Can you clean your spa filter in the dishwasher? It happened when cartridge manufacturers suggested using a dish soap instead of Trisodium Phosprate to remove grease deposits from their cartridges.
Has anyone seen a manufacturer of spa filters that suggest washing them in the dishwasher? There are some people online that suggest that they do it with no soap or use a no-heat drying process.
My dishwasher doesn't remove most of the tomato sauce, but it's a good model. So I thought I would try cleaning it.
The Dishwasher-Spa Filter Cleaning Test
Since my spa filter cartridge had not been cleaned in a while, I decided to remove it. Since it was a 15" tall, I was able to fit it on the lower rack of my dishwasher.
Since my spa filter cartridges had not been cleaned in a month, I decided to remove them. Since it was a 15" tall cartridge, I placed it on the lower rack of the dishwasher.
Even though it looked like it was a lot cleaner, there was still debris stuck in the pleats. Also, there was still a small amount of discoloration in the bottom half of the dish.
How to Clean Spa Filters
The old method is to hose the filter cartridge down using a garden hose nozzle. It's a bit wet and not very comfortable, but it does the best job.
Here's a step by step guide for cleaning spa and hot tub filter cartridges:
- Turn off spa, open filter canister and remove cartridge.
- Spray carefully with a high pressure hose nozzle to remove debris from each pleat.
- Soak the cartridge for 8 hours in TSP solution (1 cup TSP per 5 gallons hot water). Rinse clean.
- Soak the cartridge 1 hour in an acid solution (1 cup acid per 1 gallon cool water). Rinse clean.
- Soak the cartridge again in the TSP solution for 10 minutes to neutralize remaining acids.
- To kill remaining microbes, allow filter to dry completely before reinstalling.
In most cases, steps 3 and 4 are not necessary. For most applications, TSP or dry cleaner detergent is the best choice. Muriatic acid is also used to remove mineral deposits.
The Filter Flosser is a great tool to clean your spa filter. It can get in there and clean the filter's pleats.
- DO NOT clean spa filters in the dishwasher! It's not very effective and could damage the filter.
- DO NOT clean spa filters with a pressure washer, for obvious reasons.
- Dry dishwasher soap is OK, but laundry detergent is NOT OK.
- Remember to rinse the filter thoroughly after soaking to remove all chemical traces.
- DO NOT use DE powder as a spa filter aid. However, Puri-Fiber or Aqua-Perl may be used if desired.
