Drywall dust and joint compound residue can be tricky to clean up after drywall installation or repairs. Over time, they can accumulate on floors, countertops, and other surfaces. Thorough cleaning is required to remove all traces of drywall dust and dried joint compound. With some time and effort, you can get rid of drywall residue and have your home looking dust-free.

Necessary Supplies for Cleaning Drywall Dust and Joint Compound

Cleaning drywall dust and dried joint compound requires having the right tools and materials on hand. Here are some recommended supplies:

Vacuum cleaner – A standard household vacuum with hose attachments will help suck up loose drywall dust. Make sure to use a vacuum with a HEPA filter for best dust containment.
Microfiber cloths – Anti-static microfiber cloths attract and trap dust effectively. Dampen them slightly to pick up drywall dust.
Stiff nylon brush – A sturdy brush helps scrub off dried joint compound from walls and other surfaces.
Wet mop – For floor surfaces, a damp mop helps sweep up drywall dust.
Buckets – Use buckets for mixing cleaning solutions and for rinse water.
Sponges and scrub pads – These help scrub off stubborn dried joint compound.
Drywall joint compound solvent – Special solvents are made to dissolve joint compound for easier removal.
Vinegar – Helps cut through drywall dust and residue. Mix with water for cleaning.
Dish soap – Adds extra grease-cutting power to cleaning solutions.
Eye protection – Goggles protect eyes from airborne dust and cleaning sprays.
Dust mask – Prevents inhaling fine drywall dust particles.

Having the proper gear for the job will make drywall dust cleanup much smoother. Buy supplies before starting cleaning work.

Protecting Surfaces Prior to Drywall Work

The easiest way to deal with drywall dust and joint compound mess is to prevent it in the first place. Use protective coverings when possible before drywall installation, sanding, or repair work begins.

Cover Floors and Carpets

Floors and carpets inevitably get covered in dust and powdered joint compound during drywall finishing work. Lay down plastic sheeting, canvas drop cloths, or cardboard over flooring surfaces. Tape down the edges to keep them from shifting. The protective layers catch most of the drywall debris, keeping floors clean. Simply roll up and dispose of the coverings afterwards.

Mask Off Counters and Cabinets

Countertops and cabinets also require protection from drywall dust. Carefully apply painter’s tape around the edges to create a seal. Then lay plastic sheeting or heavy paper over the surfaces, securing it with more tape. This keeps hard-to-clean drywall residue from getting on counter and cabinet surfaces.

Use Window Coverings

Windows are magnets for airborne drywall dust. Prevent dust buildup by keeping windows closed and covering them with plastic sheeting or cardboard during drywall finishing work. Any dust or splatter that gets on the window coverings can be easily removed afterwards.

Taking the time to properly mask off areas before drywall installation saves cleanup effort later. Surfaces can simply be uncovered and cleaned off lightly rather than requiring heavy scrubbing to remove caked on residue.

Cleaning Up Drywall Dust

Drywall joint compound starts out wet but then dries to a fine powder. The dust clings to all types of surfaces and often seems impossible to fully remove. With some scrubbing and vacuuming, drywall dust can be cleaned up successfully.

Vacuum Walls, Ceilings and Floors

A thorough vacuuming is the first step in cleaning up drywall dust. Use a hose attachment to reach corners and crevices where dust collects. Vacuum walls, ceilings, and floors methodically to suck up all loose particles.

Be sure to use a vacuum with a HEPA filter, which traps tiny dust particles that would otherwise just get blown back out into the room. Change out vacuum bags frequently so they don’t get overly full and lose suction power.

Dust With Microfiber Cloths

For lightly coated surfaces, microfiber cloths attract and pick up drywall dust efficiently. Slightly dampen the cloths with water to help them grab more dust. Don’t soak them, as excess water will just spread the dust around.

Lightly run the microfiber cloths across walls, countertops, cabinets, and other areas. The static charge of the cloths traps dust that a dry cloth would simply redistribute. Launder the cloths after use to remove accumulated grime.

Damp Mop Floors

On hard flooring surfaces, use a barely moist mop to collect drywall dust without leaving a residue. Fill a mop bucket with warm water and add a small amount of floor cleaner or vinegar. Wring the mop out well so it is only slightly damp.

Mop floor areas methodically, rinse and wring the mop pad out frequently. The slightly damp mop head will pick up drywall dust without leaving a film or streaks behind.

Use Tack Cloths on Surfaces

Tack cloths are another option for capturing stubborn drywall dust. These have an adhesive coating that grabs and holds dust when lightly pressed against a surface. Tack cloths are especially useful on textured surfaces and detailed molding.

After tack cloth use, a quick wipe down with a dry microfiber cloth removes any adhesive residue left behind. Tack cloths only pick up dust – they do not actually clean surfaces. Follow up with a thorough cleaning method afterwards.

With some diligent vacuuming, dusting and mopping, drywall dust can be cleared away post-construction. Just be sure to reach every corner, crevice and surface to eliminate all traces of dust.

Removing Dried Joint Compound Residue

While drywall dust wipes up relatively easily, dried joint compound is much more stubborn to remove. Special cleaners and scrubbing is required to break down the plaster-like residue.

Use Joint Compound Solvent

Purpose-made joint compound solvents soften and dissolve dried bits of joint compound for easier removal. Products like Krud Kutter or Dif® dissolve joint compound on contact.

To use joint compound remover:

Shake the bottle well and apply some solvent directly onto the dried joint compound. Let it sit for a minute or two to penetrate.
Scrub surfaces with a stiff nylon brush to loosen residue. Re-apply more solvent as needed.
Wipe away the softened joint compound with clean rags or paper towels. Rinse the area with a vinegar-water solution.
Ventilate the area well, as solvents can produce strong fumes.

Joint compound solvents are highly effective but should be used cautiously by following the manufacturer’s directions.

Make a Vinegar Cleaning Solution

For a non-toxic option, make a DIY drywall cleaner by mixing:

1 cup white vinegar
1 gallon warm water
1 tablespoon dish soap (optional)

The acidic vinegar breaks down dried joint compound. The dish soap helps boost grease-cutting power.

Dip a scrub brush or scrubbing pad in the solution and scour affected areas. Wipe away the loosened residue with a damp cloth.

For heavier buildup, apply the vinegar solution and let it soak for 5-10 minutes before scrubbing. Rinse cleaned areas with a second vinegar-water wash.

Scrub and Rinse Walls and Ceilings

Use a cleaned bath or utility tub to wash walls and ceilings. Fill the tub partially with warm water and mix in 1 cup of vinegar.

Dip a stiff nylon brush or scrubbing sponge in the tub. Scrub affected areas of walls/ceilings with the brush, re-dipping frequently. The vinegar solution will dissolve joint compound buildup.

Use a plastic cup to rinse the cleaned areas with fresh water. Have a second bucket on hand for capture rinse water. Change it out frequently to avoid redepositing residue.

Work in sections until walls and ceilings are cleaned. Wear protective eyewear when rinsing overhead. Let areas fully dry before repainting.

Clean Counters, Cabinets and Floors

Use the vinegar-water mix to scrub counters, cabinets, and floors too. Apply the solution and let it soak for a few minutes before scrubbing with a nylon brush or pad.

Wipe down surfaces with clean water and a microfiber cloth or squeegee. Rinsing thoroughly prevents sticky residue.

For floors, use a mop and two buckets – one for the cleaning solution and a second bucket of rinse water. Change out water frequently.

With some concentrated scrubbing using the right cleaners, stubborn dried joint compound can be removed successfully. Just take care to thoroughly rinse off any cleaning product residue.

Cleaning Drywall Tools

While cleaning job sites, don’t neglect drywall tools. Leaving dust and residue on tools can lead to corrosion and damage over time. A bit of maintenance keeps tools performing well.

Blow Off Drywall Sanding Dust

After drywall sanding, blowing air removes loose dust before it cakes on tools. Use a shop air compressor if available. Or use pressurized air cans made for dusting electronics.

Hold the air nozzle several inches away and blast all accessible surfaces of tools. This clears residue from crevices and prevents clogging of moving parts.

Knock Off Dried Joint Compound

Tap tools against a work bench or wall to dislodge any chunks of hardened joint compound. A wire brush also helps scrape off stubborn dried bits.

Soak any tools with a thick buildup in warm water mixed with a little vinegar solution – this softens dried joint compound for removal.

Clean Metal Tools with Vinegar

Wipe down metal drywall tools like taping knives, trowels and metal sanding poles with white vinegar on a rag. The mild acid in vinegar removes residual plaster and hard water deposits.

For rust spots, use vinegar and sprinkle on baking soda to make a foaming paste. Scrub this paste on rust spots with a nylon brush, then rinse clean. The chemical reaction helps remove oxidation.

Wash Tools with Soap and Water

Use a mild dish detergent and warm water to wash drywall tools. Dip scrub brushes in the soapy water and thoroughly clean surfaces, getting into crevices.

Rinse tools well with clean water and dry with a rag. Allow metal tools to fully air dry before storing, to prevent moisture-related corrosion.

Keeping drywall tools free of residue maintains their performance and longevity. Plus, it prevents transferring old dried material to new jobs. Get in the habit of cleaning tools at the end of each workday.

Tips for Containing Drywall Dust

Containing drywall dust while working makes final cleanup much easier. Here are some useful tips for keeping dust under control:

Seal off doorways and ventilation ducts with plastic sheeting to prevent dust spreading.
Position a box fan blowing out a window to ventilate the workspace during dusty tasks.
Wear a dust mask and eye protection when sanding or demoing drywall.
Use tools with dust collection – like sanders with vacuum hose attachments.
Mist areas lightly with water before sanding to minimize airborne dust.
Vacuum frequently during the job rather than waiting until the end.
Choose low-dust joint compounds or EIFS repair products when available.
Wrap furnishing and fixtures in plastic instead of trying to clean them later.

Putting in work upfront to contain dust saves cleanup labor in the long run. It also prevents the frustration of dealing with dust migration into other rooms.

When to Call in a Professional for Cleanup

Extensive drywall finishing projects often create more mess than a homeowner wants to tackle themselves. Construction crews specialize in cleaning up job sites thoroughly.

Professional drywall contractors have the powerful equipment needed for large-scale dust and debris cleanup. They also have expertise in containing dust and proper disposal practices.

Calling in the pros to handle construction cleanup:

Saves homeowners significant time and hassle.
Ensures a thorough, high-quality cleaning job.
Reduces potential health hazards from improper dust management.
Allows scheduling dust remediation separately from finishing work.

For major drywall installation or finishing projects, the cleanup costs are well worth it. Professionals complete the job efficiently so residents can get back to normal life dust-free.

Maintaining Good Indoor Air Quality After Drywall Work

Even after a thorough cleaning, drywall dust particles may continue circulating through a home’s HVAC system. Extra steps help capture residual dust and restore healthy indoor air quality.

Change out air filters – Replace furnace and AC filters frequently over the next few months to catch lingering dust. Consider upgrading to pleated MERV 13 filters which trap more particles.
Use high-quality vacuum cleaners – Invest in a vacuum with sealed HEPA filtration to continually filter indoor air. Central HEPA-filter whole-home vacuums are ideal.
Run air purifiers – Portable HEPA air purifiers offer extra filtering and can be moved room-to-room as needed. Let them run continuously at first, then as needed.
Increase ventilation – Maximize fresh air circulation by opening windows, using bathroom and kitchen fans, and running HVAC fans.

Taking proactive steps improves indoor air quality and removes hidden drywall dust. This provides a healthier home environment post-construction.
