How To Get Sand Out Of A Hot Tub

Understanding Sand and Debris in Your Hot Tub

Common types of debris found in hot tubs

  • Sand and grit: The most common culprits giving you that “beach in your spa” feeling (not in a good way!)
  • Organic matter: Those sneaky leaves, dirt clumps, and natural debris that decompose in your water
  • White powder/limescale: That chalky stuff appearing due to calcium deposits in hard water
  • Flakes and particles: Sometimes coming from your aging filters or jet diffusers

How sand and grit enter your spa

  1. Human transportation: The number one culprit! Sand hitches a ride on feet, swimsuits, and skin (especially after beach days)
  2. Environmental factors: Windy days can blow sand and soil right into your spa, particularly if you live near beaches or construction
  3. Deteriorating components: Sometimes what looks like sand is actually your filter material breaking down over time
  4. Chemical additives: Some spa chemicals contain tiny particles that can build up gradually

Why immediate removal is important

Do’s and Don’ts of Hot Tub Debris Management

DoDon’t
Remove debris as soon as you spot itIgnore even tiny amounts (they multiply like rabbits!)
Clean filters regularlyWait until weird noises or poor performance happen
Cover your hot tub when not using itLeave your spa exposed to nature’s whims
Rinse off before hopping inLet sandy feet march straight into your clean water
  • Jet inserts: They stop spinning, start misbehaving, or completely fall apart
  • Pump impellers: Sand gradually wears them down, making water flow weaker
  • Heater elements: Protective coatings get scratched away, leading to early failure

Quick DIY Methods to Remove Sand from Hot Tubs

Quick DIY Methods to Remove Sand from Hot Tubs

Using a turkey baster technique

Step-by-step turkey baster technique:

  1. Squeeze the bulb completely (bye-bye, air!)
  2. Place the tip directly over the sandy spot on your tub floor
  3. Release the bulb slowly to create suction (like a mini vacuum)
  4. Keep that baster underwater while hunting for the next sandy patch
  5. Lift it out once full (careful not to squeeze!)
  6. Dump the sand far away from your spa
  7. Repeat until you’ve nabbed all the visible grit

Pros and Cons of Turkey Baster Method:

Pros

  • Super cheap (about $1)
  • Pinpoint accuracy for small spots
  • No need to drain water
  • Easy to tuck away

Cons

  • Takes forever for large areas
  • Limited sand-sucking capacity
  • Need a new one for kitchen duty after
  • Not great for deep-settled sand

The waterproof putty method

How to use waterproof putty:

  1. Grab some waterproof silly putty (toy stores have plenty)
  2. Plop it directly onto the sandy area
  3. Press down gently but firmly (don’t squish too hard)
  4. Roll the putty across the trouble spot
  5. Lift up and—tada!—sand sticks to the putty
  6. Keep using fresh sections until your surfaces shine

Pros and Cons of Putty Method:

Pros

  • Stays waterproof in your tub
  • Keeps all your water where it belongs
  • Costs just a few dollars
  • Even kids can help with cleaning

Cons

  • Cleans small areas at a time
  • Gets less sticky after multiple uses
  • Works best on flat surfaces
  • Not your best friend for sand mountains

Creating a homemade siphon vacuum

Materials needed:

  • Garden hose (6-10 feet long)
  • Bucket or drainage area
  • Optional: broom handle or golf club shaft (fancy, right?)
  • Optional: cable ties or waterproof tape

Homemade siphon assembly:

  1. Cut your garden hose to about 6-10 feet
  2. Optional: Attach one end to a broom handle using tape or cable ties
  3. Drop one end near the sandy spots in your hot tub
  4. Place the other end in a bucket (must be lower than the tub)
  5. Fill the hose completely with water
  6. Cover one end with your thumb while submerging the other
  7. Release your thumb and watch the sand disappear!

Professional Tools for Hot Tub Sand Removal

Manual spa vacuums

  • Siphon-based vacuums: These clever tools use water pressure differences to create suction through a tube
  • Pump-action vacuums: Just pump away to generate suction power (bonus arm workout included!)
  • Venturi-style vacuums: Hook these up to your garden hose and let water pressure do the dirty work

Manual Vacuum Price Range:

ModelApproximate Price
MP Industries Micro Vac Kit$36.77
Jacuzzi Manual Spa Vacuum$33.59
MP Industries Garden Hose Vacuum$33.77
Water Tech Grit Getter$28.77

Battery-operated sand removers

Battery-powered options

  • Standard battery models: Run on replaceable batteries (usually D-cells) – grab some extras for movie night!
  • Rechargeable models: Feature built-in lithium-ion batteries you can use again and again

When to use each type of tool

Choose manual vacuums when:

  • Your hot tub is on the smaller side
  • You’re tackling occasional sand invasions
  • Your budget is saying “easy does it”
  • You don’t mind a bit of elbow grease

Choose battery-operated vacuums when:

  • Your tub needs frequent cleaning (beach house owners, we see you!)
  • You’ve got a bigger spa with lots of surface area
  • You’re battling super fine particles like sand and silt
  • Your back says “no thanks” to manual cleaning methods

Step-by-Step Sand Removal Process

Preparing your hot tub for cleaning

  1. Turn off ALL power to your hot tub system (safety first, folks!)
  2. Play detective and inspect the water for sand deposits—note where it’s settling
  3. Gather your cleaning arsenal (vacuum, baster, or siphon)
  4. Decide if you’re dealing with a “quick clean” situation or a “drain the whole tub” scenario

Do’s and Don’ts of Hot Tub Preparation

DoDon’t
Power down completely before cleaningRun pumps while removing sand
Inspect thoroughly for all sandy spotsRush through the cleaning process
Gather all tools before startingUse household cleaning products
Consider draining for beach-level sand invasionsScratch surfaces with abrasive tools

Targeting sand in different areas

Post-cleaning water maintenance

  1. Refill with fresh, balanced water if you drained the tub
  2. Test those chemical levels right away with test strips
  3. Adjust pH to the sweet spot between 7.2 and 7.8
  4. Add the right amount of sanitizer (your manufacturer’s instructions are your friend here)
  5. Stay vigilant! Retest water 2-3 times weekly
