wipe olong to do it this way.

Re: how to clean chalkboards
get a window washing kit with lambswool pad and a squeege,fill bucket with plain water, most boards you can make 3 passes with the wet lambswool pad, then squuegge dry, i then use a damp rag for the edges and board track, with also wiping the eraser's |

Re: how to clean chalkboards
Guess I'm lucky, as most all of my teachers use an overhead now instead of chalkboards. My one tip simply is: wear rubber gloves! In the "olden days" when I cleaned boards often, I found chalk to be very dehydrating for my hands. |

Re: how to clean chalkboards
Well, after reading these comments I just had to put my 2 cents in..chalkboards should not be cleaned off. you rub off the board with a chalk brush and then take a 1 foot board brush and hold it angled out so just the edge of the brush is makeing contact and you pull it from one side to the other, drop down and repeat untill board is done. This is called chalking and you must keep chalk on the board so when the teacher is writing the letters dont "ghost"..ghosting is caused by the hand or palm touching the board and leaving an oily residue.When the chalk stick goes through the oil it fades or ghosts. I have been doing this for the past 6 years and the boards look good when done and the teachers love it ( you need to explaine ghosting to most teachers, but they know when you tell them and agree.) |
